摘要： The sulphate ion content of an inorganic thiocyanate solution supersaturated in an inorganic sulphate is reduced by passing the solution through a slurried bed of a sulphate salt. The sulphate salt in the bed may be the same salt as the inorganic sulphate in the solution, while the sulphate in solution may have the same cation as the thiocyanate, e.g. sodium. The thiocyanate solution may be at an elevated temperature, e.g. 41 DEG C., and after passing through the bed may be passed through a zone of minimum turbulence, so as to settle entrained solid sulphate, and filtered or centrifuged to free it of solid. The thiocyanate solution may have been concentrated, to produce a supersaturated solution, before treatment and may be diluted afterwards. An apparatus for the continuous removal of sodium sulphate from a sodium thiocyanate solution containing it at supersaturation level has a port 8 for the introduction of sulphate salt into tank 1 while the supersaturated solution is continuously introduced through inlet 9. Rotating shaft 5 mixes by distributer disc 10 and flat scraper 11 prevents blocking of inlet 9 by sulphate. Baffles 12 above the mixing bed reduce the flow of liquid after it has passed through the bed while treated solution passes through slots 13 disposed in a ring around the vessel and enclosed by an annular overflow channel 14, from which the solution drains continuously via outlet pipe 15. Specifications 796,294, 824,361 and 864,096 are referred to.ALSO:Spent thiocyanate solution from acrylonitrile polymerization supersaturated in an inorganic sulphate is treated to reduce the sulphate ion content by passing the solution through a slurried bed of a sulphate salt. The sulphate in solution may have the same cation as the thiocyanate, and the sulphate in the main bed may be the same salt as the inorganic sulphate in supersaturated solution. Sodium sulphate is specified while the thiocyanate solution may be at an elevated temperature. Specifications 796,294, 824,361 and 864,096 are referred to.

摘要： Acrylonitrile is copolymerized with an aryl sulphonic ester of an unsaturated alcohol having the general formula CH2 = C(R)-R1-O-SO2-R2 in which R is hydrogen or methyl, R1 is a divalent hydrocarbon group, and R2 is an aryl group, e.g. allyl and methallyl para-toluene sulphonates, the proportions of the monomers being such that the copolymer contains at least 85 mol. per cent of acrylonitrile and 0.5 to 10 mol. per cent of ester, by forming an aqueous emulsion of the ester with less than the total amount of acrylonitrile and other monomers in the presence of an emulsifying agent and a protective colloid, adding gradually at a predetermined rate the remaining acrylonitrile, mixed with other monomers, if any, at the end of polymerization breaking the emulsion with water, and then reacting the copolymer obtained with ammonia or a primary, secondary, or tertiary amine. The copolymerization is described of acrylonitrile, allyl para-toluene sulphonate, and methyl acrylate in an aqueous emulsion containing polyvinyl alcohol as a protective colloid, the sodium salt of a sulphonated long chain alcohol as an emulsifier, and a mixture of ammonium persulphate and sodium bisulphite as a catalyst. Another emulsifier specified is the dioctyl (2-ethylhexyl) ester of the sodium salt of sulphosuccinic acid.

摘要： Regenerated cellulose threads, films and like products having a reduced water imbibition are produced by applying to the products a compound containing at least two 2 : 3-epoxypropyl groups and then heating to bring about reaction between the regenerated cellulose and the epoxy compound. The regenerated cellulose products may be treated with an aqueous solution of the 2 : 3-epoxypropyl compound, e.g. bis-(2 : 3-epoxypropyl)ethyl amine or tris-(2 : 3-epoxypropyl)amine, dried and then heated at 70-150 DEG C. for 5 minutes to 12 hours. Alternatively the impregnated products may be heated in a closed vessel to effect the epoxide-cellulose reaction and then washed and dried. The process may be modified by using a compound containing two or more 3-chloro-2-hydroxypropyl groups, e.g. tris-(3-chloro-2-hydroxypropyl)amine, the heat treatment being then effected in the presence of alkali to convert the 3-chloro-2-hydroxypropyl groups into 2 : 3-epoxypropyl groups on the products. Compounds containing one or more 2 : 3-epoxypropyl groups as well as 3-chloro-2-hydroxypropyl groups, e.g. N,N1-bis(2 : 3-epoxypropyl)-tetra-(3-chloro-2-hydroxypropyl)ethylene diammonium chloride, may also be used. In one example, staple fibres of "never-dried" viscose rayon are treated. Specifications 471,880, [Group IV], and 795,356 are referred to.

摘要： In the manufacture of artificial threads and like products by extruding a protein solution into a setting medium and hardening the products, the protein is esterified before or after extrusion and the esterified protein is treated with ammonia to convert at least a part of the esterified carboxyl groups into amide groups; the amidation may be effected before or after extrusion and in one form of the process, esterification is effected before extrusion and amidation after extrusion. Esterification may be effected with methanol in the presence of sulphuric acid or with dimethyl sulphate or ethylene oxide. Amidation may be effected with anhydrous or alcoholic ammonia or with aqueous ammonia solution preferably containing ammonium salts as buffers. When esterification and amidation follow extrusion, the extruded products are preferably first hardened in a formaldehyde-salt bath and may then be esterified as described in Specification 690,492. After amidation the products may be further hardened in a bath containing formaldehyde, sulphuric acid and one or more metal salts; alternatively or in addition, they may be insolubilized by treatment in a cyanate bath, as described in Specification 701,645. Examples are given.

摘要： A process for the production of regenerated protein fibres comprises extruding a solution of a protein and a polymeric compound having amide side chains into a setting medium, and treating the fibres so formed with formaldehyde. The protein solution may suitably be casein in alkaline solution, and the polymer, which generally amounts to 2-25 per cent by weight of the protein, is preferably either polyacrylamide or polymethacrylamide. The setting medium is desirably of the acid/salt type. The resulting fibres may be stretched after extrusion and are then treated in a bath containing formaldehyde, which is believed to cross-link the protein to the polymer. In addition to formaldehyde the bath may contain sulphuric acid and sodium and magnesium sulphates. The fibres obtained may optionally thereafter be submitted to other known hardening or insolubilizing treatments, and are said to exhibit a reduced degree of water imbibition. Specifications 614,506 and 701,645 are referred to.

摘要： o -Amino nonanoic acid is prepared by subjecting an unsaturated acid occurring naturally in vegetable oils and having the formula R-CH=CH(CH2)7COOH, R being an aliphatic monovalent radical, to oxidative cleavage to form azelaic semi-aldehyde OHC-(CH2)7COOH, together with a further aldehyde RCHO as byproduct, the oxidative cleavage being effected either by reacting the acid with hydrogen peroxide to form a corresponding dihydroxy substituted acid and oxidizing this acid to form the aldehydes or by reacting the acid with ozone to form an ozonide which is subjected to hydrolysis or catalytic hydrogenation to form the aldehydes, and then either reacting the azelaic semi-aldehyde with hydroxylamine to form azelaic semi-aldoxime and hydrogenating the aldoxime in the presence of a hydrogenation catalyst to the desired amino-nonanoic acid or hydrogenating the azelaic semi-aldehyde in the presence of ammonia and a hydrogenation catalyst to the same amino acid. In a modification of the process, esters of the aminononanoic acid are prepared following the same sequence of reactions and either starting with an ester of the original unsaturated acid or esterifying one of the intermediate products which contains an esterifiable carboxylic group, for example, the azelaic semi-aldehyde or dihydroxy acid. In examples: (1) oleic acid in dry ethanol is treated with ozonized oxygen and the resulting solution of ozonide is hydrogenated in presence of palladium on calcium carbonate as catalyst; the aldehyde mixture formed is reacted with hydroxylamine hydrochloride in presence of excess sodium acetate and the solution refluxed; after removal of solvent, pelargonic aldoxime is precipitated by excess of aqueous sodium carbonate and thereafter azelaic semi-aldoxime is precipitated on acidification; the azelaic semi-aldoxime is hydrogenated in ethanolic solution in presence of ammonia and a Raney nickel catalyst and the ammonium salt of the desired amino-nonanoic acid recovered from the product and converted into the free amino-acid; the aldehydic products of the oxidative cleavage may be separated before the oxime-formation step by distillation or the semi-carbazone method; (2) oleic acid is hydroxylated with hydrogen peroxide and acetic acid, and the resulting 9 : 10-dihydroxy stearic acid recovered and converted to its ethyl ester; the ester is oxidized in dry benzene with lead tetra-acetate and the so-obtained pelargonic aldehyde and the ethyl ester of azelaic semi-aldehyde recovered by distillation; the ethyl ester is converted into its oxime which is hydrogenated as in (1) to yield ethyl 9-amino nonanoate; (3) as in (2), the ethyl ester of the azelaic semi-aldehyde being hydrogenated in ethanolic solution in presence of ammonia and Raney nickel to form ethyl amino nonanoate. Reference is also made to linoleic and ricinoleic acids and their esters. According to the Provisional Specification, R is any monovalent radical.
