摘要： A PROCESS FOR SEPARATING THE MONO-CHLOROMETHYLATION FROM THE DI-CHLOROMETHYLATION PRODUCTS OF AROMATIC HYDROCARBONS OF C10 OR LOWER WHOSE MONO-CHLOROMETHYLATION PRODUCTS HAVE A MELTING POINT OF ABOUT 25*C. OR HIGHER. A CHLOROMETHYLATION REACTION MIXTURE IS HEATED WITH A C6 TO C9 AROMATIC HYDROCARBON IN THE LIQUID PHASE TO DISSOLVE THE MONO-CHLOROMETHYLATION AND DI-CHLOROMETHYLATION PRODUCTS AND IS THEN COOLED TO PRECIPITATE SOLID DI-CHLOROMETHYLATION PRODUCT. SOLID DI-CHLOROMETHYLATION PRODUCT IS SEPARATED FROM THE AROMATIC HYDROCARBON SOLUTION AND WASHED WITH A C5 TO C8 SATURATED HYDROCARBON IN THE LIQUID PHASE TO HIGH PURITY. THE AROMATIC HYDROCARBON SOLUTION IS VAPORIZED TO LEAVE A RESIDUE INCLUDING THE MONO-CHLOROMETHYLATED PRODUCT. THE RESIDUE IS HEATED WITH A SATURATED C5 TO C8 HYDROCARBON N THE LIQUID PHASE TO DISSOLVE MONO-CHLOROMETHYLATED PRODUCT THEREIN. THEN THE HOT SATURATED HYDROCARBON S SEPARATED FROM UNDISSOLVED SOLIDS AND IS COOLED TO PRECIPITATE SOLID MONO-CHLOROMETHYLATED PRODUCT, WHICH IS THEN RECOVERED FROM THE SATURATED HYDROCARBON.

摘要： Aromatic compounds may be separated from paraffin-aromatic mixtures by using a solvent consisting of a solution of an aromatic dissolved in the same aromatic in its protonated form with aluminum chloride, (ArH) (Al2Cl7), wherein a liquid paraffinic phase and a liquid aromatic phase are formed, separating the phases and adding HCl to the aromatic phase to react with the solvent and adjusting the temperature to form a solid phase having the following formula:
摘要翻译：通过使用由溶解在其质子化形式的相同芳族化合物的芳族化合物与氯化铝[ArH] [Al 2 Cl 7]组成的溶剂，将芳族化合物与石蜡 - 芳族混合物分离，其中液体石蜡相和液体芳族化合物相，分离相，并向芳香相中加入HCl与溶剂反应，并调节温度以形成具有下式的固相：[ArH] [AlCl 4]，然后可以从本身的芳族化合物分离出来混合物。在上式中，Ar表示的芳香族是单体，异亚芳基，五甲基苯，六甲基苯或多核芳烃比单核芳香族更碱性。 [ArH] [AlCl4]可以以优选的方式用作溶剂。
