    • The present invention relates to a method for preparing trimethylolpropane (TMP) comprising the steps of: 1) synthesizing trimethylolpropane by using n-butyl aldehyde, an aqueous solution of formaldehyde and an aqueous solution of alkali metal hydroxide through aldol condensation reaction and Cannizzaro reaction; 2) extracting trimethylolpropane from a resultant mixture of the step 1) by contacting the resultant mixture with an alcohol having 6 to 10 carbons; 3) removing alkali metal ion from a resultant extract of the step 2) by contacting the resultant extract with water; and 4) distilling the alkali metal ion-removed extract obtained from the step 3). According to the present invention, a separate formaldehyde recovery process can be omitted, the extraction efficiency of TMP can be maximized with using a relatively small amount of extraction solvent, the separation and recovery processes for extraction solvent can be simplified since a mixture of solvents is not used for TMP extraction, and the yield of TMP can be maximized while the amount of generated waste water can be minimized, thereby producing TMP economically with good efficiency.
    • 本发明涉及一种制备三羟甲基丙烷(TMP)的方法,包括以下步骤:1)通过醛醇缩合反应和Cannizzaro反应,使用正丁醛,甲醛水溶液和碱金属氢氧化物水溶液合成三羟甲基丙烷; 2)通过使所得混合物与具有6至10个碳的醇接触,从步骤1)的所得混合物中提取三羟甲基丙烷; 3)通过使得到的提取物与水接触,从步骤2)的所得提取物中除去碱金属离子; 和4)蒸馏从步骤3)获得的碱金属离子去除的提取物。 根据本发明,可以省略单独的甲醛回收方法,使用相对少量的萃取溶剂可以最大限度地提高TMP的萃取效率,因为溶剂混合物的分离和回收方法可以简化,因此可以简化萃取溶剂的分离和回收过程 不用于TMP提取,并且可以最大限度地提高TMP的产率,同时可以最大限度地减少产生的废水量,从而以高效率经济地生产TMP。
