A process for preparing compositions containing certain quaternary ammonium compounds from tertiary amines selected from the group consisting of tertiary amines containing one or two long-chain aliphatic groups, and mixtures thereof, is disclosed. The process comprises reacting the tertiary amine with dimethyl sulfate, diehtyl sulfate, or trimethyl phosphate. The reaction is performed in a reaction medium selected from the group consisting of compounds which have a melting point below about 100°C, preferably are capable of dissolving the desired quaternary ammonium compound, and which contain either (i) an ester linkage derived from a fatty acid, (ii) a primary hydroxyl group, or (iii) both, and mixtures of said compounds. The reaction typically is performed at a temperature between about 50°C and about 150°C, for a length of time sufficient to convert at least a portion of the tertiary amine to the desired quaternary ammonium compound. The compositions obtained in this way can be utilized for conditioning clothes, such as in an automatic laundry dryer.
本发明公开了一种利用叔胺制备含有某些季铵化合物的组合物的工艺,叔胺选自含有一个或两个长链脂肪族基团的叔胺及其混合物。该工艺包括将叔胺与硫酸二甲酯、硫酸二乙酯或磷酸三甲酯反应。反应在反应介质中进行,该反应介质选自熔点低于约 100°C,最好能溶解所需季铵化合物,且含有(i) 源自脂肪酸的酯键,(ii) 伯羟基,或 (iii) 两者的化合物,以及上述化合物的混合物。反应通常在约 50°C 至约 150°C 的温度下进行,反应时间足以将至少一部分叔胺转化为所需的季铵化合物。以这种方式获得的组合物可用于衣物调理,例如在自动洗衣干衣机中使用。
