    • A process for the production of triglycerides of C.sub.1 -C.sub.4 alkyl esters of C.sub.6 -C.sub.22 fatty acids:a) where dry sodium carbonate catalyst is dissolved in glycerol and mixed with a molar excess of preferably the methyl ester of C.sub.6 -C.sub.22 fatty acid at a temperature between about 150.degree. C. and 250.degree. C. at less than atmospheric pressure and under substantially anhydrous conditions to produce an initial reaction mixture containing the corresponding triglycerides of said fatty acids, and partially reacted glycerol with unreacted hydroxyl groups (OH values 10-40),b) thereafter, a portion of the initial reaction mixture is reacted with additional C.sub.1 -C.sub.4 alkyl ester of C.sub.6 -C.sub.22 fatty acid under conditions to achieve substantially full conversion of said unreacted hydroxyl groups (OH values of 5 or less), andc) a product containing the corresponding triglycerides of said fatty acids is separated from unreacted alkyl ester and from the sodium carbonate catalyst. Improved light colored triglyceride products are achieved and can be separated readily from the sodium carbonate catalyst by filtration.
    • 制备C 6 -C 22脂肪酸的C 1 -C 4烷基酯的甘油三酸酯的方法:a)其中将干燥的碳酸钠催化剂溶解在甘油中,并与摩尔过量的优选C6-C22脂肪酸的甲酯在 温度在约150℃至250℃之间,低于大气压和基本无水条件下,以产生含有所述脂肪酸的相应甘油三酸酯和部分反应的甘油与未反应的羟基的初始反应混合物(OH值10- 40),b)此后,一部分初始反应混合物与另外的C 6 -C 22脂肪酸的C 1 -C 4烷基酯在使所述未反应的羟基基本上完全转化(OH值为5以下)的条件下反应, 和c)含有所述脂肪酸的相应甘油三酯的产物与未反应的烷基酯和碳酸钠催化剂分离。 实现了改进的浅色甘油三酸酯产物,并且可以通过过滤容易地与碳酸钠催化剂分离。

    • Fabric softeners intended for the treatment of fabrics after washing are disclosed. These softeners contain as active substance a combination of carboxylic acids and amines and/or quaternary ammonium compounds containing a long chain alkyl or alkenyl radical and comprise:(a) one or more amines corresponding to general formulae (I) and/or (II) below: ##STR1## in which: R.sup.1 and R.sup.2 may be the same or different and, independently of one another, represent hydrogen, straight-chain or branched C.sub.1 -C.sub.20 alkyl radicals, in addition to which R.sup.2 may represent a hydroxy group or a group corresponding to the following formula: ##STR2## where: R.sup.5 is hydrogen or a straight-chain or branched C.sub.1 -C.sub.6 alkyl radical; andR.sup.3 and R.sup.4 may be the same or different and, independently of one another, represent hydrogen, staight-chain or branched C.sub.1 -C.sub.6 alkyl radicals or hydroxyalkyl radicals containing from 1 to 6 carbon atoms in the straight-chain alkyl radical; andp and q are numbers of from 0 to 22, the sum (p+q) being in the range of 0 to 22; and/or one or more ammonium compounds derived from such amines by quaternization;(b) one or more straight-chain or branched, saturated or unsaturated C.sub.1 14 C.sub.24 carboxylic acids; and(c) optionally, other substances typically used in fabric softeners.This active-substance combination is readily and inexpensively available and provides the treated fabrics with a soft, full feel.
