    • Branched, substantially unsaturated fatty alcohol polylglycol ethers are produced by a process which comprises the steps of: (a) dimerizing unsaturated C16-22 fatty acid to form a dimer fraction and a monomer fraction comprised of branched, substantially unsaturated fatty acids and straight chain saturated fatty acids, (b) removing the monomer fraction from the dimerization step, (c) converting the branched, substantially unsaturated fatty acids from step (b) into the corresponding fatty acid methyl esters, (d) hydrogenating the branched, substantially unsaturated fatty acid methyl esters with the double bonds intact to form the corresponding branched, substantially unsaturated fatty alcohols and (e) alkoxylating the branched, substantially unsaturated fatty alcohols. The fatty alcohol polylglycol ethers thus produced exhibit improved performance properties and greater oxidative stability than standard unsaturated fatty alcohol sulfates.
    • 分支的,基本上不饱和的脂肪醇聚乙二醇醚通过包括以下步骤的方法生产:(a)使不饱和C16-22脂肪酸二聚以形成二聚体部分和由支化的,基本上不饱和的脂肪酸组成的单体级分和直链饱和 脂肪酸,(b)从二聚步骤中除去单体部分,(c)将步骤(b)中的支链基本上不饱和的脂肪酸转化成相应的脂肪酸甲酯,(d)将支链的,基本上不饱和的脂肪酸 具有双键的甲酯完整以形成相应的支链,基本上不饱和的脂肪醇,和(e)使支化的基本上不饱和的脂肪醇烷氧基化。 如此制备的脂肪醇聚乙二醇醚与标准不饱和脂肪醇硫酸盐相比表现出改进的性能和更高的氧化稳定性。
