当前国外生产脂肪醇的工业方法很多,主要分为羰基合成法、齐格勒法、正构烷烃直接氧化法和动植物油脂加氢法.其中以齐格勒法醇质量最好,可与天然油脂醇相比.生产洗涤剂用的脂肪醇类及其最大的生产公司主要集中在美国、西欧和日本,1992年产能合计约125万t,产量78.2万t,消费量76万t以上.洗涤剂用脂肪醇主要用于脂肪醇乙氧基化物和脂肪醇硫酸盐等.
At present, there are many industrial methods for the production of fatty alcohols in foreign countries, which are mainly divided into oxo-synthesis methods, Ziegler’s method, direct oxidation of n-alkanes, and hydrogenation of animal and vegetable oils. Among them, Ziegler’s alcohol has the best quality and can be used naturally. Compared with oils and alcohols, the production of fatty alcohols for detergents and their largest production companies are mainly concentrated in the United States, Western Europe and Japan. In 1992, the total production capacity was approximately 1.25 million tons, the output was 782,000 tons, and the consumption was more than 760,000 tons. Fatty alcohols are mainly used in fatty alcohol ethoxylates and fatty alcohol sulfates.
