    • There is provided a new branched primary alcohol composition and the sulfates, alkoxylates, alkoxy sulfates and carboxylates thereof exhibiting good cold water detergency and biodegradability. The branched primary alcohol composition has an average number of branches per chain of 0.7 to 3.0, having at least 8 carbon atoms and containing both methyl and ethyl branches. The primary alcohol composition may also contain less than 0.5 atom% of quaternary carbon atoms, and a significant number of ethyl branches, terminal isopropyl branches, and branching at the C3position relative to the hydroxyl carbon. The process for its manufacture is by skeletally isomerizing an olefin feed having at least 7 carbon atoms or by dimerising a C6-C10olefin, followed by conversion to an alcohol, as by way of hydroformylation, and ultimately sulfation, alkoxylation or both to obtain a detergent surfactant. Useful skeletal isomerization catalysts include the zeolites having at least one channel with a crystallographic free diameter along the x and/or y planes of the [001] view ranging from 42 to 70 nanometer. Useful dimerisation catalysts include a combination of a nickel carboxylate with an alkyl aluminium halids, or a combination of a nickel chelate with an alkyl aluminium alkoxide.
    • 提供了一种新的支链伯醇组合物,其表现出良好的冷水洗涤性和生物降解性的硫酸盐,烷氧基化物,烷氧基硫酸盐和羧酸盐。 支链伯醇组合物具有至少8个碳原子并含有甲基和乙基分支的每个链的平均支链数为0.7-3.0。 伯醇组合物还可以含有小于0.5原子%的季碳原子,并且相对于羟基碳,在C3位置上有大量的乙基支链,末端异丙基支链和支链。 其制造方法是通过骨架异构化具有至少7个碳原子的烯烃原料,或通过使C6-C10烯烃二聚化,然后转化成醇,通过加氢甲酰化,最终硫酸化,烷氧基化或两者来获得洗涤剂 表面活性剂。 有用的骨架异构化催化剂包括具有至少一个具有沿[001]视图的x和/或y平面的结晶学自由直径范围为42至70纳米的通道的沸石。 有用的二聚催化剂包括羧酸镍与烷基铝卤化物的组合,或镍螯合物与烷基铝醇盐的组合。
