A vinylidene olefin may be subjected to hydroformylation in the presence of an unmodified cobalt catalyst to form a composition comprising a mixture of alcohol molecules having a specified amount of branching. In particular, the composition may carry a mixture comprising a reductive hydroformylation reaction product of a vinylidene olefin comprising an alcohol molecule represented by at least one of structures 3-5. The mixture has an average of from about 1.2 to about 2.1 branches per alcohol molecule. Ra and Rb may be the same or different and include a branched or unbranched alkyl group having from about 6 to about 14 carbon atoms, not branched by calculation. And the variable m is an integer from 0 to the number of carbon atoms in Rb. Rb'is a branched or unbranched alkyl group containing m + 1 less carbon atoms than Rb. 乙烯叉基烯烃可以在未改性的钴催化剂存在下经历加氢甲酰基化以形成包含具有指定支化量的醇分子的混合物的组合物。特别地，所述组合物可以带有包含乙烯叉基烯烃的还原加氢甲酰基化反应产物的混合物，所述乙烯叉基烯烃包含由结构3-5中的至少一个表示的醇分子。所述混合物具有平均约1.2至约2.1个支链/醇分子。Ra和Rb可以是相同或不同的并包含不计算支链含约6至约14个碳原子的支化或未支化烷基
