ABSTRACT:
A process for preparing alcohols from internal olefins is disclosed. Briefly, the process comprises (a) hydroformylation of internal olefins to aldehydes using a small amount of a ligand modified recycled rhodium catalyst, (b) separating the reaction product from the catalyst by flash vacuum distillation, (c) hydrogenating the aldehydes to form a product containing alcohols, and (d) removing impurities and recovering the desired alcohol product. An important feature of this process, centers around the use of internal olefins to make an alcohol product which has a large amount of linear alcohol and 2-methyl-branched alcohol in the product.
