Abstract
Mixtures of isomeric decyl alcohols obtained by hydroformylation of butadiene to produce aldehyde mixtures, condensation of the aldehyde mixtures, isolated from the reaction product, to form an aldol mixture, and isolation and hydrogenation of the aldol mixture. The mixture of isomeric decyl alcohols, esterified using phthalic acid, gives a mixture of isomeric decyl phthalates which are plasticizers having excellent cold properties.
