    摘要: Novel, liquid mixtures of isomeric aldehydes and alcohols are described in the C.sub.11 -C.sub.16 carbon range, the compounds being characterized by a main carbon branched at the position and moderate additional branching in most isomers; the aldehyde mixtures are prepared by an economic route from olefins involving oxo and aldol reaction with the reaction conducted in such a way as to give a high percentage of aldolable product, and preferably with a base catalyzed aldol reaction conducted under conditions to make high conversions attainable. The aldehyde mixtures can be hydrogenated to alcohols and converted to novel ethoxylates or sulfate compositions suitable for use as biodegradable detergents; or hydrogenated and oxidized to novel carboxylic acid compositions also suitable for detergent use.
