<p>DETERGENT RANGE ALDEHYDE AND ALCOHOL MIXTURES AND DERIVATIVES, AND PROCESS THEREFOR Novel, liquid mixtures of isomeric aldehydes and alcohols and their derivatives are described in the C11 - C16 carbon range, the compounds being characterized by a main carbon branched at the 2-position and moderate additional branching in most isomers; the aldehyde mixtures are prepared by an economic route from lower cost olefins such as propylene, using 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 mixtures can be exemplified by a mixture of compounds wherein the compounds are represented by one of the following structures: having from 11 to 16 carbon atoms, in which R has 6 to 8 carbon atoms, and R' has from 3 to 6 carbon atoms, with most of the compounds having additional methyl or ethyl branches, and in which M is hydrogen or a salt-forming cation. 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.</p> |
