Abstract
A process for the production of a substituted alpha, beta dicarboxylic acid compound substantially free of tar and other resinous reaction byproducts comprising the reaction of an ethylenically unsaturated long chain compound having at least 10 carbon atoms and an ethylenically unsaturated alpha, beta dicarboxylic acid compound at conditions favoring the ENE reaction in the presence of a catalytically effective amount of an alkyl aluminum halide.

A process for the production of a substituted alpha, beta dicarboxylic acid compound substantially free of tar and resinous reaction byproducts which comprises the reaction of an ethylenically unsaturated alpha, beta dicarboxylic acid compound with an ethylenically unsaturated long chain compound having at least 10 carbon atoms at conditions favoring the "ENE" reaction in the presence of a catalytically effective amount of an alkyl aluminum halide.
The process for the production of substituted succinic acid compound substantially free of tar and resinous reaction byproducts which comprises the reaction at conditions favoring the "ENE" reaction of an ethylenically unsaturated long chain compound having at least 10 carbon atoms and maleic anhydride in the presence of a catalytically effective amount of ethylaluminum dichloride.
