Abstract
Anionic biodegradable detergents as exemplified by alkaline sulfate esters of n-alkyl-substituted hydroxypolyalkoxymethylcyclohexenes may be prepared by condensing butadiene with allyl alcohol, ring alkylating the resultant hydroxymethylcyclohexene with an olefin in the presence of a free-radical generating compound to form an alkyl-substituted hydroxymethylcyclohexene, alkoxylating this compound to form an alkyl-substituted hydroxypolyalkoxymethylcyclohexene, sulfating the latter compound and neutralizing the sulfate ester with an alkaline material to form the desired product.
