DOCUMENT TYPE: Patent CA Section: 46 (Surface Active Agents and Detergents) Biodegradable detergents such as ammonium (n-octylcyclohexyl)methanosulfate (I) [55053-41-3] were prepd. 55053-41-3 is also in the experiment. Thus, hydroxymethylcyclohexane [100-49-2] was alkylated with 1-octene [111-66-0] at 80-5.degree. for 4 h in the presence of Bz2O2 and HCl to give hydroxymethyl-n-octylcyclohexane [54843-86-6], treated with H2SO4, and neutralized with NH4OH to prep. I. .
