Alkyl sulfates degradation products

Reactions other than those of the nucleophilic reactivity of alkyl sulfates iavolve reactions with hydrocarbons, thermal degradation, sulfonation, halogenation of the alkyl groups, and reduction of the sulfate groups. Aromatic hydrocarbons, eg, benzene and naphthalene, react with alkyl sulfates when cataly2ed by aluminum chloride to give Fhedel-Crafts-type alkylation product mixtures (59). Isobutane is readily alkylated by a dipropyl sulfate mixture from the reaction of propylene ia propane with sulfuric acid (60). 

Preservatives are necessary in products to ensure microbiological robustness. Alkyl sulfates and alkyl ether sulfates, for example, are subject to degradation by... 

Linear ethoxylates are the preferred raw materials for production of ether sulfates used in deteigent formulations because of uniformity, high purity, and bio degradability. The alkyl chain is usually in the C12 to C13 range having a molar ethylene oxide alcohol ratio of anywhere from 1 1 to 7 1. 

The ratio of LE s to DMH s produced Is generally relatively constant regardless of the operating conditions or the olefin used. Similar constant ratios are also obtained in the products of conventional alkylations, two-step alkylations (In which butyl sulfates react), and degradation reactions between Tfl> s and sulfuric acid. This finding suggests that a common Intermediate Is Involved In the production of most LE s and DMH s. 1-Butene cannot be considered this Intermediate since It Is sometimes present only In at most minute quantities. 1-Butene Is mentioned since It has been suggested as the C4 olefin that leads to production of DMH s (9,...
