    摘要: An improved process for production of phenylalkylsulfonate compounds whereby the proportion of the 2-alkylphenylsulfonate isomer is reduced relative to the higher numbered isomers thereof (3-alkyl; 4-alkyl; etc.). After alkylation of aromatic compounds to produce a mixture of alkylbenzenes, the 2-alkylbenzene isomer is selectively cracked to lower boiling products, leaving the higher numbered isomers substantially unreacted. Subsequent sulfonation results in alkylphenylsulfonate derivatives having improved detergency properties.

    摘要: Disclosed is a continuous process for the sulfonation of an alkylaromatic reactant involving heating liquid sulfur trioxide in a vaporizer and mixing this sulfur trioxide gas stream with a hexane-alkylaromatic stream containing about 1 to about 3 wt. % quantity of a promoter, which can be either sulfuric acid or an alkyl benzene sulfonic acid, in a sulfonator - static inline mixer, mixing water with the sulfonated product as it passes to the water reactor - static inline mixer, passing the aqueous sulfonated product through degassing column-heat exchanger apparatus and separating the sulfonated product from the aqueous sulfuric acid. The reaction is conducted under controlled temperature and pressure conditions.

    摘要: Aromatic sulfonates having, respectively, preferential oil-, and water- and alcohol-solubility are prepared by reacting aromatic compounds and sulfuric acid in a medium capable of liquid-liquid extraction with water; the product stream is then subjected to countercurrent extraction against water in a first multi-stage column; the water stream is next subjected to countercurrent extraction against a water-immiscible higher alcohol in a second multi-stage column; and the sulfonate having preferential water- and alcohol-solubility, which has transferred from the product stream, to the water stream, and finally to the higher alcohol, is recovered from the latter as the free acid or as a salt thereof. The process is especially adapted to the production of dinonylnaphthalene disulfonic acid.
