| abstract | 1,128,127. 2-Chloroethane sulphonic acid. PRODUITS CHIMIQUES PECHINEYSAINT-GOBAIN. 20 Feb., 1967 [21 Feb., 1966], No. 7990/67. Heading C2C. 2-Chloroethane sulphonic acid is prepared by heating a reaction medium comprising 2- chlorethane sulphonyl chloride and an alcohol, with or without the presence of water. The temperature is preferably near the boiling point of the reaction medium and the proportion of alcohol and water is preferably at least equal to that theoretically required, based on the stoichiometry of the reaction, and preferably from 2 to 10 times that theoretical proportion. One mole of 2-chloroethane sulphonic acid is suitably reacted with 1 or 2 moles of an alcohol ROH, wherein R is an alkyl, alkenyl, alkynyl, aryl, alkaryl, cycloalkyl or cycloalkenyl radical. Organic solvents may also be present. When hydrochloric acid is a by-product, it may be removed by passing an inert gas, such as nitrogen or argon, through the reaction medium. Secondary products can be separated by conventional methods, e.g. distillation, and the 2-chloroethane sulphonic acid in the residue purified, preferably by distillation under reduced pressure. |
