| titleOfInvention | The preparation of esters of carboxylic acids with hydroxyalkane sulphonic acids |
| abstract | Esters of carboxylic and hydroxyalkane sulphonic acids of the formula RCOO(CR1R11)n SO3X, wherein RCOO represents the acyloxy group of an aliphatic, cycloaliphatic or aromatic carboxylic acid containing at least 8 carbon atoms, R1 and R11 represent hydrogen or alkyl groups, n represents an integer of from 2 to 4 and X represents a salt-forming cation, are prepared by reacting a mixed anhydride of a carboxylic acid and boric acid with a water-soluble salt of a hydroxyalkane sulphonic acid. The reaction will proceed at room temperature but a temperature in the range of 50 DEG to 150 DEG C. is preferred. Isethionic acid is the preferred hydroxylakane sulphonic acid but 2-hydroxypropane and hydroxybutane sulphonic acids are also suitable. The salt may be formed from an alkali metal, calcium, magnesium or a tertiary amine. The products are useful detergents. Specifications 799,909 and 824,447 are referred to. |
