Abstract
Hydroxylated fatty acid esters, particularly castor oil, are dehydrated by treating the ester with a small amount of a b -naphthol-sulphonic acid, the compounds specified being 2-naphthol6-sulphonic acid and 2-naphthol-8-sulphonic acid. Alkali metal and ammonium salts of the b -naphthol-sulphonic acid may be used, the free acid being generated in situ by decomposition thereof, such as by the double decomposition of the salt with an acidic salt, sodium bisulphate being specified. The dehydration is preferably effected at a temperature of 190-260 DEG C.; in the case of castor oil, 190-290 DEG C. is exemplified. The time required varies from 3/4 to 2 hours after the reaction mass temperature reaches 190 DEG C. The reaction may be carried out in an open kettle. At the termination of the reaction, the b -naphthol-sulphonic acid is removed from the reaction mixture by filtration. Pale products which are good drying oils are obtained and may be used as such or bodied. They may be incorporated with the usual ingredients to produce varnishes, paints, &c.ALSO:Hydroxylated fatty acid esters, particularly castor oil, are dehydrated by heating the ester with a small amount of a b -naphthol-sulphonic acid, the compounds specified being 2-naphthol-6-sulphonic acid and 2-naphthol-8-sulphonic acid.
