Abstract

Fluorinated carboxylic acids are obtained by addition of hydrogen fluoride to compounds containing at least three carbon atoms, at least one carboxyl group, and at least one treble bond. Two molecules of hydrogen fluoride may be added at the treble bond, with the production of saturated compounds, or only one molecule may be so added, olefinic compounds being then obtained. The reaction may be effected at atmospheric temperature and pressure in the presence or absence of a solvent, e.g. methylene chloride or carbon tetrachloride. An example is given in which stearolic acid is treated with gaseous hydrogen fluoride to yield 9 : 10-difluorostearic acid. Other specified starting materials are acetylenedicarboxylic acid and phenylpropiolic acid. The fluorinated acids may be converted into their esters or amides. The products are useful as fungicides, insecticides, disinfectants and assistants in the textile industry, and if insoluble in water they may be used in the form of emulsions.
