Abstract

Method for obtaining sulfonylchlorides of the following formula of structure: wherein r1 is selected from the group consisting of hydrogen-halogen groups nitrolevialquilolevialcoxilo and amino; r2 of the group consisting of hydrogen and levialkyl groups r3 is a member of the group consisting of hydrogen and chlorosulfonyl groups which comprises contacting chlorosulfonic acid and an aniline compound of the general structure formula ** where r1 and r2 have the above meaning for each in an excess molar ratio of the said chlorosulfonic acid temperature and for sufficient time to sulfonate said aniline compound by reaction thereof with chlorosulfonic acid until the end of the reaction with what is consumed in it almost all the aniline compound and a product mixture containing derivatives of the sulfonation of said compound is obtained of aniline between them the above-mentioned chlorosulfonyl; then add to that product mixture phosphorus trichloride and keep the resulting mixture at a temperature and for a sufficient time for the reaction of the phosphorus trichloride and the corresponding increase of the chlorosulfonyl content in the product mixture, with the addition of the phosphorus trichloride gradually at a rate substantially equal to the consumption thereof in said reaction.
