Abstract

The vulcanization of rubber is accelerated by the addition of accelerators which contain the grouping <FORM:0448414/IV/1> where n is 1 or 2, R is an alkyl or carbamyl alkyl group, R1 is hydrogen, an alkyl, aralkyl or aryl hydrocarbon radical or a heterocyclic radical such as furfuryl and tetrahydrofurfuryl, and R2 is the same as R1 or an alpha alkacyl radical. The open bonds are preferably attached to a substituted or unsubstituted ortho arylene group. Substituents mentioned which may be carried by the arylene group are nitro, halogen, hydroxy, alkoxy and amino. The compounds may be prepared by bringing together in a solvent a mercaptothiazole or a salt thereof and a halogenated aliphatic acid amide. Solvents mentioned are water, alcohol and acetone. In examples: (1) a solution of sodium benzothiazyl-1-mercaptide in acetone is refluxed for \ba1/2\be hour with dichloroacetanilide to yield phenyl carbamyl methyl di-(benzothiazyl 1-sulphide); (2) in a similar manner carbamyl methyl di(benzothiazyl 1-sulphide) is prepared by refluxing in acetone solution sodium benzothiazyl mercaptide, ammonium chloride and dichloroacetamide; (3) carbamyl methyl benzothiazyl 1-mercaptide is made by refluxing ammonium chloride, monochloracetamide, and sodium benzothiazyl 1-mercaptide; (4) phenyl carbamyl methyl benzothiazyl 1-sulphide is made by heating to a temperature below 70 DEG C. for 45 mins. sodium benzothiazyl 1-mercaptide and chloro-acetanilide in alcohol solution. A long list is given of alternative mercapto thiazoles and of halogenated aliphatic acid amides which may be used in preparing the accelerators of the present invention. It is stated that although not invariably necessary, it is desirable to use activators with the accelerators of the present invention.ALSO:The vulcanization of rubber is accelerated by the addition of accelerators which contain the grouping <FORM:0448414/V/1> where n is 1 or 2, R is an alkyl or a carbamy alkyl group, R1 is hydrogen, an alkyl, aralkyl or an aryl hydrocarbon radical, or a heterocyclic radical such as furfuryl or tetrahydro furfuryl, and R2 is the same as R1 or an alpha alkacyl radical.
