Abstract
The present invention relates to a process for the preparation of organo silicon disulfide compounds. The process involves reacting a mercaptoalkoxysilane with a dithiobis(benzothiazole) compound.
Claims11
A process for the preparation of organosilicon disulfide compounds of the formula:
- Z--R.sup.1 --S.sub.2 --R.sup.1 --Z I
- and ##STR7## comprising reacting (a) a dithiobis(benzothiazole) compound of the formula ##STR8## with (b) a mercaptosilane compound of the formula
- Z--R.sup.1 --SH IV
- wherein Z is selected from the group consisting of ##STR9## wherein R.sup.2 may be the same or different and is independently selected from the group consisting of an alkyl group having 1 to 4 carbons and phenyl;
- R.sup.3 may be the same or different and is independently selected from the group consisting of alkoxy groups having 1 to 8 carbon atoms and cycloalkoxy groups with 5 to 8 carbon atoms;
- and R.sup.1 is selected from the group consisting of a substituted or unsubstituted alkylene group having a total of 1 to 18 carbon atoms and a substituted or unsubstituted arylene group having a total of 6 to 12 carbon atoms.
