Abstract: PREPARATION OF METHACRYLIC DERIVATIVES FROM TERTIARY BUTYL-CONTAINING COMPOUND The present invention relates to a process for the conversion of tertiary-butyl-containing compounds to methacrylic derivatives, and more particularly to a process for the conversion of tertiary-butyl-containing compounds selected from the group consisting of alkyl tertiary-butyl ethers, tertiary-butyl alcohol, isobutylene dimer (2,2,4-trimethylpentene) and isobutylene trimer, to methacrolein, methacrylic acid or methacrylonitrile.

Abstract: The invention is the extrusion of sulfur from thiodinitriles to obtain the corresponding dinitrile by heating the thiodinitrile at a temperature of 200 DEG to 700 DEG C. For example, sulfur is extruded from thiodipropionitrile to obtain adiponitrile. This extrusion reaction can be either a strictly thermal reaction employing no other reactant or a reaction conducted in the presence of other gases, liquids or solids.
