Catalyst and dehydrogenation process

Process for producing nitriles

TETRAHYDROTHIOPHENE-1,1-DIOXIDES (SULFOLANES) ARE EMPLOYED AS REACTION MEDIA FOR CONVERSION OF AMMONIUM AROMATIC CARBOXYLATES TO AROMATIC NITRILES.

Olefin disproportionation catalyst

A catalyst for the olefin disproportionation of unsaturated hydrocarbons is provided comprising a physical mixture of a solid disproportionation catalyst and a double bond isomerization catalyst wherein the double bond isomerization catalyst is further treated with a base.

Sulfur-containing polyamide

A NOVEL SULFUR-CONTAINING POLYAMIDE HAS THE REPEATING UNITS $NR''-R-S-R-CO$ WHEREIN EACH R IS A SATURATED ALIPHATIC OR AROMATIC RADICAL HAVING UP TO 8 CARBON ATOMS AND R'' IS HYDROGEN, PHENYL OR A SATURATED ALIPHATIC RADICAL HAVING UP TO 6 CARBON ATOMS. THE SULFUR-CONTAINING POLYAMIDES OF THE INVENTION ARE USEFUL FOR CONVERSION INTO FIBERS, FILMS, FORMED OBJECTS, AND COATINGS.
