Abstract: Vapor phase catalytic hydrogenation of maleic anhydride to gamma-butyrolactone is achieved in a conversion of 95% or more and a selectivity of 80% or more during a prolonged period of production. The process uses an activated catalyst prepared by reducing a catalyst composition comprising 30-65% by weight of CuO, 18-50% by weight of ZnO and 8-22% by weight of Al2O3, and activating the reduced catalyst composition in hydrogen at an activation temperature of at least 400 DEG C., preferably 400 DEG to 525 DEG C., and optimally about 425 DEG C. The process suitably is carried out under predetermined and advantageous process conditions, including a defined molar ratio of hydrogen to maleic anhydride in the vapor reactant stream, a selected pressure during hydrogenation, a defined feed rate space velocity, a predetermined contact time, and a suitable reaction temperature.

Abstract: 2083848 9204383 PCTABS00011 This invention relates to a coating composition which can be cured by exposure to radiation energy in the presence of a cationic photoinitiator. The composition comprises a mixture of between about 1 and about 75 wt. % of a reactive vinyl or alk-1-enyl ether cyclocarbonate having formula (I) wherein R is hydrogen or lower alkyl; R' is C2 to C4 alkylene; n has a value of from 0 to 4 and n' has a value of from 1 to 4 and between about 99 and about 25 wt. % of a polymerizable compound containing an onium salt initiator which is normally insoluble in said polymerizable compound or a mixture thereof. The invention also relates to the use of the composition as a protective coating on a substrate. Preferably, the cyclocarbonate is prepared by a two-stage liquid phase process wherein an alk-2-enyl glycidyl ether having formula (II) wherein R is hydrogen or lower alkyl; R' is C2 to C4 alkylene, n has a value of from 1 to 4 and n' has a value of from 0 to 4, is catalytically isomerized to the corresponding alk-1-enyl glycidyl ether in the first-stage of the reaction and the reaction mixture of the first-stage, containing the isomerization catalyst is then contacted with carbon dioxide in the presence of a phase transfer catalyst under a pressure ranging from atmospheric to about 400 psig in the second stage of the reaction.
