摘要:
HIGH MELTING, HIGH MOLECULAR WEIGHT INTERPOLYMERS OF CARBON MONOXIDE WITH AT LEAST ONE UNSATURATED COMPOUND SUCH AS THE ALIPHATIC MONOOLEFINS, I.E., ETHYLENE, ARE PREPARED BY REACTING CARBON MONOXIDE WITH SAID UNSATURATED COMPOUNDS IN THE PRESENCE OF AN ARYL PHOSPHINE COMPLEX OF A PALLADIUM HALIDE AND CERTAIN INERT SOLVENTS.
摘要:
An improved catalyst composition for carbonylating olefinically unsaturated hydrocarbons with carbon monoxide and a hydroxylic compound comprises a zero-valent palladium or platinum complex incorporating stabilizing phosphine ligands, and excess ligand. Use of these catalyst compositions results in a high ratio of straight-chain to branch-chain product when employed in the carbonylation of alpha olefins to produce carboxylic acids, esters or acid anhydrides.
摘要:
PRODUCTION OF ALLYLIC ETHERS BY REACTING IN HIGH CONVERSION AN ALLYLIC ALCOHOL OF THE FORMULA WHERE R IS HYDROGEN, METHYL OR HYDROXYMETHYL AND R'' IS HYDROGEN OR METHYL, WITH ITSELF OR WITH A NONALLYLIC ALCOHOL IN THE PRESENCE AS CATALYST OF CUPRIC CHLORIDE OR BROMIDE OR ADDITIONALLY IN THE PRESENCE AS CATALYST PROMOTER OF AN ACIDIC MATERIAL OR AN ALLYLIC HALIDE, WHERE THE HALIDE IS CHLORIDE OR BROMIDE.
摘要:
A novel palladium-containing compound, HPd(CN)3, and its preparation are described. This compound is particularly useful as a catalyst for the copolymerization of carbon monoxide and ethylenically unsaturated monomers such as ethylene.
摘要:
HIGH MELTING, CRYSTALLINE INTERPOLYMERS OF CARBON MONOXIDE WITH ONE OR MORE UNSATURATED COMPOUNDS SUCH AS ALIPHATIC MONOOLEFINS PARTICULARLY ETHYLENE, ARE PREPARED BY REACTING CARBON MONIXIDE WITH SAID UNSATURATED COMPOUNDS IN THE PRESENCE OF SELECTED INERT SOLVENTS AND A CATALYTIC AMOUNT OF TETRAKIS(TRIARYL PHOSPHINE) PALLADIUM, PARTICULARLY TETRAKIS(TRIPHENYL PHOSPHINE) PALLADIUM.
