摘要:
The novel 4-aceto-6,8a-ethano-1,1,6-trimethyl-1,2,3,5,6,7,8,8aoctahydronaphthalene can be isolated from acetylated thujopsene and thujopsene isomers and is a valuable perfume agent.
摘要:
A method for isomerizing olefinic hydrocarbons which employs a zinc arsenide catalyst, the arsenide being present in relation to the zinc in a molal ratio between about 0.33 and 3.0.
摘要:
A method for preparing a hydrocarbon conversion catalyst by providing a composite composed of alumina having associated therewith a Group VIB, VIIB or VIII metal or compound and contacting the composite with an activator system comprising carbon monoxide and sulfuryl fluoride or thionyl fluoride. The catalysts so prepared are useful in such hydrocarbon conversion processes as isomerization, hydrocracking, reforming, alkylation, disproportionation, polymerization and hydrogenation.
摘要:
1. A PROCESS FOR THE ISOMERIZATION O A PINENE-CONTAINING FEED MATERIAL WHICH CONSISTS IN HEATING SAID MATERIAL IN AN INERT ATMOSPHERE AT TEMPERATURES BETWEEN 75*C. AND 175*C. IN CONTACT WITH CATALYST CONSISTING ESSENTIALLY OF A CARBONATE-ACTIVATED CARBON WHEREBY CAMPHENE IS RECOVERED IN GOOD YIELD.
摘要:
Novel compositions are prepared by impregnating inert supports with H.sub.4 Mo(CN).sub.8 and/or H.sub.4 W(CN).sub.8 and subsequently activating by heating in an inert environment at about 400.degree.-600.degree. C. The materials, particularly when supported on aluminous or siliceous supports, are useful as catalysts for simultaneously isomerizing and disproportionating olefins.
