  • Process for the synthesis of aliphatic alcohol-containing mixtures
    Patent number: 4477594
    Abstract: A process for the synthesis of mixtures which include saturated aliphatic alcohols is disclosed. In the first step of the process, the first catalyst activation stage, a catalyst, which comprises the oxides of copper, zinc, aluminum, potassium and one or two additional metals selected from the group consisting of chromium, magnesium, cerium, cobalt, thorium and lanthanum, is partially activated. In this step, a reducing gas stream, which includes hydrogen and at least one inert gas, flows past the catalyst at a space velocity of up to 5,000 liters (STP) per hour, per kilogram of catalyst. The partially activated catalyst is then subjected to the second step of the process, second-stage catalyst activation. In this step, the catalyst is contacted by an activation gas stream comprising hydrogen and carbon monoxide present in a volume ratio of 0.5:1 and 4:1, respectively, at a temperature of 200.degree. to 450.degree. C. and a pressure of between 35 and 200 atmospheres.

  • Process for the preparation of .beta.-phenylethyl alcohol via homologation
    Patent number: 4158100
    Abstract: .beta.-Phenylethyl alcohol is prepared by the homologation of benzyl alcohol with hydrogen and carbon monoxide in the presence of a cobalt catalyst promoted with ruthenium and iodine compounds, in the presence of water at a temperature from 100.degree. to 165.degree. C. High yields and selectivity of the .beta.-phenylethyl alcohol are obtained.

  • Catalyst recovery process
    Patent number: 4087623
    Abstract: Disclosed is a method of removing iodine-containing compounds from the reaction product of iodine-catalyzed acetoxylation, wherein an olefin is reacted with oxygen and a carboxylic acid, and the iodine is recycled to the reactor.

  • Process for the production of epoxides
    Patent number: 4012423
    Abstract: Epoxy compounds are produced by the vapor phase deacyloxylation of vicinal hydroxyesters in the presence of a basic material. The co-product carboxylic acid may be reacted with olefins to form additional hydroxyesters.
