  • Patent number: 4490532
    Abstract: Hydrogen chloride is passed into p-xylene and acetaldehyde to form bis-1-chloroethyl ether; the latter is converted to 2-(1-chloroethyl)-1,4-dimethylbenzene by the action of sulfuric acid and hydrogen chloride. Alkali metal hydrogen sulfide in aqueous methanol or ethanol converts the 2-(1-chloroethyl)-1,4-dimethylbenzene to alpha,2,5-trimethylbenzenemethanethiol; the sodium salt of the latter reacted with 2-chloropyridine-1-oxide yields 2-[1-(2,5-dimethylphenyl)ethylthio]pyridine-1-oxide which is then oxidized with hydrogen peroxide and alkali metal tungstate or tungstic acid to form 2-[1-(2,5-dimethylphenyl)ethylsulfonyl]pyridine-1-oxide.

  • 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.
