摘要:
A method for preparing tertiary butyl alcohol wherein a feedstock comprising a solvent solution of tertiary butyl hydroperoxide in tertiary butyl alcohol or a mixture of tertiary butyl alcohol with isobutane is charged to a hydroperoxide decomposition reaction zone containing a catalytically effective amount of a hydroperoxide decomposition catalyst consisting essentially of alumina having chromium deposited thereon and is brought into contact with the catalyst in liquid phase under hydroperoxide decomposition reaction conditions to convert the tertiary butyl hydroperoxide to decomposition products, principally tertiary butyl alcohol.

摘要:
57 Alkanols are reacted with carbon monoxide to form carboxylic acids at elevated temperature and pressure in the presence of a halide-promoted solid carbon catalyst. High yields and selectivity (especially of acetic acid from methanol) togetherwith extended catalyst life are achieved as a result of conducting the carbonylation in the presence of at least 1 ppm of cobalt, ruthenium, iron, nickel, rhodium, palladium, osmium, iridium or platinum. These transition metals can either be added as soluble compounds thereof, or can be derived from the walls of a cobalt or nickel alloy reactor.
