摘要： Allyl alcohol is produced in simple and economical fashion from propylene and oxygen by reacting propylene, oxygen and acetic acid over a palladium-containing catalyst in the presence of water; condensing the reaction product to form a condensate containing allyl acetate, acetic acid and water; treating the condensate with an acid catalyst and separating the resulting product by distillation into a head product consisting essentially of an allyl acetate/allyl alcohol/water azeotrope and into a sump product consisting essentially of acetic acid, allyl alcohol and water; recycling the head product to the acid catalyst stage; separating the sump product in a second distillation into an allyl alcohol/water head product and into a second sump product consisting essentially of acetic acid and water and recycling this sump product to the initial reaction.

摘要： Process for continuous production of propylene oxide (FIG. 1) from propylene and aqueous hydrogen peroxide. The aqueous hydrogen peroxide is first reacted with propionic acid in the presence of acid catalyst to form perpropionic acid (1). The perpropionic acid is taken up by extraction in benzene (5, 18) and following drying of the benzene solution (21), the perpropionic acid in the solution is reacted with propylene (24) for oxidation of the propylene to propylene oxide and conversion of the perpropionic acid back to propionic acid. The reaction mixture is worked up to separate propylene oxide, propionic acid and benzene (30, 32, 37, 39), and the latter two are recycled. In the benzene extraction (5, 18), an aqueous raffinate (7) is formed containing hydrogen peroxide and acid catalyst. The aqueous raffinate can be divided into a stream which is recycled to the propionic acid reactor (1), and a second stream which can be distilled to remove water with the concentrate being recycled to the propionic acid reactor (1).
