    摘要: A process for increasing the amount of isolatable products in a by-product stream generated in the production of 1,6 hexanediol includes combining the by-product stream with water to form a combination of the water and the by-product stream; and reacting the combination at a temperature between about 250.degree. C. to about 400.degree. C. at a pressure from about 1,000 psig to about 3,000 psig to form one or more reaction products.

    摘要: Disclosed is a method for hydrating a cycloolefin, in which the hydration is conducted in a reaction system comprising a continuous aqueous phase including water and a crystalline aluminosilicate catalyst suspended therein and an oil phase including a cycloolefin, while dispersing the oil phase as globules having a specific diameter. By the method of the present invention, not only can a cyclic alcohol be produced at high selectivity and in high yield, but the activity of the catalyst can also be stably maintained at a high level for a prolonged period of time, and the produced cyclic alcohol can be readily separated.
