摘要： An improved method for hydrogenating succinonitrile, optionally carrying substituents, to form 2-pyrrolidones, in the liquid phase in the presence of ammonia, using a fixed-bed catalyst wherein the catalyst may be regenerated by successively passing liquid ammonia at 75.degree.-130.degree. C., then hydrogen at 130.degree.-350.degree. C., and then liquid ammonia again at 75.degree.-130.degree. C. over the catalyst.

摘要： An improved process for the preparation of 2-pyrrolidone by the liquid phase hydrogenation of succinonitrile in the presence of a hydrogenation catalyst and ammonia, whereafter the resulting hydrogenation product is hydrolyzed with water. A hydrogenation catalyst in the form of a fixed bed is used, and a liquid phase of succinonitrile and liquid ammonia is passed over the catalyst at a temperature of between 50.degree. and 130.degree. C.

摘要： 2-pyrrolidones are prepared by hydrogenating a succinonitrile in the liquid phase in the presence of ammonia by passing an ammoniacal solution of a succinonitrile over a fixed bed catalyst, particularly of the trickle-phase type, in which the catalyst is nickel on an alkaline support such as calcium hydroxide or calcium carbonate. Attractive yields are achieved without the expense of filtering off and separating used catalyst as in prior procedures.
