Abstract: 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.

Abstract: AN IMPROVED PROCESS FOR THE PREPARATION OF N-ALKYL SUBSTITUTED LACTAMS USEFUL AS SOLVENTS BY HEATING A CYANHYDRIN REPRESENTED BY THE FORMULA HO(CH2)NCN WHEREIN N IS AN INTEGER OF 3 TO 5 INCLUSIVE TOGETHER WITH AN ALCOHOL REPRESENTED BY THE FORMULA ROH WHEREIN R REPRESENTS AN AKYL GROUP HAVING 1 TO 4 CARBON ATOMS AT A TEMPERATURE OF 250*C. TO 400*C. UNDER PRESSURE. THE PRESENT PROCESS GIVES AN IMPROVED YIELD OF THE DESIRED PRODUCT AT A LOW COST AS COMPARED WITH THE PRIOR ART PROCESS. THE PROCESS CAN BE ADVANTAGEOUSLY MODIFIED. ONE MODIFICATION CONSISTS IN THE PROCESS OF A SPECIFIC CATALYST. ANOTHER MODIFICATION CONSISTS IN THE PROCESS IN WHICH AS LEAST A PART OF THE BY-PRODUCTS ARE RECYCLED IN THE REACTION SYSTEM. STILL ANOTHER MODIFICATION CONSISTS IN THE PROCESS IN WHICH THE REACTION IS CONDUCTED IN THE PRESENCE OF WATER, THE WATER BEING ADDED AT THE TIME OF INITIATION OF THE REACTION. SUCH MODIFICATIONS GIVE A FURTHER IMPROVED YIELD OF THE DESIRED PRODUCT.
