Abstract: AN IMPROVED PROCESS FOR THE PRODUCTION OF LACTONES HAVING SIX TO THIRTEEN RING MEMBERS AND ISOBUTYRIC ACID BY REACTION OF A CYCLIC KETONE HAVING FROM FIVE TO TWELVE RING MEMBERS AND ISOBUTYRIC ACID BY REACTION OF A CYCLIC KETONE HAVING FROM FIVE TO TWELVE RING MEMBERS AND ISOBUTYRALDEHYDE WITH MOLECULAR OXYGEN OR A GAS CONTAINING THE SAME, THE IMPROVEMENT CONSISTING IN CARRYING OUT THE REACTION WITHOUT USING A CATALYST. LACTONES ARE USED IN THE PRODUCTION OF POLYESTOR.

Abstract: Manufacture of carboxamides by the addition of water to nitriles in the presence of a copper-containing and magnesium silicatecontaining catalyst which has been treated with a reducing gas. The carboxamides obtained by the process of the invention are valuable starting materials for the manufacture of solvents, flocculating agents, crosslinking agents, pesticides, plant protectants, textile auxiliaries such as levelling agents, waterproofing agents, foam stabilizers and detergents.

Abstract: PROCESS FOR PRODUCING LACTIC ACID BY THE HYDROLYSIS OF LACTIC ACID NITRATE IN WHICH THE LACTICE ACID NITRATE IS REACTED WITH MORE THAN TWICE ITS WEIGHT OF WATER. IT HAS BEEN FOUND THAT HIGH YEILDS OF LACTICE ACID CAN BE OBTAINED EITHER FROM PURE LATICE ACID NITRATE OR FROM THE REACTION PRODUCT CONTAINING IMPURITIES AS WELL AS LACTIC ACID NITRATE.
