烟酸合成工艺的改革
The Modification of Synthetic Process for Nicotinic Acid
-
摘要: 本文研究了以对一氨基苯酚为起始原料,先合成6-羟基喹啉;再经氧化、加热脱羧合成烟酸的两项重要工艺改革。两项改革均具有简化流程、节省原料、提高收率、经济效益显著等优越性。Abstract: This thesis discusses P-aminophenol as primary raw materials which was first synthesized6-hydroxyl Quinoline and then were made into Oxidation, Decarboxylate and synthetisizedNicotinic acid. These two techniques have simplified the Process, economized raw
