邻氯苯腈,是合成染料和医药中间体的重要原料。氨氧化邻氯甲苯直接合成邻氯苯腈是近年来最先进的路线,迄今文献报导的产品收率大都偏低,其根本原因是没有找到理想的催化剂和相应的最佳工艺条件。武汉大学化学系化工教研室首次合成国内外文献未见报导的“新型高效钒-钼催化剂”。该催化剂经实验室小试、中试及生产性试验,证明其具有催化活性高、选择性好、制备简便、成本低廉等显著优点,使邻氯甲苯氨氧化生产邻氯苯腈成品的摩尔收率提高到92%以上。在此基础上,研究者又研究出生产新工艺。该新工艺具有新 Chlorobenzonitrile, is an important raw material for synthetic dyes and pharmaceutical intermediates. The direct synthesis of o-chloronitrochloride from o-chloronitrochloride is the most advanced route in recent years. Up to now, the yield of the products reported in the literature is mostly low. The fundamental reason is that no ideal catalyst and corresponding optimum process conditions have been found. Department of Chemistry, Wuhan University Department of Chemistry for the first time synthesis of domestic and foreign literature has not been reported “new and efficient vanadium - molybdenum catalyst ”. The catalyst by the laboratory test, pilot and production tests proved that it has high catalytic activity, good selectivity, easy preparation, low cost and other significant advantages, the o-chloromethylbenzene oxidation of o-chloronitriles produced Moore income Rate increased to 92% or more. On this basis, the researchers also studied the production of new technology. The new craft is new
