在V_2O_5、Sb_2O_3、Bi_2O_3、Fe_2O_3、K_2O/Al_2O_3催化剂上邻二甲苯的氨氧化

Ammoxidation of O-Xylene Over V_2O_5,Sb_2O_3,Bi_2O_3,Fe_2O_3,K_2O/Al_2O_3 Catalysts

本文论述了邻二甲苯氨氧化合成邻苯二甲腈的最佳工艺条件,载在高温热处理的三氧化二铝上的 V_2O_s、Sb_2O_3、Bi_2O_3、Fe_2O_3、K_2O 催化剂,对生成邻苯二甲腈表现出良好的活性及选择性,其选择率>95%。催化剂的酸度是一个关键因素.

An actual operating condition for the Synthesis of phthalonitrile by ammoxidation of O-Xylene is discussed.The mixing of V、Sb、Fe、K Oxides Catalysts Supported alumina heated at a high temperature Shws a good activity and selectivity towards the formation of phthalonitrile.The selecti- vity is>95%.The Catalyst acidity is a key factor.
