    • PURPOSE: An ammoxidation reactive catalyst, and a method of manufacturing dicyano benzene using the same are provided to secure the reaction safety as the reaction heat is able to be easily controlled even when the ammoxidation reaction of xylene is performed in a fixed-bed reactor, and to require no use of dilute gas contrary to the conventional ammoxidation reactive catalyst. CONSTITUTION: An ammoxidation reactive catalyst includes catalyst activation components, and a carrier component containing TiO2 and metal borate. The catalyst activation components include an oxide comprising: vanadium(V); chrome(Cr); molybdenum(Mo), tungsten(W) or both of them; at least one element selected from alkali metals or alkaline earth metals; and manganese(Mn), or another oxide comprising: vanadium(V); chrome(Cr); molybdenum(Mo), tungsten(W) or both of them; at least one element selected from alkali metals and alkaline earth metals; manganese(Mn); and at least one element selected from the group consisting of zinc(Zn), tin(Sn), bismuth(Bi), indium(In), lead(Pb) and antimony(Sb).
    • 目的:提供氨氧化反应催化剂和使用其制备二氰基苯的方法,以确保反应安全性,因为即使在固定床反应器中进行二甲苯的氨氧化反应,反应热也能够容易地控制, 并且不需要使用与常规氨氧化反应催化剂相反的稀释气体。 构成:氨氧化反应催化剂包括催化剂活化组分和含有TiO 2和金属硼酸盐的载体组分。 催化剂活化组分包括氧化物,其包含:钒(V); 铬(Cr); 钼(Mo),钨(W)或它们两者; 至少一种选自碱金属或碱土金属的元素; 和锰(Mn)或另一种氧化物,包括:钒(V); 铬(Cr); 钼(Mo),钨(W)或它们两者; 至少一种选自碱金属和碱土金属的元素; 锰(Mn); 以及选自锌(Zn),锡(Sn),铋(Bi),铟(In),铅(Pb)和锑(Sb)中的至少一种元素。

    • PURPOSE: A manufacturing method of aliphatic alkyl ester is provided to manufacture aliphatic alkylester with high yield by high reactive activity, though oil with the acidity of 2-200 and high contents of free fatty acid, fatty, or a mixture thereof are used as raw material. CONSTITUTION: A manufacturing method of aliphatic alkyl ester comprises: a first step of obtaining crude fatty acid alkylester through the esterification and the trans-esterification of fatty with the acidity of 2-200, oil or mixture thereof, which contains free fatty acid under the condition of C1-5 lower alcohol and no catalyst at 150-250 °C and 5-100 atmosphere; and a second step collecting the crude fatty acid alkylester, and conducting esterification and trans-esterification under the presence of one or more catalyst of MgO and Mg(OH)2 at 150-250 °C and 5-100 atmosphere.
    • 目的:提供脂肪族烷基酯的制造方法,以高反应活性高产率制备脂肪族烷基酯,尽管酸度为2〜200的油和高含量的游离脂肪酸,脂肪或其混合物为原料 材料。 构成:脂肪族烷基酯的制造方法包括:通过酯化反应获得粗脂肪酸烷基酯的第一步骤,其酸度为2〜200的脂肪或其混合物的酯交换,其含有游离脂肪酸 在150-250℃和5-100个大气压下,C 1-5低级醇和无催化剂的条件; 和收集粗脂肪酸烷基酯的第二步,在150-250℃和5-100个气氛下,在一种或多种MgO和Mg(OH)2催化剂存在下进行酯化和酯交换。
