我要合成是是甲基苯并三唑钠盐,现在文献有2条工艺路线,我不知道走哪条,希望指点,第1条是邻硝基氯苯与肼(水合肼)直接合成,可是产物是1一羟基苯并三唑,而且也不是"甲基苯并三唑钠盐"!不知道原料换成邻硝基氯甲苯的话,会不会影响工艺路线,第2条是甲基苯并三唑,可它是高压法,邻硝基苯胺重氮化,可是200多度,4Mpa,我合成不是中试,不需要反应釜,玻璃器皿承受不住的吧?那请问怎么办?
另外CAS号13590-97-1的合成路线谁知道,最好带参考文献,谢谢!帮忙CROSSFIRE查下!

甲基在什么位置？？表述的不太清楚。文献可以自己查的。

用甲基邻苯二氨做原料重氮化关环呢

Abstract

Effluent limits, pretreatment stds. and performance stds. for new and existing facilities that manuf. pesticide active ingredients are proposed, under the Federal Clean Water Act. The manufacturers are categorized as those who make metalloorg. pesticide chems. (contg. As, Cd, Cu, or Hg) and those who make org. pesticide chems. (including organotin compds.). Tables are given for active ingredient (94) limitations (daily max. and monthly av.) under best available technol. economically achievable and pretreatment stds. for existing sources, new source performance stds. and pretreatment stds. for new sources, and anal. methods (for 94 compds.). Addnl., effluent limitations (daily max. and monthly av.)for priority pollutants are proposed.
