Claims (1)
2,2'-디클로로니트로벤젠을 밀폐 반응조에 주입하고, 알카리 용액을 투입한 후 분산제와 유기용매를 주입하여 분산시키고 생성된 반응혼합물에 톨루엔을 주입하여 용해시킨 다음 수첨 반응 촉매를 투입하고 불활성 가스를 0.01kg/cm2-10kg/cm2의 압력으로 되게 주입하고 40-90℃의 반응온도에서 수소화 압력을 0.02kg/cm2로 부터 12kg/cm2까지의 범위내에서 단계적으로 승압시켜 수소첨가 반응시켜 2,2'-디클로로하이드라조벤젠을 제조하는 2,2'-디클로로하이드라조벤젠의 제조방법.2,2'-dichloronitrobenzene was injected into a sealed reactor, an alkali solution was added, a dispersant and an organic solvent were injected and dispersed, and toluene was injected and dissolved in the resulting reaction mixture, followed by adding a hydrogenation catalyst and an inert gas. Is added at a pressure of 0.01kg / cm 2 -10kg / cm 2 and hydrogenated by increasing the hydrogenation pressure stepwise within a range from 0.02kg / cm 2 to 12kg / cm 2 at a reaction temperature of 40-90 ° C. A method for producing 2,2'-dichlorohydrazobenzene by reacting to produce 2,2'-dichlorohydrazobenzene.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
