Benzenediam NIST cov ntaub ntawv tshuaj siv thiab cov txheej txheem hluavtaws ntawm 1, 3-phenylenediamine (108-45-2).Cov khoom siv tshuaj muaj xim tsis muaj koob zoo li crystal.Soluble hauv dej, ether thiab ethanol.

Feem ntau yog siv los ua cov xim nruab nrab thiab epoxy resin curing tus neeg sawv cev rau azo dye thiab acazine dye intermediate, feem ntau yog siv rau hauv kev tsim cov tanning RN, yooj yim txiv kab ntxwv, yooj yim xim av G, ncaj tanning G thiab lwm yam dyes, thiab siv raws li plaub dye, nyob rau hauv Nyiv. , azo dye noj ntawm m-phenylenediamine account rau 90% ntawm tag nrho cov noj.Nws kuj yog siv los ua tus neeg saib xyuas ntawm epoxy resin, coagulant txhawb cov cement, thiab siv rau hauv cov plaub hau zas, mordant, colour agent thiab lwm yam. analytical reagent, resin curing agent thiab polymer inhibitor, kuj siv rau hauv kev sib txuas ntawm dyes rau kev txiav txim siab spectrophotometric ntawm nitrite, kev txiav txim siab ntawm bromate, bromide, chromate, ozone, kub, tooj liab, dichromate, hlau, oxygen thiab platinum, kev txiav txim siab ntawm cov tshuaj chlorine, Chromium, iridium, nitrite thiab palladium.Production method: nitrobenzene yog nitrated los ntawm tov kua qaub rau hauv m-dinitrobenzene, o-dinitrobenzene, p-dinitrobenzene sib tov, thiab ces los ntawm sodium sulfite thiab kua alkali refining m-dinitrobenzene, ibd ces hlau hmoov txo los yog hydrogenation txo mus rau m-phenylenediamine.
