amakuru

Icyatsi cyera cyera kugirango gitukura kristu cyangwa pulp. Sodium m-aminobenzene sulfonate yabonetse na sulfonation reaction ya nitrobenzene no kugabanuka. Ikoreshwa mugukora amarangi ya azo hamwe naba farumasi bahuza, reaction, acide, sulfide nandi marangi.

Imikoreshereze: ikoreshwa mugukora amarangi ya azo naba farumasi bahuza imiti, reaction, aside, sulfide nandi marangi.

Inzira yo gutunganya umusaruro: reaction ya sulfonation ya nitrobenzene na fuming acide sulfurike ikorwa kuri 115 ℃, kandi ibicuruzwa byabyitwayemo bitagira aho bibogamiye na alkali y'amazi, hanyuma igisubizo cya sodium ya m-nitrobenzene sulfonate irayungurura. Umuti wagabanutse hamwe nogosha ibyuma nkumusemburo wo kubona m-aminobenzene sulfonate, kandi icyondo cyicyuma cyavanyweho kuyungurura. Akayunguruzo kari m-aminobenzene sulfonate yumunyu. Ongeramo aside sulfurike mu nkono ikuramo aside kugeza igihe impapuro zitukura za congo zihindutse ubururu, kandi ugumane ubushyuhe kuri 70 ℃. Noneho, m-aminobenzene sulfonate slurry iboneka mukuyungurura centrifugation.

Uburozi no kurinda: iki gicuruzwa ni uburozi cyane. Kumira cyangwa kwinjizwa mu ruhu birashobora gutera uburozi bukabije. Nyamara, uburozi bwabwo buri munsi ya aniline, kandi ntibuzatera kanseri. Mugihe cyibikorwa byo kubyaza umusaruro, bigomba gukumirwa byimazeyo kwambara kubwimpanuka cyangwa kumenagura uruhu, ibikoresho byumusaruro bigomba gufungwa kugirango birinde kumeneka, kandi nyirubwite agomba kwambara ibikoresho birinda.

Gupakira no kubika: kubika ahantu hakonje, uhumeka kandi humye, wirinde ubushyuhe, ubushuhe nizuba. Kubika no gutwara ukurikije amabwiriza yerekeye ibintu bifite uburozi.
