Omaka bomkhiqizo

Amakhodi Engozi R36/38 – Ukucasuka emehlweni nasesikhunjeni.
R45 – Ingabangela umdlavuza
Incazelo Yokuphepha S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
S36 – Gqoka izingubo ezifanele zokuzivikela.
S53 – Gwema ukuchayeka – thola imiyalelo ekhethekile ngaphambi kokuyisebenzisa.
S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.)

Isingeniso

Sudan IV. udayi wemvelo wokwenziwa onegama lamakhemikhali elithi 1-(4-nitrophenyl) -2-oxo-3-methoxy-4-nitrogenous heterobutane.

 

Sudan IV. i-crystalline powder ebomvu encibilika kuzincibilikisi zemvelo ezifana ne-ethanol, i-dimethyl ether ne-acetone, futhi engancibiliki emanzini.

 

Indlela yokulungiselela udayi waseSudan IV. itholakala ikakhulukazi ngokusabela kwe-nitrobenzene nge-nitrogenous heterobutane. Izinyathelo eziqondile ezokuqala kusabele i-nitrobenzene nge-nitrogenous heterobutane ngaphansi kwezimo ezine-acidic ukuze kukhiqizwe inhlanganisela eyandulela i-Sudan IV. Khona-ke, ngaphansi kwesenzo se-ejenti ye-oxidizing, izinhlanganisela ze-precursor zifakwa i-oxid ku-Sudan IV yokugcina. umkhiqizo.

Kungase kucasule isikhumba, amehlo, nendlela yokuphefumula futhi kufanele kusetshenziswe nezinto zokuzivikela ezifanele njengamagilavu, izibuko, namamaski. Udayi waseSudan IV. ube nobuthi obuthile futhi kufanele ugwenywe lapho uthintana ngqo noma ukumunywa. Lapho usebenzisa futhi ugcina, kufanele kuqashelwe ukugwema ukuthintana nama-oxidants noma izinto ezivuthayo.
