| Amakhodi Engozi | R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. I-R68 – Ingozi engaba khona yemiphumela engenakuhlehliswa R43 - Ingabangela ukuzwela ngokuthinta isikhumba R40 – Ubufakazi obuncane bomphumela we-carcinogenic R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile. |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.) S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. S36 – Gqoka izingubo ezifanele zokuzivikela. |

Isingeniso
I-2-Amino-4-nitrophenol iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:
Ikhwalithi:
I-2-Amino-4-nitrophenol iyinto eqinile enamakristalu aphuzi ngokubukeka. Inokuncibilika okuphansi ekamelweni lokushisa, iyancibilika kuzincibilikisi eziphilayo njenge-ether ne-benzene, futhi inyibilika kancane emanzini. Ine-asidi eqinile futhi i-oxidizing kakhulu.
Sebenzisa:
I-2-Amino-4-nitrophenol isetshenziswa kakhulu njengempahla eluhlaza odayi nezingulube. Ingasetshenziselwa ukulungisa odayi ababonakala bephuzi noma osawolintshi, futhi ingasetshenziselwa ukulungisa ama-colorants e-pigment namapende.
Indlela:
I-synthesis ye-2-amino-4-nitrophenol ingatholakala ngokusabela kwe-phenol ne-nitric acid ukwakha i-p-nitrophenol, bese ngokusabela ngamanzi e-ammonia ukwenza i-2-amino-4-nitrophenol. Umzila othize wokuhlanganisa kanye nezimo zokusabela zizohluka, futhi indlela efanele yokuhlanganisa ingakhethwa ngokuya ngezidingo.
Ulwazi Lokuphepha:
I-2-Amino-4-nitrophenol iyinhlanganisela ecasulayo futhi enobuthi, futhi ukuchayeka noma ukuhogela uthuli lwayo kungase kubangele ukucasuka emehlweni, isikhumba, kanye nomgudu wokuphefumula. Izinto zokuzivikela ezifanele kufanele zigqokwe lapho usebenzisa noma uphathwa futhi ukuthintana ngokuqondile kufanele kugwenywe. Kungase futhi kube yingozi emvelweni, futhi imfucuza kufanele ilahlwe ngendlela efanele futhi kulandelwe izinqubo ezifanele zokusebenza zokuphepha.
