4-Chloro-4′-hydroxybenzophenone (CAS# 42019-78-3)
| Amakhodi Engozi | R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile. |
| Incazelo Yokuphepha | I-S24/25 - Gwema ukuthintana nesikhumba namehlo. I-S37/39 – Gqoka amagilavu afanelekile kanye nokuvikela iso/ubuso S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S36 – Gqoka izingubo ezifanele zokuzivikela. |
| Ikhodi ye-HS | 29144000 |
| Inothi Lengozi | Iyacasula |
Isingeniso
I-4-Chloro-4′-hydroxybenzophenone iyinhlanganisela yezinto eziphilayo. Okulandelayo ulwazi mayelana nezakhiwo, ukusetshenziswa, izindlela zokulungiselela, nokuphepha kwenhlanganisela:
Ikhwalithi:
Ukubukeka: I-4-Chloro-4'-hydroxybenzophenone i-crystalline emhlophe noma i-crystalline powder.
Ukunyibilika: kuncibilika ku-ethanol, i-dimethylformamide ne-chloroform, inyibilika kancane ku-ether ne-carbon chloride.
Sebenzisa:
I-4-Chloro-4′-hydroxybenzophenone ingasetshenziswa njengendawo emaphakathi ku-organic synthesis ukuze kuhlanganiswe ezinye izinhlanganisela eziphilayo.
Indlela:
I-4-Chloro-4′-hydroxybenzophenone ingatholakala ngokufaka esikhundleni se-sodium sulfite ne-sodium thiothioreagent (isb, i-phthathiadine) ye-sodium sulfite. Indlela eqondile yokulungiselela imi kanje:
I-phthamethamidine incibilika ku-dimethylformamide, i-hydroxyacetophenone yengezwa kwisixazululo sokusabela, ngemva kwesikhathi esithile sokusabela, amanzi angezwa, futhi umkhiqizo ukhishwa, womiswe futhi uhlanganiswe ne-chloroform ukuze uthole umkhiqizo ohlosiwe.
Ulwazi Lokuphepha:
I-4-Chloro-4′-hydroxybenzophenone izinzile ngaphansi kwezimo ezijwayelekile. Kodwa-ke, ukuxhumana nama-oxidizing agents aqinile kufanele kugwenywe.
Izinto zokuzivikela ezifanele ezifana namagilavu, izibuko, nezingubo zokugqoka kufanele zigqokwe lapho kwenziwa ukuhlinzwa okunjalo.
Kufanele igcinwe kude nezinto ezivuthayo nemithombo yokushisa, futhi igcinwe esitsheni esingangenisi umoya ukuze kugwenywe ukuchayeka emoyeni.
Sicela ulahle inkomba kanye nemfucuza yayo ngendlela efanele, ngokulandela imithetho yendawo yokulawulwa kukadoti.
