Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Amakhodi Engozi R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile.
R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba.
Incazelo Yokuphepha S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
S27 – Khumula ngokushesha zonke izingubo ezingcolile.
S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu ​​kanye nokuvikela iso/ubuso.

Isingeniso

I-M-trifluoromethoxyphenol. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha:

 

Ikhwalithi:

I-M-trifluoromethoxyphenol iwuketshezi oluyicrystalline olumhlophe oluncibilika kuzincibilikisi zemvelo ezifana nama-ether nama-alcohol, kodwa ezingancibiliki emanzini. I-acidic kakhulu futhi i-oxidizing.

 

Ukusetshenziswa: Ingasetshenziswa futhi njengesengezo kuma-antioxidants, ama-flame retardants, nama-photoinitiators, phakathi kwabanye.

 

Indlela:

I-M-trifluoromethoxyphenol ingalungiswa nge-trifluoromethylation ye-cresol. Isinyathelo esiqondile ukusabela i-cresol ne-trifluoromethane (i-ejenti ye-fluorinating) phambi kwe-ejenti esebenzayo ukuze kukhiqizwe i-m-trifluoromethoxyphenol.

 

Ulwazi Lokuphepha:

I-M-trifluoromethoxyphenol ayibangeli umonakalo omkhulu emzimbeni womuntu ngaphansi kwezimo ezijwayelekile zokusetshenziswa. Kuyikhemikhali futhi kufanele kuqashelwe ukugwema ukuhogela uthuli noma ukuthintana kwesikhumba. Izinto zokuzivikela ezifanele ezifana namagilavu ​​okuzivikela nezibuko zamehlo kufanele zigqokwe lapho zisetshenziswa. Lapho ugcina futhi uphatha, imisebenzi efanele yokuphepha kanye nemithethonqubo kufanele kubhekwe, ukuthintana nemithombo yokuthungela kufanele kugwenywe, futhi ukuxubana nezinto ezifana nama-oxidants nama-asidi aqinile kufanele kugwenywe. Uma kwenzeka ingozi efana nokuvuza, kufanele kuthathwe izinyathelo eziphuthumayo ezifanele ukubhekana nayo futhi kufanele kuboniswane nochwepheshe.
