Isingeniso

I-Trifluoromethylbenzaldehyde (eyaziwa nangokuthi i-TFP aldehyde) iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-trifluoromethylbenzaldehyde:

 

Ikhwalithi:

- Ukubukeka: I-Trifluoromethylbenzaldehyde iwuketshezi olungenambala ukuya kokuphuzi olunephunga le-benzaldehyde.

- Ukunyibilika: Iyancibilika kuzincibilikisi ze-ether ne-ester, inyibilika kancane kuma-aliphatic hydrocarbons, kodwa ayincibiliki emanzini.

 

Sebenzisa:

- Ocwaningweni lwamakhemikhali, lungasetshenziswa ukuhlanganisa amanye amakhompiyutha nezinto zokwakha.

 

Indlela:

I-Trifluoromethylbenzaldehyde ngokuvamile ilungiswa ngokusabela kwe-benzaldehyde ne-trifluoroformic acid. Ngesikhathi sokusabela, ngokuvamile kwenziwa ngaphansi kwezimo ze-alkali ukuze kube lula ukusabela. Indlela ethile yokuhlanganisa ngokuvamile ingachazwa ngokuningiliziwe ezincwadini noma kumalungelo obunikazi we-organic synthesis.

 

Ulwazi Lokuphepha:

- I-Trifluoromethylbenzaldehyde iyinhlanganisela yezinto eziphilayo, ngakho-ke kufanele kuthathwe izinyathelo zokuqapha lapho uyisebenzisa, futhi imininingwane yokusebenza ehambisanayo kufanele ilandelwe.

- Ukuthinta isikhumba noma ukuhogela umhwamuko waso kungase kubangele ukucasuka nokulimala emzimbeni womuntu, futhi ukuthintana ngokuqondile nokuhogela kufanele kugwenywe lapho usebenza elabhorethri.

- Uma uthintana noma uhogela umoya, hlambulula ngokushesha indawo ethintekile ngamanzi ahlanzekile futhi ufune usizo lwezokwelapha.

- Lapho ugcina futhi uphatha, inhlanganisela kufanele igcinwe esitsheni esingangeni moya, kude nomlilo nomoya-mpilo, ukugwema ingozi yomlilo nokuqhuma.
