Imininingwane Yomkhiqizo

Omaka bomkhiqizo

I-2-methyl -4-(trifluoromethyl) i-thiazole-5-carboxylic acid iyinhlanganisela ye-organic ene-chemical formula C6H4F3NO2S.

I-compound inalezi zimpawu ezilandelayo:
1. Ukubukeka: ikristalu engenambala noma i-crystalline powder emhlophe.
2. Iphuzu elincibilikayo: cishe ku-70-73°C.
3. ukunyibilika: kuncibilika kwezinye izinyibilikisi eziphilayo, njenge-ethanol, i-dimethyl sulfoxide ne-chloroform, inyibilika kancane emanzini.

Ukusetshenziswa okuyinhloko kwe-2-methyl -4-(trifluoromethyl) thiazole-5-carboxylic acid kufaka phakathi:
1. inkundla yezemithi: njengesidakamizwa esiphakathi nendawo, ingasetshenziselwa ukuhlanganiswa kwezinhlobonhlobo zemithi.
2. Insimu yezibulala-zinambuzane: evame ukusetshenziswa ekuhlanganiseni izibulala-zinambuzane ezintsha, izibulala-zinambuzane nezinye izibulala-zinambuzane.

I-2-methyl -4-(trifluoromethyl) thiazole -5-carboxylic acid izindlela ngokuyinhloko yilezi ezilandelayo:
1. ukusabela kwe-amide ne-formaldehyde kwe-condensation: i-formic acid ne-ethyl ester condensation ukuze kukhiqizwe i-acid anhydride, bese kuba nokusabela kwe-amine condensation ukuthola umkhiqizo ohlosiwe.
2. Ukusabela kwe-Hydrogenation ngaphansi kwe-acid catalysis: I-2-methyl -4- (trifluoromethyl) i-thiazole-5-carboxylic acid isabela nge-hydrogen ngaphansi kwe-acid catalysis ukuze ithole umkhiqizo ohlosiwe.

Mayelana nolwazi lokuphepha, idatha ye-toxicological nezokuphepha ye-2-methyl -4-(trifluoromethyl) thiazole-5-carboxylic acid ayivamile ukubikwa, ngakho-ke kuyadingeka ukuthatha izinyathelo zokuphepha ezithile ngesikhathi sokusebenza kwaselabhorethri, njengokugqoka izibuko zokuzivikela namagilavu, ukuqinisekisa ukuthi umsebenzi wokuhlola wenziwa endaweni enomoya omuhle. Ngaphezu kwalokho, i-compound ingase idle futhi icasule, futhi ukunakekelwa kufanele kuthathwe ukuze kuvinjelwe ukuthintana nesikhumba kanye nokuhogela. Ngesikhathi sokusetshenziswa nokugcinwa, izinqubo zokuphepha kwamakhemikhali kufanele zilandelwe futhi zigcinwe endaweni eyomile, engenamoya futhi emnyama. Lapho uphatha futhi ulahla lesi sakhiwo, landela imithetho yendawo efanele kanye nemihlahlandlela yokusebenza ephephile. Uma uhlangana nento ngephutha, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha.
