2 5-bis(trifluoromethyl)benzoyl chloride (CAS# 393-82-8)

Isingeniso

I-2,5-bis(trifluoromethyl)benzoyl chloride iyinhlanganisela yezinto eziphilayo enefomula yamakhemikhali ethi C9H2ClF6O. Iwuketshezi olungenambala olunephunga elimnandi. Okulandelayo incazelo eningiliziwe yemvelo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha lwe-2,5-bis(trifluoromethyl)benzoyl chloride:

Imvelo:

-Ukubukeka: uketshezi olungenambala

Isisindo samangqamuzana: 250.56g/mol

-Indawo yokubilisa: 161-163°C

-Indawo yokuncibilika: -5°C

-Ukuminyana: 1.51g/cm³

-I-Refractive Index: 1.4450(20°C)

Sebenzisa:

I-2,5-bis(trifluoromethyl)benzoyl chloride iyi-reagent ebalulekile futhi isetshenziswa kabanzi ekuphenduleni okuningi kwe-organic synthesis. Ingasetshenziselwa ukuhlanganisa izinhlanganisela ezinemisebenzi ehlukahlukene, njengama-ketone, ama-ether, ama-esters, ama-azides, njll. Ingasetshenziswa futhi njengendawo emaphakathi ekuhlanganiseni kwezidakamizwa.

Indlela Yokulungiselela:

Ngokuvamile, ukulungiswa kwe-2,5-bis(trifluoromethyl)benzoyl chloride kungatholakala ngokusabela i-2,5-bis-trifluoromethylbenzoic acid ngokweqile kwe-thionyl chloride (SO2Cl2). Ukusabela kudinga ukwenziwa ezingeni lokushisa elifanele, futhi ukoma nokwelashwa kokuhlanza igesi kuyadingeka.

Ulwazi Lokuphepha:

I-2,5-bis(trifluoromethyl)benzoyl chloride iyinhlanganisela ecasulayo engase icasule amehlo, isikhumba, kanye nendlela yokuphefumula. Kufanele kuqashelwe ukugwema ukuthintana ngesikhathi sokusetshenziswa kanye nokuqinisekisa ukuthi kusetshenzwa endaweni enomoya omuhle. Gwema ukuhogela umhwamuko wayo futhi ugweme ukuwugwinya noma ukuthinta izitho zangaphakathi. Gqoka amagilavu ​​okuzivikela afanelekile, izibuko nezingubo zokuzivikela ngesikhathi sokusebenzisa. Uma uthintana ngephutha, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha. Lapho isetshenziswa futhi igcinwa, kufanele ilandele izinqubo zokuphepha ezifanele.
