Uhlelo lokusebenza oluthile
Ngokuvamile isetshenziswa ku-organic synthesis futhi iphakathi kwe-anti infertility drug radiomiphene.
Indlela yokukhiqiza:
1. I-P-chlorobenzoyl chloride yalungiswa ukusabela kwe-p-chlorobenzoyl chloride nge-anisole, kulandelwa i-hydrolysis ne-demethylation.
2. Ukusabela kwe-p-chlorobenzoyl chloride nge-phenol: ncibilikisa u-9.4g (0.1mol) we-phenol ku-4ml we-10% yesisombululo se-sodium hydroxide, engeza u-14ml (0.110mol) we-p-chlorobenzoyl chloride dropwise ku-40 ~ 45 ℃. 30min, bese usabela ezingeni lokushisa elifanayo ngo-1H.Kuphole kumazinga okushisa asekamelweni, hlunga futhi yome ukuze uthole u-22.3g we-phenyl p-Chlorobenzoate.Isivuno singu-96%, futhi indawo encibilikayo ingu-99 ~ 101 ℃.

Ingozi yezempilo:
bangela ukucasuka kwesikhumba.Banga ukucasuka kwamehlo okukhulu.Ingabangela ukucasuka komgudu wokuphefumula.
Izinyathelo zokuzivikela:
Hlanza kahle ngemva kokuhlinzwa.
Gqoka amagilavu okuzivikela / izingubo zokuzivikela / izibuko zokuzivikela / imaski yokuzivikela.
Gwema ukuhogela uthuli / intuthu / igesi / intuthu / umhwamuko / isifutho.
Sebenzisa ngaphandle kuphela noma ngokungenisa umoya omuhle.
Impendulo yengozi:
Uma kwenzeka ukungcola kwesikhumba: geza kahle ngamanzi.
Uma kwenzeka ukucasuka kwesikhumba: funa usizo lwezokwelapha.
Khumula izingubo ezingcolile bese uzigeza ngaphambi kokuphinda uzisebenzise
Uma emehlweni: Hlanza ngokucophelela ngamanzi imizuzu embalwa.Uma ugqoka amalensi okuxhumana futhi ukwazi ukuwakhipha kalula, wakhiphe.Qhubeka ushayela.
Uma usazizwa ukucasuka kwamehlo: bona udokotela/ udokotela.
Uma ehogelwe ngephutha: dlulisela umuntu endaweni enomoya ohlanzekile futhi agcine indawo yokuphefumula enethezekile.
Uma uzizwa ungaphilile, shayela isikhungo/udokotela wokukhipha ubuthi emzimbeni
Isitoreji esiphephile:
Gcina endaweni enomoya omuhle.Gcina isitsha sivaliwe.
Indawo yokugcina impahla kufanele ikhiywe.
Ukulahlwa kwemfucuza:
Lahla okuqukethwe / iziqukathi ngokuhambisana nemithetho yendawo.
Izinyathelo zosizo lokuqala:
Ukuhogela: uma uhogeliwe, yisa isiguli emoyeni omusha.
Ukuthinta isikhumba: khumula izingubo ezingcolile bese ugeza isikhumba kahle ngamanzi anensipho namanzi acwebile.Uma uzizwa ungaphilile, bonana nodokotela.
Ukuthintana kwamehlo: hlukanisa amajwabu amehlo bese uwageza ngamanzi agelezayo noma ngosawoti ojwayelekile.Thola usizo lwezokwelapha ngokushesha.
Ukungenisa: Gcoba futhi ungabangeli ukuhlanza.Thola usizo lwezokwelapha ngokushesha.
Iseluleko sokuvikela umhlengi: dlulisela isiguli endaweni ephephile.Bonana nodokotela.Bonisa udokotela osesiza le manuwali yokuphepha kwamakhemikhali.
