Isicelo esithile
Ngokuvamile isetshenziswa ekwakhiweni kwezinto eziphilayo futhi iyisithako esiphakathi kwesidakamizwa sokulwa nokungabi nabantwana i-radiomiphene.
Indlela yokukhiqiza:
1. I-P-chlorobenzoyl chloride yalungiswa ngokusabela kwe-p-chlorobenzoyl chloride ne-anisole, kulandelwe yi-hydrolysis kanye ne-demethylation.
2. Ukusabela kwe-p-chlorobenzoyl chloride ne-phenol: ncibilikisa u-9.4g (0.1mol) we-phenol ku-4ml yesisombululo se-sodium hydroxide esingu-10%, engeza u-14ml (0.110mol) we-p-chlorobenzoyl chloride ngokuwa phansi ku-40 ~ 45 ℃, uyifake kungakapheli imizuzu engama-30, bese usabela ekushiseni okufanayo ihora eli-1. Phola kuze kufike ekushiseni kwegumbi, hlunga bese womisa ukuze uthole u-22.3g we-phenyl p-Chlorobenzoate. Isivuno singama-96%, kanti iphuzu lokuncibilika lingu-99 ~ 101 ℃.

Pholisa ekushiseni kwegumbi, hlunga bese womisa ukuze uthole ama-22.3g e-phenyl p-Chlorobenzoate. Isivuno singama-96%, kanti iphuzu lokuncibilika lingu-99 ~ 101℃.
Ingozi yempilo:
kubangela ukucasuka kwesikhumba. Kungabangela ukucasuka okukhulu kwamehlo. Kungabangela ukucasuka kwendlela yokuphefumula.
Izinyathelo zokuzivikela:
Hlanza kahle ngemva kokuhlinzwa.
Gqoka amagilavu okuzivikela / izingubo zokuzivikela / izibuko zokuzivikela / imaski yokuzivikela.
Gwema ukuhogela uthuli / intuthu / igesi / intuthu / umhwamuko / isifutho.
Sebenzisa kuphela ngaphandle noma ngokungenisa umoya okuhle.
Impendulo yengozi:
Uma isikhumba singcolile: geza kahle ngamanzi.
Uma kwenzeka ukucasuka kwesikhumba: funa usizo lukadokotela.
Khumula izingubo ezingcolile bese uzigeza ngaphambi kokusebenzisa kabusha
Uma ungena emehlweni: Hlanza ngokucophelela ngamanzi imizuzu embalwa. Uma ugqoka ama-contact lens futhi ungakwazi ukuwakhipha kalula, wakhiphe. Qhubeka nokuwahlanza.
Uma usazizwa ucasuka emehlweni: bona udokotela/udokotela.
Uma kwenzeka ukuphefumula ngengozi: dlulisela umuntu endaweni enomoya omusha futhi ugcine isimo sokuphefumula esikhululekile.
Uma uzizwa ungaphilile, shayela isikhungo sokukhipha ubuthi emzimbeni/udokotela
Isitoreji esiphephile:
Gcina endaweni enomoya omuhle. Gcina isitsha sivaliwe.
Indawo yokugcina izinto kumele ikhiywe.
Ukulahlwa kwemfucuza:
Lahla okuqukethwe/izitsha ngokuhambisana nemithetho yendawo.
Izindlela zosizo lokuqala:
Ukuphefumula: uma uphefumula, hambisa isiguli emoyeni omusha.
Ukuthintana nesikhumba: khumula izingubo ezingcolile bese ugeza isikhumba kahle ngamanzi anensipho namanzi acwebile. Uma uzizwa ungaphilile, bona udokotela.
Ukuthintana kwamehlo: hlukanisa izinkophe bese ugeza ngamanzi agobhozayo noma usawoti ojwayelekile. Funa usizo lwezokwelapha ngokushesha.
Ukungena: geza ikhanda futhi ungabangeli ukuhlanza. Funa usizo lwezokwelapha ngokushesha.
Iseluleko sokuvikela umhlengi: dlulisela isiguli endaweni ephephile. Xhumana nodokotela. Bonisa udokotela okule ndawo le ncwadi yezobuchwepheshe yokuphepha kwamakhemikhali.
