Isicelo esithile
Izithako zokubulala izinambuzane; Isetshenziswa njenge-intermediate ye-puma, i-Gaicao esebenza kahle kakhulu, i-jingwensha, i-jingquizalofop, i-alkyne ester kanye neminye imithi yokubulala ukhula
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 ℃.
Ukwelashwa okuphuthumayo kokuvuza
Izindlela zokuvikela, imishini yokuvikela kanye nezinqubo zokulahla eziphuthumayo zabasebenzi:
Kunconywa ukuthi abasebenzi bezokwelapha eziphuthumayo bagqoke imishini yokuphefumula umoya, izingubo ezivimbela ukuminyana kanye namagilavu amelana namafutha enjoloba.
Ungathinti noma unqamule ukuchitheka.
Yonke imishini esetshenziswa ngesikhathi sokusebenza kufanele ibekwe phansi.
Nquma umthombo wokuvuza ngangokunokwenzeka. Susa yonke imithombo yokushisa.
Indawo yesixwayiso kufanele ibekwe ngokwendawo ethintwe ukugeleza koketshezi, umusi noma ukusabalala kothuli, futhi abasebenzi abangabalulekile kufanele bathuthelwe endaweni yokuphepha besuka emoyeni naphezulu.
Izindlela zokuvikela imvelo: zivimbela ukuvuza ukuze kugwenywe ukungcoliswa kwemvelo. Vimbela ukuvuza ukuthi kungangeni emiseleni yamanzi angcolile, emanzini angaphezulu kanye namanzi angaphansi komhlaba.
Izindlela zokugcina nokususa amakhemikhali avuzayo nezinto zokulahla ezisetshenziswayo:
Ukuvuza okuncane: qoqa uketshezi oluvuzayo esitsheni esivalekayo ngangokunokwenzeka. Munca ngesihlabathi, i-activated carbon noma ezinye izinto ezingasebenzi bese udlulisela endaweni ephephile. Ungawuhlanzi ungene epayipini lokuthuthwa kwamanzi.
Ukuvuza okukhulu: yakha i-dike noma umbe umgodi wokwamukela. Vala ipayipi lokukhipha amanzi. Igwebu lisetshenziselwa ukumboza ukuhwamuka. Dlulisela emotweni yethangi noma kumqoqi okhethekile onepompo engaqhumi, uvuselele noma uthuthe uye endaweni yokwelapha imfucuza ukuze ilahlwe.
Imishini yokuzivikela yomuntu siqu:
Ukuvikelwa kokuphefumula: lapho ukugcwala emoyeni kudlula okujwayelekile, gqoka imaski yegesi yokuhlunga (imaski eyingxenye). Uma usindisa noma uphuma esimweni esiphuthumayo, kufanele ugqoke umshini wokuphefumula umoya.
Ukuvikela izandla: gqoka amagilavu amelana namafutha enjoloba.
Ukuvikela amehlo: gqoka amehlo okuvikela amakhemikhali.
Ukuvikelwa kwesikhumba nomzimba: gqoka izingubo zokusebenza ezilwa noshevu.
