Uhlelo lokusebenza oluthile
Izibulala-zinambuzane;Isetshenziswa njengengxenye ephakathi ye-puma, ukusebenza kahle okuphezulu kwe-Gaicao, i-jingwensha, i-jingquizalofop, i-alkyne ester nezinye izibulala-zinambuzane.
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 ℃.
Ukuvuza ukwelashwa okuphuthumayo
Izinyathelo zokuzivikela, okokuvikela kanye nezinqubo zokulahla izimo eziphuthumayo zabaqhubi:
Kutuswa ukuthi abasebenzi bezokwelashwa kwezimo eziphuthumayo bagqoke izinto zokuphefumula komoya, izingubo ezimelene nokuqina kanye namagilavu amelana nowoyela wenjoloba.
Ungathinti noma unqamule okuchithekile.
Zonke izinto ezisetshenziswa ngesikhathi sokusebenza kufanele zimiswe phansi.
Sika umthombo wokuvuza ngangokunokwenzeka.Susa yonke imithombo yokuthungela.
Indawo yesixwayiso izoqokwa ngokuya ngendawo ethintwe ukugeleza koketshezi, isitimu noma ukusakazeka kothuli, futhi abasebenzi abangabalulekile bazokhishwa baye endaweni yokuphepha besuka ezivunguvungwini nasezindaweni ezivunguzayo.
Izinyathelo zokuvikela imvelo: ziqukethe ukuvuza ukugwema ukungcoliswa kwemvelo.Vimbela ukuvuza ekungeneni kwendle, emanzini angaphezulu nangaphansi komhlaba.
Izindlela zokugcina nezindlela zokususa zamakhemikhali avuzile nezinto zokulahla ezisetshenzisiwe:
Ukuvuza okuncane: qoqa uketshezi oluvuzayo esitsheni esivalekayo ngokusemandleni akho.Gcoba ngesihlabathi, ikhabhoni ecushiwe noma ezinye izinto ezingasebenzi bese udlulisela endaweni ephephile.Ungasheleli kumtapo wendle.
Ukuvuza okukhulu: yakha i-dike noma umbe umgodi ukuze wamukele.Vala ipayipi lokudonsa amanzi.Igwebu lisetshenziselwa ukuvala ukuhwamuka.Dlulisela emotweni yethangi noma eqoqweni elikhethekile elinepompo elingaqhumisi, ligaywe kabusha noma lithuthelwe endaweni yokuhlanza imfucuza ukuze ilahlwe.
Izinto zokuzivikela:
Ukuvikela ukuphefumula: lapho ukugxila emoyeni kudlula izinga, gqoka imaski yegesi yesihlungi (imaski enguhhafu).Lapho uhlenga noma uphuma esimweni esiphuthumayo, kufanele ugqoke izinto ezisetshenziswayo zokuphefumula umoya.
Ukuvikela isandla: gqoka amagilavu amelana nowoyela wenjoloba.
Ukuvikela iso: gqoka amehlo okuvikela ukuphepha kwamakhemikhali.
Ukuvikelwa kwesikhumba nomzimba: gqoka izingubo zokusebenza ezingena ushevu.
