Nzira yekugadzira
1. P-chlorobenzoyl chloride yakagadzirirwa nekuita kwep-chlorobenzoyl chloride neanisole, inoteverwa nehydrolysis uye demethylation.
2. Kuita kwep-chlorobenzoyl chloride ine phenol: nyungudutsa 9.4g (0.1mol) yephenol mu4ml ye10% sodium hydroxide solution, wedzera 14ml (0.110mol) yep-chlorobenzoyl chloride inodonha pa40 ~ 45 ℃ 30min, uye ita patembiricha imwe chete ye1H.Kutonhorera kusvika kukamuri tembiricha, sefa uye kuoma kuwana 22.3g ye phenyl p-Chlorobenzoate.Goho iri 96%, uye nzvimbo yakanyunguduka i99 ~ 101 ℃.
Leakage emergency treatment
Matanho ekudzivirira, midziyo yekudzivirira uye nzira dzekukurumidzira dzekurasa kune vanoshanda:
Zvinokurudzirwa kuti vashandi vekurapa kwekukurumidzira vapfeke midziyo yekufema yemhepo, zvipfeko zveanti-static uye magirovhosi anodzivirira mafuta erabha.
Usabate kana kuyambuka marara.
Zvose zvinoshandiswa panguva yekushanda zvinofanira kuiswa pasi.
Cheka panobva kuvuza zvakanyanya sezvinobvira.Bvisa zvese zvinobatidza moto.
Nzvimbo yambiro ichasarudzwa zvichienderana nenzvimbo yakakanganiswa nekuyerera kwemvura, chiutsi kana kupararira kweguruva, uye vashandi vasina basa vachaendeswa kunzvimbo yakachengeteka kubva pakuyambuka mhepo nemhepo.
Matanho ekudzivirira kwezvakatipoteredza: ane kuvuza kudzivirira kusvibiswa kwezvakatipoteredza.Dzivirirai kubuda kwemvura kunopinda mumasuweji, mvura yemudenga nemvura yepasi.
Kuchengetedza uye nzira dzekubvisa dzemakemikari akadonhedzwa uye zvinhu zvekurasa zvinoshandiswa:
Kudonhedza kudiki: unganidza iyo inobuda mvura mumudziyo unovharika sezvinobvira.Sveta nejecha, activated kabhoni kana zvimwe zvinhu zvine inert uye woendesa kunzvimbo yakachengeteka.Usaputire mugedhi.
Kudonha kukuru: kuvaka dike kana kuchera gomba rekugamuchira.Vhara pombi yemvura.Furo rinoshandiswa kuvhara evaporation.Kuendesa kumota yetangi kana yakakosha muunganidzi ane pombi inoputika-isina kuputika, kudzokorodza kana kutakura kuenda kunzvimbo yekurasira tsvina kuti inoraswa.
Zvidziviriro zvemunhu:
Kudzivirirwa kwekufema: kana iyo fungidziro mumhepo ichipfuura mwero, pfeka sefa gasi mask (hafu mask).Paunenge uchinunura kana kubuda mune imwe nguva, unofanirwa kupfeka mudziyo wekufema mweya.
Kudzivirirwa kwemaoko: pfeka magurovhosi anodzivirira mafuta erabha.
Dziviriro yeziso: pfeka makemikari ekuchengetedza ekudzivirira maziso.
Ganda uye kuchengetedzwa kwemuviri: pfeka anti chepfu yekupinda yebasa zvipfeko.
