Ukuhlanganiswa okukhohlisayo.
I-2-aroyl chloride iyi-liquid esolisayo ebilayo ngo-173 ° C, ecasulayo emehlweni kuneBenzoyl Chloride.
I-2-boroyl chloride iyi-intermediatical ewusizo yezemithi futhi isetshenziswa ku-synthetasone furoate,
I-Foldrug ye-antiinflarmatory esetshenziswe ekwelapheni ukuphazamiseka kwesikhumba, i-hay fever kanye nesifo somoya.
I-Synthesis of Furtheic Acid Derivatives: Isetshenziswa kakhulu njenge-ejenti yokuhlobisa ukuhlanganisa okuhlukahlukene okuvela e-acid acid, okungasetshenziswa emikhakheni kanye nama-agrochemicals.
Ukuhlelwa kwe-organic okuphakathi nendawo: 2-Froyl Cloride ingumphakathi obalulekile ekuhlanganiseni kwezinye izivumelwano ze-organic (kufaka phakathi amakhompiyutha we-heterocyclic kanye namakhompiyutha ahlukahlukene asebenza).
Ukulungiselela ama-esters kanye nezindlela: ama-ester kanye nezingadi kungalungiswa ngokuphendula ngotshwala nama-amine ngokulandelana, okungasetshenziswa ukukhiqiza imikhiqizo ehlukahlukene yamakhemikhali.
Izemithi: Ngenxa yokuvuselelwa kwayo, ingasetshenziselwa ukuthuthukisa amakhompiyutha emithi, ikakhulukazi lezo ezidinga ukwethulwa kweqembu le-furanoyl.
Ucwaningo lwamakhemikhali: Kusetshenziswa kaningi kuzilungiselelo zocwaningo ukuthuthukisa izindlela ezintsha zokwenziwa futhi uhlole izindlela zokuphendula ezibandakanya ama-acyl clorides.
Gcina endaweni yokugcina epholile, eyomile futhi enomoya owanele.
Gwema kude nomlilo nemithombo yokushisa. Gwema ukukhanya kwelanga okuqondile.
Iphakethe livaliwe.
Kufanele igcinwe ngokwahlukana kusuka kumakhemikhali anamakhemikhali adliwayo, nesitoreji esixubile akufanele kugwenywe.
Indawo yokugcina kufanele ifakwe ngezinto ezifanele ukuqukatha ukuvuza.
Isitsha: Gcina i-2-furoyl chloride esitsheni esivalwe esisenziwe ngezinto ezihambisanayo, njengengilazi noma ipulasitiki ethile engamelana namakhemikhali awonakalisayo. Qiniseka ukuthi isitsha sibhalwe ngokucacile.
Ukushisa: gcina iziqukathi endaweni epholile, eyomile kude nokukhanya kwelanga okuqondile nokushisa. Uhla lokushisa lungu-15-25 ° C (59-77 ° F).
Unert Gas: Uma kungenzeka, gcina ngaphansi kwegesi e-inert enjenge-nitrogen noma i-argon ukunciphisa ukuvezwa komswakama nomoya, okungadala i-hydrolysis nokukhululwa kwe-hydrochloric acid.
Gwema Ukuxhumana namanzi: Kusukela 2-Froyl Chloride iphendula ngamanzi, sicela uqinisekise ukuthi indawo yokugcina akuyona emanzi futhi isitsha sihlala somile.
Izindlela zokuphepha: Gcina endaweni enomoya owanele kude nezinto ezingahambelani ezifana nezisekelo eziqinile, ama-alcohols kanye nama-amone. Sebenzisa imishini yokuvikela yomuntu siqu efanelekile (i-PPE) lapho uphatha i-compound.
Ukulahlwa: Lapho izinto eziyingozi zingasadingeki, sicela uzichichise ngokuya ngemithetho yendawo.

1, inani: 1-1000 kg, kungakapheli izinsuku ezi-3 zokusebenza ngemuva kokuthola izinkokhelo
2, inani: ngaphezulu kwe-1000 kg, kungakapheli amasonto ama-2 ngemuva kokuthola izinkokhelo.
Yebo, 2-boroyl chloride kuyingozi kubantu. Kuhlukaniswa njengento elonakalisayo futhi kungahle kungacasuli isikhumba, amehlo, kanye nepheshana lokuphefumula. Nazi ezinye zezingozi ezithile ezihambisana ne-2-boroyl chloride:
1. Isikhumba nokucasulwa kwamehlo: Ukuxhumana ngqo ne-2-boroyl chloride kungadala ukucasuka okukhulu noma ukushiswa. Gqoka njalo izingubo ezifanele zokuvikela, amagilavu kanye nama-goggles lapho uphatha le compact.
2 Kunconywa ukugcina umoya omncane wokwanele noma usebenzise i-fume hood lapho kuvezwa kwale makhemikhali.
I-3. Ukusebenza kabusha
4. Ubuthi: Yize idatha ethile yobuthi ingalinganiselwe, ukuvezwa ku-acyl clorides kubangela ubungozi bezempilo nokusingathwa ngokucophelela kunconywa.
Ukunciphisa ubungozi, Njalo ukulandela imihlahlandlela yokuphepha, sebenzisa imishini efanelekile yokuzivikela (i-PPE), futhi usebenze endaweni enomoya owawungena kahle lapho uphatha i-chloride engu-2-froyl. Uma kwenzeka kuvezwa, funa ukwelashwa ngokushesha.
