I-Benzyl Chloride
Ukuhlolisisa komkhiqizo
I-Benzyl Chloride (eyaziwa nangokuthi yi-Benzyl Chloride, α-Chlorotoluene) yikhemikhali eqakathekileko ephakathi enefomula yamakhemikhali i-C₇H₇Cl kanye nobudisi be-molar obungu-126.58 g/mol. Njengombana ibonwa njengesisekelo sokwakhiwa kwamakhemikhali amahle, isetjenziswa khulu kizo zoke iinbulalantwala, imithi, amakha, amadayi, kanye namabubulo we-polymer. I-Benzyl Chloride yethu ilandela amazinga wekhwalithi yamazwe ngamazwe, inokwakheka okuzinzileko, ukusebenza okuthembekileko, nokulawulwa okuqinileko kokungcola – okwenza bona ibe yinto ekhethwako yokukhiqiza amakhemikhali wezinga eliphezulu.
Ngethekhnoloji ethuthukisiweko yokufaka i-chlorine eragela phambili kanye nethekhnoloji yokulungiswa enelungelo lobunikazi, siqinisekisa ikhwalithi yomkhiqizo engatjhugulukiko ehlangabezana neendingo ezihlukahlukeneko zokukhiqiza amabubulo. Umkhiqizo lo ubonakala njengoketshezi olungenambala ukuya kobuphuzi kancani olunephunga elibukhali, elihlanganiswa ne-ethanol, i-chloroform, i-ether, nezinye iinsombululo eziphilako, ngesikhathi zingancibiliki emanzini (ukuncibilika: 460 mg/L) begodu zikwazi ukutjhwaba ngomhwamuko wamanzi.

.Iinsetjenziswa ezihlukahlukeneko zebubulo
Ukusebenza kwe-Benzyl Chloride kuvela ekuphenduleni kwayo okuhle khulu, okusebenza njengesisekelo sokwakha amakhompawundi amanengi anenani eliphezulu:
Ibubulo lemithi yokubulala iinlwanyana
Ukuhlanganiswa okunqophileko kwama-organophosphorus fungicides afana ne-Kitazin P kanye ne-Iprobenfos, ezisetjenziswa khulu ekulawuleni ukuqhuma kwerayisi.
Iinsetjenziswa eziphakathi eziqakathekileko zokwenza iinbulalanambuzane (isib., i-phoxim) kanye neenbulalantwala, ezisekela umkhiqizo wezokulima ophumelelako.
Ibubulo lemithi
Iinsetjenziswa eziqakathekileko zokwenza ama-antibiotics (isib., i-benzylpenicillin), ama-antihistamines (isib., i-Diphenhydramine Hydrochloride), kanye nama-antiseptics (isib., i-Bromogeramine).
Isandulela se-phenylacetic acid nezinye izinto eziphakathi kwemithi, ezenza bona kukhiqizwe imithi ehlukahlukeneko yokwelapha.
Ibubulo Lephunga Nedayi
Ukwenziwa kwe-benzyl alcohol, i-benzyl acetate, namanye amakhompawundi wephunga asetjenziswa kumakha, izimonyo, namakhemikhali wangamalanga.
Okuphakathi kwama-auxiliaries wedayi kanye ne-m-phenoxybenzaldehyde, okufaka isandla ekwakhiweni kwedayi okuqinileko, okuzinzileko kweengubo nama-coating.
Iinthako zepholima neplastiki
Ukukhiqizwa kwe-butyl benzyl phthalate (BBP), ipulasitiki esebenza kuhle khulu ekhuphula ukuguquguquka nokuqina kwama-polymer.
Iinsetjenziswa ezihlaza zokwenza ama-resin wokwenziwa kanye nama-retardants womlilo, ukwenza ngcono ukujamelana nelangabi kanye nezakhiwo zemikhiqizo yeplastiki.
Ezinye iinsetjenziswa
Ukukhiqizwa kwe-phenylacetonitrile, i-benzoyl chloride, kanye ne-aniline ukwenzela ukulungiswa kwamakhemikhali.
Isetjenziswa eensetjenzisweni zokuqeda iindwangu, iinsetjenziswa zokuhlanza, kanye namakhemikhali wokufakwa nge-elekthronikhi, okutjengisa ukutjhuguluka okubanzi kwezebubulo.
Ukuqinisekiswa kwekhwalithi nekghono lokuphakela
Ithekhnoloji yokukhiqiza ethuthukileko: Yamukela iindlela ezisezingeni eliphezulu zokufaka i-chlorine nokulungisa ukuqinisekisa ikhwalithi yomkhiqizo efanako kanye namazinga aphasi wokungcola.
Ukulawulwa kwekhwalithi okuqinileko: Ibhetjhi ngayinye yenza ukuhlolwa okuqinileko (indlela ye-GC/FID) ukuqinisekisa ukuhlanzeka, ukuminyana, nokuqukethwe kokungahlanzeki, ngeSitifiketi sokuHlaziya (i-COA) esinikelwa kiyo yoke imithwalo.
Ukuphakelwa okukhulu: Kusekelwa sikhungo sokukhiqiza esisezingeni lephasi esinamandla wamathani ama-60,000 qobe mnyaka, esikwazi ukuhlangabezana neendingo zokuphakelwa okukhulu nezesikhathi eside.
5.Iindlela zokupakisha: Itholakala ngamabhodlela wengilazi ayi-100 ml, 1 L, 2.5 L, kanye nama-50 kg we-PE/imiphongolo yensimbi, ahambisana namazinga wokuthunyelwa nokugcina weentjhabatjhaba.
Imihlahlandlela yokuPhepha nokuPhatha
Ilwazi lengozi (ukuthobela i-GHS)
Iintatimende zobungozi: H302 (Ilimaza nayigwinywa), H315 (Ibangela ukuvuvuka kwesikhumba), H317 (Ingabangela ukusabela kwesikhumba okungekho emthethweni), H318 (Ibangela ukulimala okukhulu kwamehlo), H331 (Inobuthi nangabe iphefumula), H335 (Ingabanga ukulimala kokuphefumula), H350 (Ingabangela ukulimala kwezitho zomzimba ukuvezwa isikhathi eside).
Amabinzana wobungozi: R22, R23, R37/38, R41, R45, R48/22.
Iinjamiso zokuTjheja
Yembatha amadlhavu wokuzivikela, izambatho ezijamelana namakhemikhali, ukuvikela amehlo, kanye nama-mask wobuso lokha nawuphathako.
Balekela ukuthintana ngqo nesikhumba, amehlo, kanye nendlela yokuphefumula; hlambulula kuhle ngamanzi imizuzu ema-15+ nangabe uthintana.
Beka endaweni epholileko, eyomileko, enomoya omuhle (amazinga womtjhiso ≤30°C, umswakama ≤70%) kude nemithombo yokuvutha, ama-oksidiza, kanye namapuyere wensimbi.
Qinisekisa ukungena komoya okufaneleko ngesikhathi sokusebenzisa; sebenzisa ngaphakathi kwe-fume hood emisebenzini emincani.
Lahla iimfesi namanzi angcolileko ngokuya kwemithetho yezebhoduluko yendawo ukunciphisa umthelela wemvelo.
Imitjho yokuphepha
S45: Funa isiyeleliso sezokwelapha msinyana nakungenzeka ingozi nofana ukungakhululeki (tjengisa ilebula yomkhiqizo nangabe kungenzeka).
S53: Balekela ukuvezwa – thola imiyalo ekhethekileko ngaphambi kokusebenzisa.
