Isingeniso
I-M-chlorobenzene iyinhlanganisela yezinto eziphilayo.
Ikhwalithi:
Iso le-M-chlorobenzene i-crystalline engenambala noma impushana ecwebezelayo enomsebenzi okhethekile wokuxegisa kanye nokubulala izinambuzane. Cishe ayincibiliki emanzini kodwa incibilika kuzincibilikisi zemvelo njenge-ethanol ne-ether. Iyazinzile ekamelweni lokushisa, kodwa ibola kalula ngokukhanya.
Sebenzisa:
I-M-chlorobenzene isetshenziswa kakhulu kwezolimo nokulima. Ivamise ukusetshenziswa njengesibulala-khula futhi ingasetshenziswa ukulawula ukhula nezitshalo ezikwazi ukubekezelela ukhula. I-M-chlorobenzene ingase isetshenziselwe ukubulala izinambuzane kanye nokulawula amabhu ezihlahleni.
Indlela:
I-M-chlorobenzene ngokuvamile ilungiswa ngokufakwa kwe-nitrobenzene nge-chlorination. Indlela eqondile yokulungiselela kungaba ukuncibilikisa i-nitrobenzene ku-dilute hydrochloric acid, bese wengeza i-ferrous chloride ukuze kwakhe i-m-chlorobenzene iso.
Ulwazi Lokuphepha:
I-M-chlorobenzene inobuthi obuthile futhi kufanele isetshenziswe ngokuhambisana ngokuqinile nezinqubo zokusebenza zokuphepha lapho usebenzisa. Ukuchayeka isikhathi eside noma ukuhogela kungadala umonakalo empilweni yomuntu, okuhlanganisa ukucasuka kwesikhumba namehlo, kanye nokulimala ohlelweni lwezinzwa olumaphakathi nohlelo lokuphefumula. Ngesikhathi sokusetshenziswa, kufanele kuqashelwe ukugqoka amagilavu okuvikela, izibuko kanye nemaski ukuze ugweme ukuthintana nesikhumba kanye nokuhogela uthuli. Lapho uphatha i-m-chlorobenzene, kufanele igcinwe kude namalangabi avulekile namazinga okushisa aphezulu ukuze kugwenywe ingozi yokusha nokuqhuma. Le nhlanganisela nayo idinga ukugcinwa ngendlela efanele futhi ilahlwe ukuze kuvinjelwe ukungcoliswa kwemvelo. Ngaphambi kokusebenzisa i-m-chlorobenzene, kufanele uqonde futhi uhambisane neziqondiso ezifanele zokusebenza kwezokuphepha kanye nemithethonqubo.
