1,2-Dichloroethane: Ikhemikhali Yetimboni Lehlukahlukene
Tindzawo Letinkhulu Tesicelo
Embonini yemakhemikhali, kusetjentiswa lokuyinhloko kwe 1,2-dichloroethane njengentfo leluhlata yekukhicita ivinyl chloride. I-Vinyl chloride yi-monomer lebalulekile lesetjentiselwa kukhicita i-polyvinyl chloride (PVC), ipulasitiki lesetjentiswa kakhulu ekwakhiweni, emaphayiphi, ekuvikeleni tintsambo, kanye nasetintfweni tekupakisha. Ngekwengeta, 1,2-dichloroethane ingaguculwa ibe yi-acetylene ngekutsi kukhishwe emanti. iAcetylene yintfo lebalulekile lesemkhatsini yekuhlanganiswa kwetilwane, isetjentiswa ekukhiciteni imikhicito leyehlukene yemakhemikhali lefana ne acetaldehyde, i-acetic acid, kanye ne chloroprene irabha.
Emkhakheni wekuncibilikisa, i1,2-dichloroethane yincibilikisi lesebenta kahle yetilwane lekhona kuncibilikisa tinhlobo letiningi tetinhlanganisela tetilwane kanye nema polymers. Ivame kusetjentiselwa kuhlanta kanye nekususa emafutsa etindzaweni tensimbi, ikakhulukati etimbonini tekucubungula te-elekthronikhi kanye netemishini. Ngetulu kwaloko, i1,2-dichloroethane isetjentiselwa kususa pende kanye nekugcobisa, kanye nekuhlanta tintfo tekushicilela embonini yekushicilela.
Etimbonini tetibulala tilwane kanye neliphunga, 1,2-dichloroethane isetjentiswa njengentfo lesemkhatsini. Ingasetjentiswa kuhlanganisa imitsi yekubulala tilwane leyehlukahlukene, njengemitsi yekubulala titjalo kanye netibulala tinambuzane, letisetjentiswa kakhulu kutekulima. Ngekwengeta, i1,2-dichloroethane ingasetjentiswa kukhicita emakha kanye nekunambitseka, kusetjentiswa kakhulu etimbonini tekudla kanye netimonyo.
Ekuhlanteni emanti, tintfo letisuselwa ku 1,2-dichloroethane, njenge polyethylene lene chlorinated, tisetjentiswa kwenta tintfo letingangeni emanti kanye nekumelana nekugcola. Letintfo tisetjentiswa kakhulu ekwelapheni kwekuvikela emanti etakhiweni kanye nemishini yetimboni, kuvikela kahle kungena kwemanti kanye nekugcola.
Noma ngabe isetjentiswa kakhulu etimbonini, i1,2-dichloroethane inebuthi, futsi kusetjentiswa kwayo kudzinga kunamatsela ngalokucinile emitsetfweni yekuphepha. Umkhicito wetimboni uvame kusebentisa tinhlelo letivaliwe kwentela kunciphisa kugucugucuka kwawo futsi ufakwe tinhlelo tekwelapha umoya letiphumelelako kanye nekukhipha umsindvo kwentela kuvikela imphilo yetisebenti kanye nekuphepha kwemvelo. Ngekukhula kwekucaphela imvelo, inchubo yekukhicita i1,2-dichloroethane nayo iyalungiswa kwentela kunciphisa umtselela wayo endzaweni.

Ngalokufishane
Ngalokufishane, i1,2-dichloroethane, njengentfo lehlukahlukene yemakhemikhali laphilako, iphetse sikhundla lesibalulekile embonini. Akugcini nje ngekuniketa emandla ekukhicita emakhemikhali lahlukahlukene labalulekile kepha kuphindze kusekele kutfutfukiswa kwemboni yesimanje. Ngekuchubeka kwetebucwepheshe, ematfuba esicelo se 1,2-dichloroethane atawuba banti kakhulu.
