Kulungiswa kanye nekuhlukaniswa
Ngemuva kwekutsi sekwentiwe i-ester, kulungiswa kuyadzingeka kwentela kwehlukanisa i-maleic anhydride kusuka kumikhicito lehambisanako. Lenchubo idzinga imishini lezinzile kanye nemisebenti lesemgangatfweni. Le maleic anhydride lehlukanisiwe ibese iyachubeka nekuphelelwa ngemanti, kukhishwa kwembala, kanye nekususwa kwekungcola kwentela kukhulisa kuhlanteka kwayo kanye nelizinga layo.
Kuhlantwa kwegesi lelahliwe
Kukhicita iMaleic anhydride kukhicita igesi lenkhulu lelahliwe (lecuketse tintfo letiphilako letifana ne benzene kanye ne carbon dioxide). Kulapha kumele kuhlangabetane nemazinga emvelo: tintfo letifanele kanye netinyatselo (sib., tintfo letimuncako, kushisa kwe catalytic, noma imibhoshongo yekumunca) kumele kusetjentiswe kususa tintfo letinebuthi, kuvikela imvelo kanye nekuphepha kwetisebenti.
Ngalokufishane, tidzingo tebuchwepheshe tekukhicita i-maleic anhydride tifaka ekhatsi kukhetsa tintfo letiluhlata, kukhetsa i-catalyst, kulawula simo sekuphendvula, kulawula i-esterification, kulungisa/kwehlukanisa, kanye nekuhlantwa kwegesi lelahliwe. Kulawula ngekwesayensi kanye nekunengcondvo kwaletincenye kwenta kutsi kukhicitwe kahle ngesikhatsi kucinisekiswa lizinga lemkhicito kanye nekuphepha kwemvelo.

Emashumi Lamabili Eminyaka Ehola Kutfunyelwa Kwema-Maleic Anhydride! Umkhicito we-Shandong Puli Chemical lolinganisekako, kulawula lizinga lokucinile, kanye netisombululo tekugcina kuya ekugcineni kugcina emakhasimende emhlabeni wonkhe embili. Ufuna kukhiya umkhumbi wakho lolandzelako? Thepha lesixhumanisi kute uxhumane!
