Ukulungiswa nokuhlukaniswa
Ngemva kokwenza i-esterification, ukulungiswa kuyatlhogeka ukuhlukanisa i-maleic anhydride emikhiqizweni. Ikambiso le idinga iinsetjenziswa ezizinzileko nemisebenzi ejwayelekileko. I-maleic anhydride ehlukanisiweko ibe seyenza ukuphelelwa mamanzi, ukususwa kombala, nokususwa kokungcola ukuthuthukisa ubumsulwa nekhwalithi yayo.
Ukuhlanzwa kwegesi elahliweko
Ukukhiqizwa kwe-Maleic anhydride kukhiqiza ivolumu ekulu yegesi elahliweko (equkethe izinto eziphilako ezifana ne-benzene ne-carbon dioxide). Ukwelatjhwa kufanele kuhlangabezane namazinga wezebhoduluko: imitjhini neenlinganiso ezifaneleko (isib., izinto ezimunyako, ukutjhiswa kwe-catalytic, nofana imibhobho yokudosa) kufanele zisetjenziselwe ukususa izinto ezinobuthi, ukuvikela ibhoduluko nokuphepha kwabasebenzi.
Ngokurhunyeziweko, iimfuneko zethekhnikhi zokukhiqiza i-maleic anhydride zifaka hlangana ukukhethwa kwezinto ezisetjenziswako, ukukhethwa kwe-catalyst, ukulawulwa kobujamo bokuphendula, ukulawulwa kwe-esterification, ukulungiswa/ukuhlukaniswa, kanye nokuhlanzwa kwegesi elahliweko. Ukulawulwa kwesayensi nokunengqondo kwalezi zici kwenza bona kube nokukhiqiza okuphumelelako ngesikhathi kuqinisekiswa ikhwalithi yomkhiqizo nokuphepha kwebhoduluko.

Iminyaka ematjhumi amabili yokudosa phambili ukuthunyelwa kwe-Maleic Anhydride! Umkhiqizo we-Shandong Puli Chemical, ukulawulwa kwekhwalithi okuqinileko, kanye nezisombululo ezipheleleko zigcina amaklayenti ephasini loke phambili. Ufuna ukukhiya umthwalo wakho olandelako?
