| I-NHDuhlobo olusha lwe-solvent olusebenza kahle kakhulu lokususa i-sulfurizing kanye ne-de-carbonated oluhlanzekile kakhulu, i-chemistry enhle kakhulu kanye nokuqina kokushisa ezindaweni ezine-asidi ephezulu, i-alkality kanye nokushisa. Lufanelekela ukuhlanzwa kwegesi eyenziwe nge-anthraco. Lungasusa i-hydrogen evulcanized ngempumelelo kugesi ye-asidi exubile yegesi yemvelo, igesi yensimu kawoyela, igesi yamalahle emafektri noma emadolobheni kanye negesi kaphethiloli encibilikisiwe. Ikakhulukazi, lungasusa i-sulfuri ephilayo ngempumelelo. |
Okwedlule: Ama-polyether agcwele amabhlogo I-Diethylene glycol methyl ethyl ether (DEME)/ I-Dipropylene glycol ether (DPDM) Olandelayo: Uchungechunge lwe-polyethylene glycol monomethyl ether (MPEG)
