DPG yana daya daga cikin mafi mahimmancin masu tallata vulcanization na roba, wanda aka fi amfani dashi a cikin roba na halitta da na roba. Yana da kyakkyawan juriya na tsufa a cikin rubber vulcanized da kuma ACTS a matsayin mai kunnawa na thiazole, thiuram da sulfonamide. amfani da wakili na taimako da sauransu, galibi USES wajen kera taya da samfurin roba da sauransu akan tafin roba.

Babban samar da matakai na mai gabatarwa DPG sun hada da cyanide chloride, karfe oxide desulfurization da hadawan abu da iskar shaka desulfurization.A tsakanin su, catalytic oxygen hadawan abu da iskar shaka shi ne mafi dace tsari ga kore sunadarai.

A halin yanzu, da hanyoyin masana'antu na roba vulcanization mai talla DPG suna amfani da oxygen a matsayin oxidant, a karkashin catalysis na jan karfe acetate mai kara kuzari, da albarkatun kasa diphenyl thiourea (CA) ammonia ne oxidized don samar da mai gabatarwa DPG.Specifically, (1) shirye-shiryen diphenyl thiourea ta hanyar farko hadawa da carbon sa'an nan susulfiline tare da ruwa da sulfiline da ruwa tare da sulfiline. diphenyl thiourea an haɗe shi da ruwa, an ƙara ammonia, oxygen ya wuce ta, kuma diphenyl guanidine an samu ta hanyar catalytic oxidation reaction.(3) samfurin sai a narkar da shi a cikin acid don tace magudanar. Sa'an nan kuma a yi amfani da ruwa alkali don hazo da tace samfurin. Sa'an nan kuma an wanke gishiri mai yawa a cikin samfurin tare da ruwa mai yawa. Wannan hanya ita ce ta gargajiya. Domin tabbatar da canjin canjin CA a cikin tsarin samarwa, ana buƙatar yawan ruwan ammonia gabaɗaya. A cikin tsarin samarwa, iskar ammonia da iskar oxygen suna da sauƙi don samar da cakuda mai fashewa, wanda ke haifar da haɗari mai girma. A lokaci guda, don hanzarta saurin amsawa, tsarin samarwa yana buƙatar samar da wani nau'i na matsa lamba, ƙarfin juriya na kayan aiki kuma ana buƙatar, tsawon lokaci{11} tsarin aiki na bukatun kayan aiki yana da girma, zuba jari na masana'antu yana da girma.

Bugu da kari, a halin yanzu, da kira tsari na promotor DPG, yafi rungumi dabi'ar irin kettle reactor ga tsari aiki, da tsari yana da matukar tasiri da ma'aikata aiki, don haka da samfurin ingancin ne yiwuwa ga rashin zaman lafiya. Reactor na matsin lamba yana da girma, kuma yana da sauƙi a sami matsala a cikin dogon lokaci{2}}.

Microchannel reactor yana da babban yanki na musamman, haɗawa da sauri, babban canjin canjin zafi na canja wurin zafi, yanayin yanayi na uniform kuma ya jawo hankalin masu bincike da yawa a fagen haɓakar sinadarai, babban canjin wurin sa, saurin canja wurin zafi don yin yawan amsawa na iya fahimtar ingantaccen iko, sannan kuma zuwa ka'idar nan take amsawa, don haɓaka ingancin samfura da ingantaccen aiki.

Hanyar ci gaba da samar da vulcanization accelerator DPG yana buƙatar ƙarin bincike.
