M'nkhani zaposachedwa, mankhwala a dimethyl disulfide (DMDS) akhala akupanga mafunde m'mafakitale osiyanasiyana chifukwa cha ntchito zake zosiyanasiyana komanso chitukuko chomwe chikuchitika.

Dimethyl disulfide, madzi opanda mtundu kapena achikasu owala omwe ali ndi fungo lomveka bwino komanso lopweteka, apezeka pamalo ake m'magawo osiyanasiyana. Mumakampani opanga mafuta, imagwira ntchito yofunika kwambiri ngati chothandizira kupanga ma catalyst omwe amagwiritsidwa ntchito popanga mafuta opangidwa ndi hydrodesulfurization.

Komanso, DMDS ndi chinthu chofunikira kwambiri popanga mankhwala ophera tizilombo. Imagwira ntchito ngati gawo lapakati pakupanga mankhwala ophera tizilombo monga fenthion. Mwachitsanzo, imagwira ntchito ndi cresol ndikupanga 2 - methyl - 4 - hydroxyanisole sulfide, yomwe imakonzedwanso kuti ipange fenthion, mankhwala ophera tizilombo omwe ali ndi poizoni wotsika kwambiri wa organophosphorus. Mankhwala ophera tizilombowa amagwiritsidwa ntchito kwambiri poletsa tizilombo monga mpunga, soya borers, ndi gadfly mphutsi, ndipo ingagwiritsidwenso ntchito ngati mankhwala a ziweto kuti athetse mphutsi ndi nkhupakupa.

Pakupanga mankhwala, DMDS imagwiritsidwa ntchito popanga mankhwala ena ofunikira okhala ndi sulfure. Ingagwiritsidwe ntchito popanga zinthu za methylsulfonyl chloride ndi methylsulfonic acid, zomwe zimagwiritsidwa ntchito m'njira zosiyanasiyana zamankhwala.

Msika ndi kupanga kwa DMDS zikusinthanso. Mu 2023, Msonkhano woyamba wa National Dimethyl Disulfide Industry Exchange unachitikira ku Yiwu County. Anakambirana za mwayi ndi zovuta zomwe makampani a DMDS akukumana nazo, ndipo adayambitsa njira yake yopangira methyl mercaptan sulfidation mdziko muno - yoyamba - yopanga DMDS. Njirayi sikuti imangotsimikizira zinthu zabwino kwambiri komanso imawonjezera kugwiritsa ntchito mpweya wotayira ndi mpweya wam'mbuyo, zomwe zimachepetsa kwambiri kuwonongeka kwa chilengedwe poyerekeza ndi njira zachikhalidwe.

Pamene mafakitale akupitilizabe kukula ndikupeza mayankho ogwira mtima komanso okhazikika, dimethyl disulfide ikuyembekezeka kukhala ndi gawo lofunika kwambiri mtsogolo, zomwe zikuyendetsa zatsopano ndikukula m'magawo a mafuta, mankhwala, ndi ulimi.
