1.Ngā āhuatanga matū:
Te wai marama kowhai marama.He kakara kino.Kare e rewa ki te wai, ka taea te konatunatua ki te waihano, te etera, me te waikawa acetic.
2. Kaupapa:
Ka whakamahia hei kaihoko whakangao mo nga whakarewa, whakakorikori, takawaenga pesticide, aukati coking, aha atu. Ka tauhohe te Dimethyl disulfide ki te cresol ki te whakaputa i te 2-methyl-4-hydroxy anisulfide, katahi ka whakamatao ki te O, O-dimethyl phosphoryl sulfide chloride i roto i te Chemicalbook alkaline reo kia whiwhi Fenthion.He ngarara ūkuikui pararopi tino pai me te iti te paitini me te tino pai o te whakahaere ki runga i nga kai raihi, nga noke ngakau soya, me nga torongū gadfly.Ka taea hoki te whakamahi hei rongoa kararehe hei whakakore i nga kutukutu kau me nga kutu taiepa kau.
3.Te tikanga whakaputa:
①Ka whiwhi i te hohenga o te Dimethyl sulfate me te Sodium sulfide.Tāpirihia te paura whanariki ki roto i te wairewa konutai sulfide i raro i te whakaohooho, whakanekehia te pāmahana ki te 80-90 ℃, tauhohe mo te 1h, ka whakahekehia te pāmahana o Chemicalbook ki te 30 ℃;Ka makahia te Dimethyl sulfate ki roto i te hohenga tauhohenga, ka haere tonu te tauhohenga mo te 2 haora, katahi ka whakamarohia, ka tu mo te paparanga.I muri i te wehewehe i te waipiro alkali para, ka whiwhi te hua kua oti ma te whakamaarama.
②Dimethyl disulfide te synthesized e te tikanga Dimethyl sulfate i roto i te ahumahi.
Na2S+S → Na2S2Na2S2+(CH3) 2SO4 → CH3SSCH3+Na2SO4
Kuhua te konutai sulfide me te wai ki roto i te ketere tauhohenga, whakamahana, ka whakahaere i te pāmahana i te 50~60 ℃ ki te tareka te konutai pukapuka matū whanariki, katahi ka tapirihia he whanariki equimolar ki roto i nga puranga, kia mahana mo te 1h, whakamatao ki te 45 ℃, timata maturuturu te Dimethyl pūkawa ngāwha, pupuri i te pāmahana tauhohenga i waenganui i 40 ~ 45 ℃, kia mahana mo te 1h i muri i te tāpiri, a ka whakaeto te hua Dimethyl disulfide.I tua atu, ka taea hoki te whakahiato a Dimethyl disulfide ma te tikanga methyl mercaptan.
③Ka puta mai i te tauhohenga o te iodomethyl magnesium me te Disulfur dichloride.He mea hanga na te tauhohenga o te konutai disulfide me te konutai methylsulfate.Ka whakaritea te Methyl Sodium thiosulfate ma te tauhohe i te Bromomethane ki te Sodium thiosulfate, katahi ka whakamahana.
4.Storage me te kawe waka:
Te hau me te whakamaroke iti-mahana o te whare putunga;Rokiroki motuhake mai i te hāora me te waikawa
5.Kaipatu ahi
Te paura maroke, te onepu maroke, te waro hauhauora, te pahuka, 1211 te kai whakaweto
I tenei wa, kei te tuku tonu a Jinan ZhongAn Industry Co., Ltd i te DMDS ki nga maakete nui.I te marama o Hepetema o tenei tau, ka whakawhānuihia e Jinan ZhongAn Industry Co., Ltd ta tatou raina whakaputa ki te whakatutuki i nga hiahia o nga kaihoko.Ka mihi matou ki nga kaihoko mai i nga wa katoa o te ao ki te korero mai ki a maatau.Kua whiwhi ano to taatau kamupene i te tiwhikete ISO9001.Tena koa kia okioki mo te kounga o te hua.
