1.Ngā āhuatanga matū:
He wai mārama, he kōwhai mārama. He haunga kino. Kāore e wairewa i roto i te wai, ā, ka taea te whakaranu ki te etanoru, te etera, me te waikawa acetic.
2. Kaupapa:
Whakamahia hei kaiārai whakakore mō ngā whakarewa, ngā whakakorikori, ngā takawaenga pesticide, ngā aukati coking, me ētahi atu. Ka tauhohe te dimethyl disulfide ki te cresol hei whakaputa i te 2-methyl-4-hydroxy anisulfide, kātahi ka whakapūpūhia ki te O, O-dimethyl phosphoryl sulfide chloride i roto i te reo kawakore Chemicalbook hei whiwhi i te Fenthion. He patu pepeke phosphorus waro whai hua, he iti te paitini, he pai rawa ngā pānga whakahaere ki ngā kutu raihi, ngā kutu ngākau pīni soya, me ngā torongū namu. Ka taea hoki te whakamahi hei rongoā kararehe hei whakakore i ngā kutu namu kau me ngā kutu pakitara kau.
3. Tikanga whakaputa:
①Ka whiwhi mā te tauhohenga o te Dimethyl sulfate me te Sodium sulfide. Tāpirihia te paura whanariki ki roto i te otinga Sodium sulfide me te whakaoho, whakanuia te pāmahana ki te 80-90 ℃, tauhohe mō te 1 hāora, ka whakaiti i te pāmahana o Chemicalbook ki te 30 ℃; ka maturuturu te Dimethyl sulfate ki roto i te ipu tauhohenga, ka haere tonu te tauhohenga mō te 2 hāora, kātahi ka whakapūtā, ka waiho kia takoto mō te paparanga. I muri i te wehenga o te wai para kawakore, ka whiwhihia te hua kua oti mā te whakapūtā.
②Ka hangaia te dimethyl disulfide mā te tikanga Dimethyl sulfate i roto i te ahumahi.
Na2S+S → Na2S2Na2S2+(CH3) 2SO4 → CH3SSCH3+Na2SO4
Tāpirihia te konutai whanariki totoka me te wai ki roto i te ipu tauhohenga, whakamahanahia, whakahaeretia te pāmahana ki te 50~60 ℃ hei whakarewa i te konutai whanariki, kātahi ka tāpirihia te whanariki equimolar i roto i ngā puranga, pupuri kia mahana mō te 1 hāora, whakamatao ki te 45 ℃, tīmata ki te maturuturu i te Dimethyl sulfate, pupuri i te pāmahana tauhohenga i waenga i te 40~45 ℃, pupuri kia mahana mō te 1 hāora i muri i te tāpiri, kātahi ka mimiti i te hua Dimethyl disulfide. Hei tāpiri, ka taea hoki te hanga Dimethyl disulfide mā te tikanga methyl mercaptan.
③Ka puta mai i te tauhohenga o te iodomethyl magnesium me te Disulfur dichloride. Ka hangaia mā te tauhohenga o te konutai disulfide me te konutai methylsulfate. Ka hangaia te Methyl Sodium thiosulfate mā te tauhohenga o te Bromomethane me te Sodium thiosulfate, kātahi ka whakamahana.
4. Ngā āhuatanga rokiroki me te kawe:
Te whakapūhau me te whakamaroke i te whare putunga i te pāmahana iti; Rokiroki motuhake mai i ngā waikura me ngā waikawa
5.Ākena tinei ahi
Paura maroke, onepu maroke, hauhā waro, pahuka, 1211 kai tinei
