Te Hiranga Kai me te Mea Kakara Diethyl Disulfide/Ethyl Disulfide [110-81-6] FEMA 4093

Ingoa matū: Diethyl Disulfide
Ngā kupu taurite: Ethyl Disulfide; ethane-1,1-bis(thiolate); Diethyl disulphide
Taumaha ngota: C2H4S2
Āhua: Wai mārama ki te wai kōwhai
Te Pūmautanga: 1. Kaua e pirau i te pāmahana me te pēhanga noa, karohia te pā atu ki ngā waikura.
2. Kei roto i te auahi matua.

Ko te Diethyl disulfide (110-81-6) he hinu kore tae, bp 151-153 ℃, n20D 1.5060, kiato whanaunga 0.993, kāore e wairewa i te wai, ka wairewa i roto i ngā whakarewa waro. Ko te whakamahinga o te Diethyl disulfide 1, he takawaenga o te bactericide ethylallicin. 2, hei tikanga whakaputa takawaenga hanga waro, ko te tikanga whakarite ko te tuku tuatahi i te otinga konutai whanariki tangata ki roto i te tauhohenga, e ai ki te konutai whanariki: whanariki =1∶1 (ōwehenga molar) ka whāngaihia ki roto i te paura whanariki, ka whakamahanahia te topenga, ka whakaohokia, ina tae te pāmahana ki te 80 ~ 95 ℃, ka pupuri i te wera mō te 1 haora kia whiwhi ai i te otinga konutai disulfide (Na2S2). Kātahi ka papuhia te otinga disodium disulfide ki roto i te tauhohenga alkane ka tīmata te whakaoho. I te wā i whakakorengia ai te tauhohenga ki te (2 ~ 3.3)×104Pa, ka katihia te takirere korehau, ā, ka whakaurua te chloroethane. I whakahaeretia te pāmahana tauhohenga ki te 75 ~ 90℃, i whakahaeretia te pēhanga ki te (1.17 ~ 1.18)×105Pa, ā, ko te ōwehenga whāngai (ōwehenga molar) ko te sodium disulfide ∶ chloroethane =1∶2. I muri i te haere i roto i te chloroethane, ka whakamataohia te rauemi ki raro iho i te 50°C, ā, ka papuhia te hinu ki te wehewehe wai mō te wehewehenga tūmau, ā, ko te paparanga hinu o runga te hua kua oti. 2C2H5Cl+Na2S+S→C2H2 -- S -- S -- C2H5+2NaCl Ngā mōhiohio hua Ngā rauemi mata o runga Te tohatoha wai whanariki Takirere disodium Molybdenum disulfide hua o raro zinc diethyl dithiocarbamate ethyl alliin quiforn.
