Kupu Whakataki

Kei roto i ngā kāponāte porowhita ngā kāponāte mema-rima, ngā kāponāte mema-ono, ngā kāponāte mema-whitu me ngā kāponāte porowhita-nui e whitu, neke atu rānei, ā, ko te kāponāte propylene me te kāponāte ethylene ngā mea e whakamahia whānuitia ana. He rauemi mata pai rawa atu te kāponāte ethylene hei whakarewa me te whakakoi i ngā matū, e whakamahia whānuitia ana i roto i ngā kirihou, te tā me te tae, te hanga pūmua, te wehenga hau me te matū hiko.

Ngā āhuatanga matū: Kore tae, kore kakara, wai mura. Ka taea te whakaranu ki te ether, acetone, benzene, chloroform, ethyl acetate, me ētahi atu, ka wairewa ki te wai me te waro tetrachloride.

Ngā Whakamahinga: Hei whakarewa hinuhinu, hei whakarewa miro, hei tango olefin me te kakara, hei mimiti hauhā waro, hei whakamarara mō ngā tae me ngā tae wairewa-wai, me ētahi atu.

Ngā Tikanga Whakaputa 1. Tikanga Phosgene Ka tauhohe te rauemi mata o te propylene glycol ki te phosgene hei whakaputa i te hydroxyisopropyl chloroformate, kātahi ka tauhohe ki te konutai hauwai hei whakaputa i te propylene carbonate, kātahi ka whiwhi i te hua kua oti mā te whakakore korehau. 2. Tikanga whakawhiti Ester. 3. Tikanga Chloropropanol. 4. Tikanga hanga propylene oxide me te waro hauhā Ka tauhohe te waro hauhā me te propylene oxide i te 150-160℃ me te 5MPa hei whakaputa i te propylene carbonate. Ka whiwhi i te hua kua oti mā te whakakore korehau. Kua whakawhanakehia ngā tikanga o runga ake nei, engari he nui ngā utu whakaputa o ngā tikanga tuatahi e toru, ā, he iti te kounga o te hua, nō reira ka whakakapia mārire e te tikanga tuawhā. 5. Tikanga hanga propylene oxidation me te waro hauhā. He tikanga hanga tēnei i whakawhanakehia i roto i te taiwhanga i ngā tau tata nei.
