Waiwaihā faaineineraa: Methods me Raw Materials

E whakamahia waiwaihā i roto i na maha ahumahi me mahi. O ratou hua ngā waerau waihanga, plasticizers, rubbers, teretere, me te maha atu ngā momo o ngā hua. kawea faaineineraa o te waiwaihā i roto i te whakamahi i ngā tikanga matüora me matū. He tokomaha o ratou he hua papatipu o te matūngahinu kōtuitanga. Matū kōtuitanga o waiwaro ko te tikanga production āhua ngāwari. Ko hoki reira tetahi o nga tikanga tino nui ko te hanga o ngā waiwaihā ki olefins hydration. Ko te kupu whiwhi isopropyl, apooraa na me tert-butyl me Ethyl waiwaihā. hāngai faaineineraa o te methyl waipiro (methanol) kei runga i te Māturu maroke o te rakau.

tukanga Basic e hua waiwaihā:

• Kawakore pärönaki paparetanga kōnakonako: production o nonireka, benzyl waipiro me ētahi atu.
• epoxides hydration me ngā waiwaro rua: ethylene glycol, te waihā me te rite.
• Hydroformylation: waihā owaro, waihā mewaro, me ētahi atu
• tikanga hāora: te hanga o waiwaihā fatty.
• Methods Whakaora: teitei waiwaihā fatty, Xylitol me etahi atu.
• tikanga matüora: te hanga o te nonireka me waihā ewaro.

Ko tētahi o te hua papatipu-hua te nuinga he waipiro Ethyl (waihā). I tona pūtake, i whakawhanakehia ai i te tikanga mō te whakaputa rapa waihanga. whiwhi te waihā te i ngā hua rakau paparetanga, ethylene sulfite waipiro me te tikanga enzymatic o kai rauemi mata.

He utu me te wa e kai ana tukanga takanga o waiwaihā (te waihā me te methanol) i te kai rauemi mata, me te rakau. Ko Ethyl waipiro nui atu pai, me te māmā ki te whakaputa i i te feedstock pūwaro inexpensive, hei tauira, ki te ethylene hydration. Ki te whiwhi tetahi ton o te waihā i tikanga enzymatic, he mea e tika ana ki te tukatuka wha taranata o te witi, e waru taranata o otaota ranei. No te whakarite, i whiwhi ai tetahi ton o te waihā te i te taranata 2.5 o distillates hinu hau ethylene ranei. utu Reipa i roto i te tangata-haora i roto i te hanga o te waihā i ngā rauemi raw: witi - 160, i te rīwai - 280, o te ethylene - 10. Te faaineineraa o te waiwaihā matūngahinu feedstock he iti utu, me te wā e kai ana.

Hoki hua tino nui matū he mewaro. production Modern kawea o methanol te i na roto i te kōtuitanga organic i runga i te waro haukura (II) he hau kōtuitanga ranei i roto i te tauine ahumahi. kaupapa hangarau, i reira e rerekē. Ka taea te wehea ratou ki te rōpū e toru e whai ake.

- Synthesis o kaiwhakakökï konutea-chromium i tenge tiketike. He tawhitotia ka whakakapi i te tikanga kōtuitanga rerekē i te pēhanga iti tenei tukanga.

- Synthesis o whakakōkī parahi-konutea-konumohe i pēhanga iti. Mā te whakamahi i te tikanga o ariā o te pēhanga iti taea tino whakaiti i te utu o te hanga pūngao. Ki tenei tikanga o te hanga titau te nui rawa o te purenga o nga poke rauemi raw pēhia e pa i te whakakōkī.

- he methanol kōtuitanga e toru-wāhanga i roto i te pūnaha kawea e te roto i roto i te whakatārewatanga o te wai e mangere me te whakakōkī wehea minita. Ko te tikanga ki te whakapiki ake i tukua, i whakaiti utu pūngao tenei. E pai ake Methods o te whakarite waiwaihā. pūnaha-wāhanga e toru ko te hangarau production whakamua.
