Anhydride ahetiki: āhuatanga, te faaineineraa, me te whakamahi

Anhydrides o ngā waikawa - he hua o te maroketanga o te rāpoi ngota. E āhuatanga ēnei e Radicals poinanahatanga biosoedineny. A, no te whakaingoa anhydrides waikawa tino whakamahia nuitia nomenclature hītori (hei tauira, anhydride, waikawameha ahetiki, anhydride maleic, me ētahi atu). I roto i te tua o ngā waikawa dehydrating āpiha (nuinga hikahika waikura) puta ratou maroketanga, hua i roto i te hanganga o anhydrides waikawa.

anhydride ahetiki: takanga o

Ka taea te horoi i te pūhui taitara whiwhi maha ngā huarahi. Hoki tona kōtuitanga tino whakamahia nuitia ūkuikui waikura, i te mea he kaihoko dehydrating rawa kaha. He hoki atu tikanga mo te kōtuitui o anhydride. Hei tauira, e taea te whiwhi anhydride ahetiki i raro i te mahi o te Phosphate rite te anhydride waikawa tāpia. Ko te tukanga meangiti e tapiritia dropwise SN3SOS1 kotahi korakora ia matūriki dewatered ka maroke tino waikawa-konutai tāpia. I hana te ranunga hua tika, ka nekehia atu te anhydride ahetiki synthesized i roto i te pati one, me te ka pure i te Māturu. Ka rite ki te hua o te mahi hua kaha hongi waikawa tāpia wai.

anhydride ahetiki, me matū iti-rāpoi - wai ki te kakara koi, ngā rewakore i roto i te wai, ngāwari wairewa i roto i maha matū organic. Me kï reira e nga anhydrides o teitei waikawa (rawa whāiti) - totoka koreami. Ratou pāmahana kohua tino teitei ake i te waikawa e ōrite ana.

anhydride ahetiki: Āhuatanga Chemical

Kei te whakamahia nuitia tenei pūhui mō ngā mema maha o ngā akomanga rerekē o ngā matū waro e ngā tikanga o te kōtuitanga organic. I roto i te tauhohenga o te anhydrides ki te wai ki te homai e rua ngā rāpoi ngota o te waikawa hāngai.

Amonoliz anhydrides arata'i ki te hanganga o amides me te haukinia tai o te waikawa e ōrite ana. Ko te tauhohe whakamahia mō te whiwhi alkoliza ki anhydrides hākawa.

whakamahia anhydride Acetal te rite te dehydrating me kaihoko acetylating i roto i te atsetiltselyulozy production tukanga, vinyl tāpia, ngā rongoā, dimethylacetamide, colorants, matū kakara, me ētahi atu Kei te irritating hāparo-tahi tāpia ki te wahi romahā, kanohi, a ka meinga weranga kiri.

Cellulose tāpia whiwhi tika ki te mahi i runga i te anhydride cellulose tāpia i te aroaro o te whakakōkī (ngāwhā waikawa). rite acetylation oti ki Pālesi, me te cellulose diacetates. triacetate Di- me te cellulose whakamahia i roto i te hanga o te hiraka tāpia. Kua rewa ratou hoki tenei whakaaro i roto i te ranunga o te hauwaiwaro me waihā ewaro (85:15) ranei i roto i te hauwaiwaro parakore. whiwhi otinga Kaore e extruded nei i roto i whiriwhiringa motuhake. maroke takai angiangi o te otinga ki runga, ka tahuri ki ngangana, e kua whakamahia mo te hanga o rerekē momo o rinena o muka waihanga.

Kei te whakamahia te tono ahumahi, me te tahi atu anhydrides. anhydride Maleic - taonga, tioata, pai wairewa i roto i te wai, me te i roto i te hauwaiwaro, rewa ana i 52,85 ° C. Tikanga, rite tenei rauemi i te waikawa maleic. Whakamahia i roto i te hanga o ngā patukīrea, pareaku me resins alkyd. whakaputaina anhydride Phthalic te tika ki te hāora o te naphthalene. Kei te whakamahia te whakamutunga mo te kōtuitui o ngā kaiwhakatairanga tipu, insecticides, me te tahi mau rongoā. anhydride Phthalic - tioata totoka ki te ira whakakoero o 128 ° C. Ka mea whakamahia anhydride te ki whiwhi Waipūhuitohukonu (tohu me te medicament). Kei te whakamahia i tēnei anhydride mo te repellents hanga (dimethyl phthalate).
