Ko te hanganga karaihe o te waikawa acetic e whakaatu ana ka herea nga ngota ngota ki roto i nga dimer (e mohiotia ana ano he dimer) e nga here hauwai, a kei te noho ano nga dimer i roto i te ahua kohu i te 120 ° C. He nui te pumau o nga Dimer, a kua whakamatauhia he carboxylic. ko nga waikawa he iti te taumaha ngota penei i te waikawa formic me te waikawa acettic kei te ahua o nga dimer i roto i te ahua totoka, te wai, te hau ranei na roto i te whakatau i te taumaha ngota ma te whakaiti i te ira mīti me te wehenga hihi-X.Ka rewa te waikawa ahetiki ki te wai, ka whati tere nga here hauwai i waenga i nga dimer.Ko etahi atu waikawa carboxylic e whakaatu ana i te whakamaaramatanga.

Whakamahi Hua
Te whakamahi ahumahi
1. Ko te waikawa acetic he hua matū nui, ko tetahi o nga waikawa waro tino nui.Ka whakamahia te nuinga mo te hanga o te anhydride acetic, acetate me te cellulose acetate.Ka taea te hanga i te polyvinyl acetate ki nga kiriata me te whakapiri, a ko te mea ano hoki o te muka waihanga Vinylon.Ka whakamahia te acetate Cellulose ki te hanga rayon me te kiriata pikitia.
2. Ko te ester acetic i hangaia e nga waipiro iti he whakarewa pai, he nui te whakamahi i roto i te ahumahi peita.Na te mea ka memeha te nuinga o nga mea waro, ka whakamahia ano hei whakarewa waro (hei tauira mo te whakapouritanga o te p-xylene ki te whakaputa waikawa terephthalic).
3. Ka taea te whakamahi i te waikawa acetic i etahi otinga whakakoi me te whakakorikori, i roto i te otinga waikawa ngoikore hei parepare (pērā i te piauau, whakakikorua nickel electroless), i roto i te electrolyte whakakikorua nickel āhua-marama hei taapiri, i roto i te otinga passivation o te konutea. , Ka taea e te cadmium te whakapai ake i te kaha hononga o te kiriata passivation, me te whakamahi noa ki te whakatika i te pH o te pati waikawa ngoikore.
4. mo te hanga acetate, penei i te konupora, te konutai, te mata, te konumohe, te zinc, te cobalt me etahi atu tote whakarewa, e whakamahia nuitia ana hei whakakorikori, te tae papanga me nga taputapu hiako hiako;Lead acetate he peita te tae mata ma;Ko te Lead tetraacetate he reagent synthesis organic (hei tauira, ka taea te whakamahi i te tetraacetate mata hei kaikawe whakarorohiko kaha, whakarato i te puna o te acetoxy me te whakarite i nga pūhui mata waro, me etahi atu).
5. Ka taea hoki te whakamahi i te waikawa ahetiki hei reagent tātari, te whakahiato waro, te poaka me te whakahiato tarukino.
Te whakamahi kai
I roto i te ahumahi kai, ka whakamahia te waikawa acetic hei waikawa, hei kai reka me te kakara i te wa e hanga ana i te winika waihanga, ka whakahekehia te waikawa acetic ki te 4-5% ki te wai, me te taapiri i nga momo kai reka.He rite te reka ki te winika waipiro, he poto te wa hanga, he iti te utu.Ka rite ki te māngai kawa, ka taea te whakamahi mo te kinaki pūhui, te whakarite i te winika, te kēne, te tiēre me te tiihi, kia rite ki nga hiahia hanga o te whakamahi tika.Ka taea hoki te tito i te whakanui kakara o te waina parakihe, ko te nui o te whakamahinga he 0.1 ~ 0.3 g/kg.
