Waikawa acetic, he wai kore tae, he tino kaha te kakara.Ko te rewa o te waikawa acetic he 16.6 ℃, te ira koropupū he 117.9 ℃, te kiato whanaunga he 1.0492 (20/4 ℃), me te taupū whakaata he 1.3716.Ka taea e te waikawa ahetiki parakore te hanga i te totoka rite ki te hukapapa i raro iho i te 16.6 °C, no reira ka kiia ko te waikawa acettic glacial.Ko te waikawa acetic he rauemi matū matū nui, e whakamahia ana ki te whakarite i te vinyl acetate monomer (VAM), cellulose acetate, acetic anhydride, terephthalic acid, chloroacetic acid, polyvinyl alcohol, acetate me te whakarewa acetate.
Ka whakamahia nuitia te waikawa acetic i roto i te whakahiato waro taketake, rongoa, pesticides, ta me te tae, kakano, kai, peita, whakapiri me te maha atu o nga umanga.Ko te waikawa ahetiki he rawa matū nui.Ko nga hangarau whakangao ahumahi o te waikawa acetic ko te nuinga ko: te tikanga warowaiwai methanol, te waikura acetaldehyde, te whakangao tika o te ethylene me te waiora hinu marama.I roto ia ratou, ko te methanol carbonylation te hangarau e whakamahia nuitia ana, neke atu i te 60% o te katoa o te kaha whakaputa o te ao, kei te tipu tonu tenei ahuatanga.
Ko te kaha o te hanga waikawa acetic o te ao kua piki ake, a ka tipu ano te hiahia o te ao ki te reeti tau toharite mo te 5% i roto i nga tau e whai ake nei, e 94% o te kaha o te hanga waikawa acetic hou o te ao ka puta i roto Ahia, me te rohe o Ahia ano hoki a muri ake nei.Ko te arahi i te tipu tere o te tono maakete o te ao i roto i nga tau e rima.
