Kupu Whakataki

Ko te waikawa Isobutyric, e mohiotia ana ko te waikawa 2-methylpropionic, he puhui waro. Ko nga korero e whai ake nei mo nga ahuatanga, nga whakamahinga, nga tikanga whakarite me nga korero haumaru o te waikawa isobutyric:

Kounga:

Te ahua: Te wai kore tae me te kakara reka.

Kiato: 0.985 g/cm³.

Wairewa: Ka whakarewahia ki te wai me te maha o nga whakarewa waro.

Whakamahia:

Wairewa: Na te pai o te wairewa, ka whakamahia te waikawa isobutyric hei whakarewa, ina koa i roto i nga peita, peita, me nga kai horoi.

Tikanga:

Ko te tikanga o te whakarite i te waikawa isobutyric ka riro mai i te waikura o te butene. Ko tenei tukanga ka whakakorikorihia e te whakakorikori, ka mahia i nga waahi teitei me nga pehanga.

Mōhiohio Haumaru:

Ko te waikawa Isobutyric he matū pirau ka whakapataritari me te kino ina pa ana ki te kiri me nga kanohi, me mau nga whakatupato tika ina whakamahia.

Ko te rongo mo te wa roa ka maroke, ka pakaru, me nga tauhohenga mate mate.

I te wa e rongoa ana me te whakahaere i te waikawa isobutyric, me noho ke atu i te mura o te ahi me te wera nui kia kore ai e puta he ahi me te pahū.

Tōmua: 5-Methyl-2-hepten-4-one(CAS#81925-81-7)

Panuku: 1,2,3,5,6,7-Hexahydro-1,1,2,3,3-pentamethyl-4H-inden-4-one(CAS#33704-61-9)
