Kupu Whakataki

Ko te Butyl acetate, e mohiotia ana ko te butyl acetate, he wai kore tae me te kakara kare e rewa te wai. E whai ake nei he kupu whakataki mo nga rawa, nga whakamahinga, nga tikanga whakarite me nga korero haumaru o te butyl acetate:

Kounga:

- Te ahua: Te wai marama kore tae

- Tātai rāpoi: C6H12O2

- Taumaha rāpoi: 116.16

- Kiato: 0.88 g/mL i te 25 °C (marama)

- Ira Kohua: 124-126 °C (marama)

- Ira Whakarewa: -78 °C (marama)

- Wairewa: He iti te wairewa ki te wai, he memeha i roto i te maha o nga whakarewa waro

Whakamahia:

- Nga tono Ahumahi: Ko te Butyl acetate he whakarewa pararopi nui, e whakamahia nuitia ana i roto i nga peita, i nga paninga, i nga kopa, i nga waituhi me etahi atu mara ahumahi.

- Tauhohenga matū: Ka taea hoki te whakamahi hei tïpako me te whakarewa i roto i te whakahiato waro mo te whakarite i etahi atu puhui waro.

Tikanga:

Ko te whakarite o te butyl acetate i te nuinga o te wa ka whiwhihia ma te esterification o te waikawa acetic me te butanol, e hiahia ana ki te whakamahi i te waikawa waikawa penei i te waikawa sulfuric, waikawa phosphoric ranei.

Mōhiohio Haumaru:

- A ape i te ngongo, te pa ki te kiri me te horomia, ka mau i nga karapu whakamarumaru, nga karaehe me nga parepare kanohi ina whakamahi.

- Whakamahia i roto i te waahi pai-hau me te karo i te noho roa ki nga kohinga teitei.

- Whakaorangia mai i te mura me te waikura kia mau tonu ai.
