Kupu Whakataki
waikawa pent-4-ynoic, e mohiotia ana ko te waikawa pent-4-ynoic, tauira matū C5H6O2. E whai ake nei he kupu whakataki mo te ahua, te whakamahinga, te hanga me nga korero haumaru o te waikawa pent-4-ynoic:
Taiao:
- Ko te waikawa pent-4-ynoic he wai karekau he haunga.
-Ko 102.1g/mol te papatipu ngota ngota whanaunga.
Whakamahia:
- Ko te waikawa pent-4-ynoic he takawaenga nui i roto i te whakahiato matū ka whakamahia hei whakarite i etahi atu puhui.
-Ka taea te whakamahi mo te tauhohenga waro, te tauhohenga condensation me te tauhohenga esterification i roto i te tauhohenga whakahiato waro.
- Ka taea hoki te whakamahi waikawa pent-4-ynoic ki te whakarite i nga raau taero, kakara me nga tae.
Tikanga Whakaritenga:
-Ko te whakarite o te waikawa pent-4-ynoic ka taea e te 1-chloropentyne me te waikawa waikawa. Tuatahi, ka tauhohehia te 1-chloropentyne ki te wai hei hoatu i te aldehyde, i te ketone ranei, katahi ka huri te aldehyde me te ketone ki te waikawa pent-4-ynoic ma te tauhohenga waiora.
Mōhiohio Haumaru:
- Ko te waikawa pent-4-ynoic he matū whakapataritari ka pa ki te kiri me nga kanohi.
-Kia mau karapu tiaki, mohiti, me nga kakahu taiwhanga ina whakamahi waikawa pent-4-ynoic.
-Mena ka pa ki te kiri, ki nga kanohi ranei, horoi tonu ki te nui o te wai me te rapu rongoa.
-Kaore i te pa atu ki nga waikura, nga waikawa kaha me nga turanga kaha i te wa e rokiroki ana me te whakamahi hei karo i nga tauhohenga kino.
Kia mohio koe i mua i te whakamahi i tetahi matū, me ata panui koe i te pepa raraunga haumaru (MSDS) o te matū me te whai i nga tikanga whakahaere tika me nga tikanga whakahaere haumaru.
