Kupu Whakataki
Ko te waikawa 2,3,4-Trifluorobenzoic he pūhui waro. E whai ake nei he kupu whakataki mo tona ahuatanga, te whakamahinga, te tikanga whakarite me nga korero haumaru:
Kounga:
- Te ahua: Ko te waikawa 2,3,4-trifluorobenzoic he totoka karaihe kore tae.
- Wairewa: Ka whakarewahia i roto i nga whakarewa pararopi penei i te ethers me te waipiro, me te whakarewa paku ki te wai.
- Pumautanga: He rite tonu te pumau i te pāmahana rūma, engari ka taea te whakaheke ma te kaha o te waikura kaha, te whakaheke ranei i nga matū i te pāmahana teitei.
- Kiato: approx. 1.63 g/cm³.
Whakamahia:
- 2,3,4-Trifluorobenzoic waikawa Kei te whakamahia nuitia hei takawaenga nui i roto i te whakahiato waro.
- Ka taea hoki te whakamahi hei parenga mura i roto i te paninga, te waikano, te kirihou, me te polymers.
Tikanga:
Ko te waikawa 2,3,4-Trifluorobenzoic ka taea te whakarite ma nga huarahi waihanga e whai ake nei:
- Ka tauhohehia te waikawa benzoic ki te trifluoroacetyl chloride ki te whakaputa 2,3,4-trifluorobenzoyl chloride.
- Na, ka tauhohehia te 2,3,4-trifluorobenzoyl chloride ki te wai kia hoatu he waikawa 2,3,4-trifluorobenzoic.
Mōhiohio Haumaru:
- Ko te puehu me te kohu o te waikawa 2,3,4-trifluorobenzoic ka whakapataritari i nga kanohi, kiri me te punaha manawa.
- Mau taputapu whakamarumaru whaiaro e tika ana penei i nga kaakahu whakamarumaru, nga karapu, me nga kaarei whakamarumaru ina whakamahi, e whakahaere ana ranei.
- I te wa e pa ana ki te puhui, me horoi tonu te waahi kua pa ki te wai ma, me rapu wawe nga rongoa.
- I te wa e rongoa ana me te whakahaere, me mau nga tikanga haumaru me nga tikanga, penei i te pupuri i te taiao hau pai me te karo i te pa atu ki nga matū hotokore.
