Kupu Whakataki

3,4-Difluorobenzoic acid. E whai ake nei he kupu whakataki mo tona ahuatanga, te whakamahinga, te tikanga hanga me nga korero haumaru:

Kounga:

- Ko te waikawa 3,4-Difluorobenzoic he totoka kiriatai ma me te kakara reka.

- He totoka i te pāmahana rūma, ka taea te whakarewa i roto i nga whakarewa pararopi penei i te waipiro, te etera, me etahi atu, he iti te whakarewatanga ki te wai.

- Ko te waikawa 3,4-Difluorobenzoic he waikawa ka tauhohe ki te kawakore ki te hanga i te tote e rite ana.

Whakamahia:

- Ko te waikawa 3,4-difluorobenzoic e whakamahia whānuitia ana hei rauemi takawaenga nui me te rauemi mata i roto i te whakahiato waro.

Tikanga:

- He maha nga tikanga whakarite mo te waikawa 3,4-difluorobenzoic, ko tetahi o enei ka whakamahia ma te whakamahi i te waikawa fluorinated fluorinated.

- Ko te tikanga whakarite motuhake ko te kowhiringa o te kaihoko fluorinating me te whakahaere i nga tikanga tauhohenga, ko nga kaihoko fluorinating noa he hydrogen fluoride, sulfur polyfluoride, etc.

Mōhiohio Haumaru:

- Ko te waikawa 3,4-Difluorobenzoic he matū me whai i runga i nga tikanga haumaru e tika ana me nga taputapu tiaki matū tika.

- Ka pa te kino ki runga i nga kanohi, kiri, me te rewharewha, me horoi wawe i muri i te pa atu.

- I te wa e rongoa ana, me karohia te pa atu ki nga waikura kaha me nga waikawa kaha hei aukati i nga tauhohenga kino.

- Ko te waikawa 3,4-Difluorobenzoic me rongoa i roto i te waahi makariri, maroke, he pai te hau, kei tawhiti atu i nga puna ahi me te wera.
