Kupu Whakataki
Ko te waikawa 2,5-Dihydroxybenzoic 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 2,5-dihydroxybenzoic he paura tioata ma.
- Wairewa: Ka taea te memeha i roto i te wai me nga whakarewa pararopi penei i te waiwaro me te chloroform.
- pH: He ngoikore te waikawa i roto i nga wairewa wai.
Whakamahia:
- Te whakahiato matū: Ka taea te whakamahi waikawa 2,5-dihydroxybenzoic hei rauemi mata mo te whakahiato waro, ka uru atu ki nga momo tauhohenga matū hei whakarite i etahi atu puhui.
Tikanga:
- Ko te tikanga whakareri e whakamahia nuitia ana ko te whakahiatotanga o te waikawa 2,5-dihydroxybenzoic na roto i te waikawa waiariki o te waikawa phthalic.
Mōhiohio Haumaru:
- Ko te waikawa 2,5-Dihydroxybenzoic he iti te kino ki te tangata me te taiao i raro i nga tikanga whakahaere noa.
- Ka whakapataritari, ka pirau ki nga kanohi me te kiri, me karo i te wa e whakahaere ana. Mena ka pa mai, ka horoi tonu me te nui o te wai.
- I te wa e rokiroki ana, me tupato kia kore e pa atu ki nga waikura kaha, te teitei o te mahana, me nga puna mura ki te whakaiti i nga tupono haumaru.
