Kupu Whakataki
Ko te waikawa dimethylmalonic (e mohiotia ana ko te waikawa succinic) he puhui waro. E whai ake nei he kupu whakataki mo nga rawa, nga whakamahinga, nga tikanga whakarite me nga korero haumaru o te waikawa dimethylmalonic:
Kounga:
- Te ahua: Ko te waikawa Dimethylmalonic he kiriataata kore tae, he paura ma ranei.
- Wairewa: Ka whakarewahia i roto i nga whakarewa noa penei i te wai, te waihano me te etera.
Whakamahia:
- Hei rauemi mata ahumahi: Ka taea te whakamahi ki te whakahiato i te kapia polyester, te whakarewa, te paninga me te whakapiri.
Tikanga:
- Ko te tikanga noa mo te whakarite i te waikawa dimethylmalonic ka whiwhi ma te hydroformylation o te taapiri ethylene. Ko te mahi motuhake ko te whakamau i te ethylene me te waikawa formic ki te hanga waikawa glycolic, katahi ka haere tonu te tauhohenga esterification i waenga i te waikawa glycolic me te waikawa formic kia whiwhi ai i te hua whakamutunga waikawa dimethylmalonic.
Mōhiohio Haumaru:
- Ko te waikawa dimethylmalonic he kore paitini, engari me whai whakaaro tonu ki te whai i nga tikanga whakahaere haumaru i roto i te taiwhanga me te waahi whakaputa.
- Aukati i te haunga o te puehu, te pa ranei ki te kiri me nga kanohi ina whakamahi ana, ka mau i nga taputapu whakamarumaru e tika ana (hei tauira, nga karapu me nga karu).
- Mena ka pa atu, ka horoi tonu i te waahi kua pa ki te wai maha ka rapu awhina hauora mena e tika ana.
