Kupu Whakataki

Ko te waikawa dimethyl azelaic (e mohiotia ana ko Dioctyl adipate, DOA) he puhui waro noa. E whai ake nei he kupu whakataki mo tona ahuatanga, te whakamahinga, nga tikanga whakangao me nga korero haumaru:

Kounga:

- Te ahua: Kore tae ki te wai kowhai

- Te wairewa: he whakarewa i roto i nga whakarewa pararopi, he rire noa ki te wai

- Taupū Refactive: āhua. 1.443-1.449

Whakamahia:

- Ko te Dimethyl azelarate te nuinga o te whakamahi hei kirihou, he pai te kirihou me te aukati makariri, a ka taea te whakanui ake i te ngawari me te aukati makariri o nga kirihou.

- He maha nga wa e whakamahia ana i roto i te hanga o te polyvinyl chloride (PVC) kirihou, te rapa waihanga, te rei waihanga, me etahi atu, hei whakapai ake i to raatau kirihou me te kaha.

- Ka taea hoki te whakamahi i te Dimethyl azelaate hei whakahinuhinu, hei whakangawari me te antifreeze, me era atu mea.

Tikanga:

Ko te waikawa Dimethyl azelaic te nuinga o te wa ka mahia ma te tauhohenga esterification e whai ake nei:

1. Tauhohehia te nonediol ki te waikawa adipic.

2. Tāpirihia he mea whakakorikori, penei i te waikawa sulfuric, hei whakakorikori i roto i te tauhohenga esterification.

3. Ka mahia te tauhohenga i raro i te pāmahana tika me nga tikanga pehanga hei whakaputa i te dimethyl azelaate.

4. Ka purea ano te hua ma te whakamaroke, te whakamaarama me etahi atu waahanga.

Mōhiohio Haumaru:

- Me whakamarumaru te waikawa dimethyl azelaic i raro i nga tikanga whakamahi noa me te karo i te pa ki te kiri me nga kanohi.

- Mau taputapu whakamarumaru tika, tae atu ki te whakamarumaru manawa me nga karapu whakamarumaru, mena ka whakamahia.

- Me aro atu ki tetahi taiao hau pai i te wa e mahi ana kia kore ai e pangia te hau, i te horonga pokanoa ranei.

- I te wa o te rokiroki me te kawe waka, me aukati te pa atu ki nga waikura, waikawa me etahi atu matū hei karo i nga aitua kino.
