Folasaga
Dimethyl azelaic acid (lea e taʻua o Dioctyl adipate, DOA) o se faʻalapotopotoga masani masani. O lo'o ta'ua i lalo se folasaga i lona natura, fa'aoga, auala gaosi ma fa'amatalaga saogalemu:
Tulaga lelei:
- Fa'aaliga: E leai se lanu i le samasama vai
- Solubility: solu i solu fa'aletino, soluness teisi i le vai
- Fa'asinomaga fa'atusa: tusa. 1.443-1.449
Fa'aaogā:
- O le Dimethyl azelarate e masani ona faʻaaogaina e avea o se plasticizer, lea e lelei le palasitika ma le malulu, ma e mafai ona faʻateleina le vaivai ma le malulu o le palasitika.
- E masani ona faʻaaogaina i le gaosiga o polyvinyl chloride (PVC) palasitika, paʻu faʻapipiʻi, resini faʻapipiʻi, ma isi, e faʻaleleia ai lo latou palasitika ma le malosi.
- Dimethyl azelaate e mafai foʻi ona faʻaaogaina e fai ma lubricant, faʻamalulu ma antifreeze, faʻatasi ai ma isi mea.
Metotia:
O le dimethyl azelaic acid e masani ona saunia e ala i le esterification reaction e pei ona taua i lalo:
1. Tali le nonediol ma le adipic acid.
2. Fa'aopoopo mea esterifying agents, e pei o le sulfuric acid, e fai ma fa'amalosi i le esterification tali.
3. O le tali e faia i lalo o le vevela talafeagai ma tulaga mamafa e gaosia ai le dimethyl azelaate.
4. O le oloa e faʻamamāina atili e ala i le faʻamama, faʻamaʻi ma isi laasaga.
Fa'amatalaga Saogalemu:
- Dimethyl azelaic acid e tatau ona puipuia i lalo ole faʻaoga masani ma aloese mai le faʻafesoʻotaʻi ma le paʻu ma mata.
- Fa'aofu mea faigaluega puipui talafeagai, e aofia ai le puipuiga o le manava ma totigilima puipui, pe a fa'aaoga.
- E tatau ona gauai atu i se siosiomaga faʻalelei lelei i le taimi o le taotoga e aloese ai mai le manava poʻo le faʻalavelave faʻafuaseʻi.
- I le taimi o le teuina ma le felauaiga, e tatau ona puipuia le faʻafesoʻotaʻi ma oxidants, acids ma isi mea e aloese ai mai faʻalavelave mataʻutia.
