Hoʻolauna
ʻO ka dimethyl azelaic acid (ʻike pū ʻia ʻo Dioctyl adipate, DOA) he pūhui kūlohelohe maʻamau. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, hana hana a me ka ʻike palekana:
ʻAno maikaʻi:
- Ke ʻano: ʻaʻohe kala i ka wai melemele
- Hoʻoheheʻe: hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik, hiki ke hoʻoheheʻe iki i ka wai
- Hōʻike hoʻohālikelike: ma kahi. 1.443-1.449
E hoʻohana:
- Hoʻohana nui ʻia ʻo Dimethyl azelarate e like me ka plasticizer, nona ka plasticity maikaʻi a me ke kūpaʻa anu, a hiki ke hoʻonui i ka palupalu a me ke kūpaʻa anuanu o nā plastics.
- Hoʻohana pinepine ʻia i ka hana ʻana o ka polyvinyl chloride (PVC) plastics, synthetic rubber, synthetic resins, etc., e hoʻomaikaʻi i ko lākou plasticity a me ka ikaika.
- Hiki ke hoʻohana ʻia ʻo Dimethyl azelaate ma ke ʻano he lubricant, softener a me antifreeze, i waena o nā mea ʻē aʻe.
Hanana:
Hoʻomākaukau ʻia ka dimethyl azelaic acid e ka hopena esterification penei:
1. E hana i ka nononediol me ka waika adipic.
2. E hoʻohui i nā mea esterifying, e like me ka sulfuric acid, e like me nā catalysts i ka hopena esterification.
3. Hoʻokō ʻia ka hopena ma lalo o nā kūlana wela a me ke kaomi kūpono e hana ai i ka dimethyl azelaate.
4. Hoʻomaʻemaʻe hou ʻia ka huahana e ka dehydration, distillation a me nā hana ʻē aʻe.
ʻIke palekana:
- Pono e pale ʻia ka dimethyl azelaic acid ma lalo o nā kūlana hoʻohana maʻamau a pale i ka pili ʻana me ka ʻili a me nā maka.
- E hoʻohana i nā mea pale kūpono, me ka pale hanu a me nā mīkina lima pale, inā hoʻohana.
- Pono e noʻonoʻo i kahi kaiapuni maikaʻi i ka wā o ka hana e pale aku ai i ka inhalation a i ʻole ka ʻai ʻana.
- I ka wā mālama a me ka lawe ʻana, pono ia e pale i ka hoʻopili ʻana me nā oxidants, nā waikawa a me nā mea ʻē aʻe e pale aku ai i nā pōʻino weliweli.
