Monomethyl dodecanedioate(CAS#3903-40-0)

Hoʻolauna

ʻO Monomethyl dodecanedioate, i ʻike ʻia ʻo octylcyclohexylmethyl ester, he mea hoʻohuihui.

ʻAno maikaʻi:

- Ke ʻano: ʻike pinepine ʻia ka Monomethyl dodecanedioate ma ke ʻano he wai kala ʻole.

- Solubility: Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me nā ʻawaʻawa, ethers, a me nā ketones.

- Lae Ho'ā: Ma kahi o 127°C.

E hoʻohana:

- ʻO ka Monomethyl dodecanedioate kahi mea waiwai nui, i hoʻohana pinepine ʻia i ka hoʻomākaukau ʻana i nā lubricants kiʻekiʻe a me nā lubricants kiʻekiʻe.

- Hiki ke hoʻohana ʻia e like me ka plasticizer no nā plastics a me ka rubber, e hoʻonui i ko lākou maʻalahi a me ka hana.

- Hiki ke hoʻohana ʻia ka Monomethyl dodecanedioate ma ke ʻano he mea maka no ka synthesis organik, e like me ka hoʻomākaukau ʻana i nā dyes, fluorescents, melting agents a me plasticizers.

Hanana:

ʻO ka hoʻomākaukau ʻana o ka monomethyl dodecanedioate e hana maʻamau ʻia e nā pae aʻe:

1. E hoʻohui i ka ʻakika dodecanedioic a me ka methanol i ka reactor.

2. ʻO ka hopena esterification i ka mahana kūpono a me ke kaomi maʻamau e pono ai ke kū ʻana o kahi catalyst e like me ka sulfuric acid a i ʻole hydrochloric acid.

3. Ma hope o ka hopena o ka hopena, hoʻokaʻawale ʻia ka huahana a hoʻomaʻemaʻe ʻia e ka kānana a i ʻole ka distillation.

ʻIke palekana:

- Hōʻalo i ka inhalation, pili me ka ʻili a me nā maka. Pono e ʻaʻahu ʻia nā mea pale kūpono e like me nā mīkina lima, nā aniani pale, a me nā lole pale i ka wā o ka hana.

- Hōʻalo i ka hoʻopili ʻana me nā mea oxidizing ikaika i ka wā mālama a me ka lawe ʻana e pale aku i ke ahi a me ka pahū.

- I ka lawelawe ʻana a me ka hoʻolei ʻana i ka ʻōpala, e mālama i nā kānāwai kūloko a me nā lula pili, a e hoʻolei i ka ʻōpala ma ke kūpono.
