trans-2,3-Dimethylacrylic acid CAS 80-59-1

maikaʻi
He wai kala ʻole ʻo Trans-2,3-dimethacrylic acid. He ʻakika a hiki ke hana me nā kumu e hana i nā paʻakai pili. Hiki iā ia ke hana ikaika me ka oxygen ma ka lumi wela a hiki ke hoʻopau koke. Hiki iā ia ke hana me kekahi mau metala e hana i nā paʻakai metala pili. ʻO Trans-2,3-dimethacrylic acid ka maikaʻi o ka solubility a hiki ke hoʻoheheʻe ʻia i ka wai a me nā mea hoʻoheheʻe organik. I ka ʻoihana, hoʻohana pinepine ʻia ia ma ke ʻano he waena i ka synthesis o nā mea hoʻohuihui organik, a hiki ke hoʻohana ʻia i ka hoʻomākaukau ʻana i kekahi mau polymers, plastics, a me nā uhi.

Hoʻohana a me nā ʻano hana synthesis
ʻO ka waikawa Trans-2,3-dimethacrylic, i kapa ʻia ʻo methylisobutenic acid, he ʻakika carboxylic unsaturated i loaʻa nā hui methyl ʻelua. Loaʻa iā ia kahi ākea o nā noi.

Hoʻohana ʻia ʻo Trans-2,3-dimethacrylic acid ma ke ʻano he monomer i ka synthesis o nā polymers. Hiki ke copolymerized me nā monomers ʻē aʻe ma o ka hopena polymerization radical manuahi, e like me ka copolymerization me ka waikawa acrylic a me ka methyl acrylate e loaʻa ai ka copolymer methylisopropyl methyl acrylate. He mau waiwai maikaʻi kēia mau polymers i nā pena, nā uhi, nā adhesives, a me nā mea ʻē aʻe, a hoʻohana ʻia e hoʻonui i ka hopena o ka hopena o nā huahana, hoʻemi i ka viscosity, etc.

ʻO ka lua, hiki ke hoʻohana ʻia ka waikawa trans-2,3-dimethacrylic ma ke ʻano he koʻikoʻi koʻikoʻi i ka synthesis organik synthetic. Hāʻawi kāna mau pūʻulu methyl ʻelua i ka pae hana no ka pane ʻana, a hiki ke hoʻomākaukau ʻia nā ʻano mea ola e nā ʻano hoʻololi hoʻololi hou aʻe. No ka laʻana, ma ka hana ʻana me nā amine a i ʻole nā ​​​​ʻawaʻawa, hiki ke hoʻohui ʻia nā pūhui hana biologically, e like me nā mea hoʻoponopono ulu ulu.

Hoʻomākaukau pinepine ʻia ke ʻano hana synthesis o trans-2,3-dimethacrylic acid e ka hopena o ka isobutylene me ka carbon monoic acid hydrate. Hoʻopili ʻia ka Isobutylene me ka hao peracid positive no ka loaʻa ʻana o ka ʻakika methylisobutenic substrate, a laila hana ʻia me ka nui o ka cuprous chloride e hana ai i nā paʻakai kūloko, a laila hana ʻia me ka waiʻona e hydrolyze e hana i ka waikawa acrylic pili.

ʻIke palekana
ʻO ka waikawa Trans-2,3-dimethacrylic he mea hoʻohuihui maʻamau, a ʻo kāna ʻike palekana penei:

1. ʻAiʻona: trans-2,3-dimethacrylic acid kekahi mau mea ʻawaʻawa a hiki ke hōʻeha i ke kino o ke kanaka. I ka hoʻohana ʻana a i ʻole ka lawelawe ʻana i kēia pūhui, pono e mālama pono ʻia e pale i ka hoʻopili pololei ʻana me ka ʻili, nā maka, a me ka ʻōpū hanu.

2. ʻO ka pōʻino o ke ahi: ʻO Trans-2,3-dimethacrylic acid kahi mea hiki ke hoʻopau i nā mahu puhi i nā wela kiʻekiʻe. I ka lawelawe ʻana a mālama ʻana paha i kēia pūhui, e pale i ka ʻā a me nā wela kiʻekiʻe, a mālama i ka ea maikaʻi.

3. Pono e hoʻopaʻa ʻia nā pono: trans-2,3-dimethacrylic acid e mālama ʻia i loko o kahi pahu airtight, ma kahi o nā kumu ahi a me nā oxidants. Pono e mālama ʻia ma kahi kaʻawale mai nā combustibles, oxidants, a me nā ʻakika ikaika e pale aku i nā hopena ulia.

4. Pane ulia pōpilikia: Inā he kahe a ulia paha, pono e hana koke ʻia nā hana ulia pōpilikia, e like me ke komo ʻana i nā lako pale pilikino kūpono, ka hoʻokuʻu ʻana i nā kānaka me ka wikiwiki, a me ka pale ʻana i nā mea mai ke komo ʻana i nā punawai a i ʻole nā ​​kumu wai ma lalo o ka honua.

5. Ka pale ʻana i ka ʻike: I ka lawelawe ʻana i ka trans-2,3-dimethacrylic acid, pono e hoʻohana ʻia nā mea pale pilikino e like me nā mīkina lima pale, nā maka aniani, a me nā lole pale e hōʻoia i ka palekana o ka ʻili, nā maka, a me ka ʻōpū hanu.

6. Holoi ʻōpala: Pono e hoʻolei pono ʻia ka ʻōpala trans-2,3-dimethacrylic acid e like me nā kānāwai kūloko. E hōʻalo i ka hoʻolei ʻana i ka ʻōpala i loko o ke kaiapuni kūlohelohe a hāʻawi iā ia i kahi hale mālama ʻōpala kūikawā no ka hoʻolei ʻana.
