trans-2-Hexen-1-Al Diethyl Acetal(CAS#54306-00-2) hoolauna
waiwai kino
ʻIke ʻia: ʻIke pinepine ia me he wai ʻaʻa ʻole i ka ʻulaʻula melemele māmā, ʻoi aku ka maʻalahi o ka hana ʻana i nā kaʻina hana kemika e like me ka lawe ʻana i nā mea a me ka hui ʻana i nā hopena.
ʻala: He ʻala hua ʻokoʻa kona, he hou a kūlohelohe. Ua huki nui ʻia kēia hiʻohiʻona i ke kahua o ka ʻala ʻala, a hiki ke hoʻohana ʻia ma ke ʻano he kumu kī no ka hui ʻana i ka ʻono hua.
Solubility: Hiki iā ia ke hoʻoheheʻe maikaʻi i ka hapa nui o nā mea hoʻoheheʻe organik, e like me ka ethanol, ether, acetone, a me nā mea ʻē aʻe, e maʻalahi ai ka hui ʻana a me ka hoʻopili ʻana me nā reactants ʻē aʻe i loko o nā ʻōnaehana hoʻohālikelike organik; ʻO ka hoʻoheheʻe ʻia i loko o ka wai he palena liʻiliʻi ia, e like me ke kānāwai hoʻoheheʻe ʻana o nā pūhui organik me ka nui o ke kalapona.
ʻO ka paila paila: Loaʻa iā ia kahi pae paila kikoʻī, he kumu nui ia no ka hoʻokaʻawale ʻana a me nā hana hoʻomaʻemaʻe e like me ka distillation a me ka hoʻoponopono. Hiki ke ʻano liʻiliʻi ke ʻano o ka paila o nā laʻana me nā maʻemaʻe like ʻole, a hiki ke loiloi mua ʻia ka maikaʻi a me ka maʻemaʻe o ka huahana ma ke ana pololei ʻana i ka helu paila.
4、 Waiwai kemika
ʻO ka hopena hydrolysis acetal: Ma lalo o nā kūlana ʻawaʻawa, ʻo ke ʻano diethylacetal i loko o ka mole e maʻalahi i ka hydrolysis, e hana hou i nā pūʻulu aldehyde a me ka ethanol. Hoʻohana pinepine ʻia kēia ʻano i ka synthesis organik no ka hoʻololi ʻana o ka pūʻulu hana a i ʻole ka pale pūʻulu aldehyde, a hoʻokuʻu ʻia i ka manawa kūpono e komo ai i nā hopena hope.
Pane hoʻohui paʻa pālua: Hiki i nā paʻa kalapona kalapona pālua ke hana ma ke ʻano he wahi hana a hoʻohui ʻia me ka hydrogen, halogens, etc.
ʻO ka hoʻoheheʻe ʻana: Ma lalo o ka hana a nā mea hoʻokahe kūpono, hiki i nā molekole ke komo i ka oxidation, ka haki ʻana i ka paʻa paʻa pālua, a i ʻole ka hoʻoheheʻe ʻia ʻana o nā pūʻulu aldehyde e hoʻohua i nā huahana oxidation kūpono, e hāʻawi ana i ke ala no ka synthesis o nā pūhui paʻakikī ʻē aʻe.
5 、 Keʻano hana hoʻohui
ʻO ke ala synthetic maʻamau e hoʻomaka me ka trans-2-hexenal a hana ʻia me ka ethanol anhydrous i ke alo o nā mea hoʻoheheʻe ʻakika e like me ke kinoea hydrogen chloride maloʻo, p-toluenesulfonic acid, a pēlā aku. ka laulā o ka haʻahaʻa haʻahaʻa i ka lumi wela, e pale aku i nā ʻaoʻao ʻaoʻao mai ka hiki ʻana mai; I ka manawa like, pono e hōʻoia i kahi kaiapuni anhydrous, no ka mea hiki i ka wai ke hoʻohuli i ka hopena aldol a hoʻopilikia i ka hua. Ma hope o ka pau ʻana o ka hopena, hoʻokaʻawale ʻia ka catalyst me ka hopena alkaline, a laila hoʻokaʻawale ʻia e ka distillation, hoʻoponopono a me nā ʻano hana ʻē aʻe e loaʻa ai nā huahana i hoʻomaʻemaʻe ʻia.
