Hoʻolauna

ʻO ka Ethyl ethynyl carbinol (Ethyl ethynyl carbinol) he mea hoʻohuihui me ke ʻano kemika C6H10O. Loaʻa ia ma ka hoʻohui ʻana i kahi hui hydroxyl (hui OH) i kahi pentyne. Penei kona mau waiwai kino.

 

He wai kala ʻole ʻo Ethyl ethynyl carbinol me kahi ʻala ʻala. Hiki ke hoʻoheheʻe ʻia i ka wai a me ka nui o nā mea hoʻoheheʻe organik e like me nā ʻawaʻawa, eter a me nā esters. He haʻahaʻa haʻahaʻa kona, ʻoi aku ka māmā ma mua o ka wai, a ʻoi aku ka nui o ka paila.

 

Loaʻa i ka Ethyl ethynyl carbinol kekahi mau hoʻohana i ka synthesis organik. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻomaka a waena i ka synthesis organik, a hoʻohana pinepine ʻia i ka hoʻomākaukau ʻana i nā pūhui carbonyl. Hiki iā ia ke komo i ka esterification alkyd, ka hoʻohui olefin, ka hopena carbonylation hydrocarbon saturated. Eia kekahi, hiki ke hoʻohana ʻia ka 1-pentyn-3-ol i ka synthesis o nā meaʻala a me nā lāʻau lapaʻau.

 

Hiki ke hoʻokō ʻia ke ʻano o ka hoʻomākaukau ʻana i ka Ethyl ethynyl carbinol e kēia mau ʻanuʻu: ʻo ka mua, hoʻololi ʻia ka pentyne a me ka sodium hydroxide (NaOH) i loko o ka ethanol e hana i ka paʻakai sodium 1-pentyn-3-ol; a laila, hoʻololi ʻia ka paʻakai sodium 1-pentyn-3-ol i ka paʻakai Ethyl ethynyl carbinol ma ka hopena acidification.

 

I ka hoʻohana ʻana a me ka lawelawe ʻana i ka Ethyl ethynyl carbinol, pono ʻoe e hoʻolohe i ka ʻike palekana e pili ana: He mea hoʻonāukiuki a hiki ke hoʻoulu a hōʻeha i ka ʻili a me nā maka, no laila pono ʻoe e hoʻokomo i nā mea pale pilikino kūpono, e like me nā mīkina lima a me nā maka. Eia kekahi, he mea puhi ia a pono e pale ʻia mai ka hoʻopili ʻana me nā lapalapa ākea a i ʻole nā ​​kumu wela kiʻekiʻe, a mālama pono ʻia. Pono e hoʻokō ʻia kēlā me kēia lawelawe a mālama ʻana paha e pili ana i ka pūhui e like me nā kaʻina hana palekana.
