methyl pent-4-ynoate（CAS# 21565-82-2)

Hoʻolauna

ʻO ka methyl pent-4-ynoate he mea hoʻohuihui mea ola me ke kumu kemika C7H10O2. ʻO kēia ka wehewehe ʻana o kona ʻano, hoʻohana, hana a me ka ʻike palekana:

ʻAno:

-Nani: methyl pent-4-ynoate he wai kala ʻole;

-Solubility: Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka ethanol a me ka ether, paʻakikī ke hoʻoheheʻe i ka wai;

-Ke kumu hoʻolapalapa: ʻo kona wahi e hoʻolapalapa ai ma kahi o 142-144 ℃;

-Density: ʻO kona mānoanoa ma kahi o 0.95-0.97g/cm³.

E hoʻohana:

-Hoʻohui kemika: hoʻohana pinepine ʻia ka methyl pent-4-ynoate ma ke ʻano he mea waena i ka synthesis organik a hiki ke hoʻohana ʻia e synthesize i nā pūhui organik ʻē aʻe;

-ʻOihana meaʻala a me nā meaʻala: Heʻalaʻala kona a hiki ke hoʻohanaʻia i ka hoʻomākaukauʻana i nā meaʻala a me nā meaʻala.

Hanana:

Hiki ke hoʻomākaukau ʻia ka methyl pent-4-ynoate e nā ʻano hana penei:

-Etherification pane: pent-1-yne a me methanol ua esterified i mua o ka catalyst e hana i ka methyl pent-4-ynoate.

ʻIke palekana:

Pono ka methyl pent-4-ynoate e hoʻolohe i ka ʻike palekana i ka wā e hoʻohana ai a mālama ai:

-ʻawaʻawa: ʻO ka methyl pent-4-ynoate he mea hoʻohuihui kino, hiki ke loaʻa kekahi mea ʻona i ke kino kanaka. I ka hoʻohana ʻana, e pale i ka pili ʻana me ka ʻili a me nā maka, a pale i ka hoʻohu ʻana i kona mahu;

-ahi: ʻO ka methyl pent-4-ynoate he wai wela, pono e pale i ka pili me ka lapalapa ākea a me ka wela kiʻekiʻe, pono e mālama ʻia ka mālama ʻana mai ke ahi.

E ʻoluʻolu, pono e hahai ʻia nā hana hoʻokolohua kūpono a me nā kaʻina hana palekana i ka wā e hoʻohana ai a mālama i nā kemika, a pono e nīnau ʻia nā ʻoihana kūpono no ka ʻike kikoʻī palekana.
