3-phenylprop-2-ynenitrile（CAS# 935-02-4)

Hoʻolauna

ʻO ka 3-phenylprop-2-ynenitril he mea hoʻohuihui olaola me ke ʻano kemika C9H7N. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.

ʻAno:

1. Nānā: 3-phenylprop-2-ynenitrile he wai kala ʻole i ka wai melemele māmā.

2. Ka helu hehee: ma kahi o -5°C.

3. Ke kumu hoʻolapalapa: ma kahi o 220 ° C.

4. mānoanoa: e pili ana i 1.01 g / knm.

5. Solubility: 3-phenylprop-2-ynenitrile hiki ke hoʻoheheʻe i ka hapa nui o nā mea hoʻoheheʻe organik, e like me nā ethers, nā waiʻona a me nā ketones.

E hoʻohana:

1. ma ke 'ano he mea waena i loko o ka organic synthesis.

2. ʻepekema waiwai: Hiki ke hoʻohana ʻia no ka synthesis polymer a me ka hoʻololi hana e hoʻololi i nā waiwai o nā polymers.

Hanana:

Hoʻomākaukau ʻia ka 3-phenylprop-2-ynenitril ma ka hana ʻana i kahi pūhui phenyl nitro me ka sodium cyanide. Loaʻa nā ʻanuʻu kikoʻī:

1. Hoʻopili ʻia ka pūhui phenyl nitro me ka sodium cyanide ma lalo o nā kūlana alkaline.

2. ʻO ka 3-phenylprop-2-ynenitril i hana ʻia i ka wā o ka hopena i loaʻa ma o ka unuhi ʻana a me ka hoʻomaʻemaʻe distillation.

ʻIke palekana:

1. Pono e hana ʻia ka 3-phenylprop-2-ynenitril ma kahi e hoʻoluliluli maikaʻi ʻia, e pale aku i ka inhalation o ka mahu a i ʻole ka pili ʻana me ka ʻili a me nā maka.

2. He mea hoʻonāukiuki paha ia i ka ʻili a me nā maka, no laila e holoi me ka wai ma hope koke o ka hoʻopili ʻana.

3. E hoʻohana i nā lako pale pilikino kūpono e like me nā maka aniani, nā mīkina lima a me nā ʻaʻahu lab ke hana.

4. Pono e mālama ʻia ka 3-phenylprop-2-ynenitril i loko o kahi pahu i hoʻopaʻa ʻia, ma kahi mamao o nā lapalapa a me nā wela kiʻekiʻe.

5. I ka wā e hoʻolei ai i ka ʻōpala, pono e mālama ʻia nā kānāwai hoʻolei kūloko.
