Phenylacetylene(CAS#536-74-3) hoʻolauna
maikaʻi
ʻO Phenacetylene kahi mea hoʻohuihui. Eia kekahi mau waiwai o ka phenylacetylene:
1. Nā waiwai kino: He wai waihoʻoluʻu ʻole ka Phenacetylene i hiki ke hoʻololi i ka mahana wela.
2. Nā waiwai kemika: Hiki i ka Phenylacetylene ke hana i nā hopena he nui e pili ana i nā paʻa kolu kalapona kalapona. Hiki iā ia ke hoʻohui i nā halogens, e like me ka hoʻohui ʻana me ka chlorine e hana i ka phenylacetylene dichloride. Hiki i ka Phenacetylene ke ho'ēmi i ka hopena, me ka hydrogen i mua o kahi catalyst e hana i ka styrene. Hiki nō hoʻi iā Phenylacetylene ke hoʻokō i ka hopena hoʻololi o nā reagents ammonia e hoʻohua i nā huahana hoʻololi.
3. Paʻa: ʻO ka paʻa kolu kalapona kalapona o ka phenylacetylene e loaʻa iā ia kahi kiʻekiʻe o ka unsaturation. ʻAʻole paʻa a paʻa i nā hopena polymerization kuʻuna. ʻO ka Phenacetylene ka mea wela loa a pono e pale ʻia mai ka hoʻopili ʻana me nā mea hoʻoheheʻe ikaika a me nā kumu hoʻāla.
ʻO kēia kekahi o nā waiwai kumu o ka phenylacetylene, nona ka waiwai hoʻohana koʻikoʻi i ka synthesis organik, ʻepekema waiwai a me nā ʻano ʻē aʻe.
ʻIke palekana
Phenacetylene. Eia kekahi ʻike palekana e pili ana i ka phenylacetylene:
1. Ka 'awa'awa: Loa'a i ka Phenylacetylene kekahi mea 'awa'awa a hiki ke komo i loko o ke kino o ke kanaka ma ka inhalation, pili me ka 'ili, a i 'ole ka 'ai 'ana. Hiki ke loaʻa nā hopena maikaʻi ʻole i ka hanu, ʻōnaehana nerve, a me ke akepaʻa i ka wā lōʻihi.
2. Pahū ahi: ʻO Phenylacetylene kahi mea hiki ke hana i kahi hui pahū me ka oxygen i ka lewa. Hiki ke alakaʻi i ke ahi a pahū paha ka ʻike ʻana i nā lapalapa ahi, nā wela kiʻekiʻe, a i ʻole nā kumu hoʻā. Pono e hōʻalo ʻia ka hoʻopili ʻana me nā mea e like me nā oxidants a me nā waikawa ikaika.
3. E pale i ka inhalation: He pilau ko ka Phenylacetylene e hiki ai ke hoonawaliwali, hiamoe, a me ka pilikia o ka hanu. Pono e mālama ʻia ka ventila maikaʻi i ka wā o ka hana ʻana a pono e pale ʻia ka inhalation pololei o nā mahu a me nā kinoea phenylacetylene.
4. Palekana pili: I ka lawelawe ʻana i ka phenylacetylene, e hoʻokomo i nā mīkina lima pale, nā maka aniani a me nā lole pale kūpono e pale aku ai i ka pili ʻana me ka ʻili a me nā maka.
5. Ka mālama ʻana a me ka mālama ʻana: Pono e mālama ʻia ka Phenylacetylene ma kahi ʻoluʻolu a maikaʻi ka makani, ma kahi mamao mai nā kumu ahi a me nā lapalapa ākea. Pono e nānā ʻia ka pahu no ke kūlana paʻa ma mua o ka hoʻohana ʻana. Pono ke kaʻina hana e hahai i nā kaʻina hana palekana no ka pale ʻana i nā huna huna a me nā koina electrostatic.
Hoʻohana a me nā ʻano hana synthesis
ʻO Phenacetylene kahi mea hoʻohuihui. Hana ʻia me ke apo benzene i hoʻopili ʻia i kahi hui acetylene (EtC≡CH).
Loaʻa i ka Phenacetylene kahi ākea o nā noi i ka synthesis organik. Eia kekahi mau hoʻohana nui:
ʻO ka hana pesticide: he mea koʻikoʻi ka phenylacetylene i ka hana ʻana o kekahi mau lāʻau pesticides i hoʻohana mau ʻia, e like me ka dichlor.
Nā noiʻi Optical: Hiki ke hoʻohana ʻia ka Phenylacetylene i nā hopena photopolymerization, e like me ka hoʻomākaukau ʻana i nā mea photochromic, nā mea photoresistive, a me nā mea photoluminescent.
ʻO nā ʻano hana synthesis o ka phenylacetylene i nā laboratories a me nā ʻoihana e like me kēia:
Acetylene pane: ma o ka arylation reaction a me ka acetylenylation reaction o ke apo benzene, ke apo benzene a me ka hui acetylene e hoʻomākaukau i ka phenylacetylene.
ʻO ka pane hoʻonohonoho hou ʻana o Enol: Hoʻopili ʻia ka enol ma ke apo benzene me ka acetylenol, a loaʻa ka hopena hoʻonohonoho hou e hana i ka phenylacetylene.
Alkylation reaction: kau ʻia ke apo benzene ma luna
