N-Ethylaniline CAS: 103-69-5

iimpawu zeekhemikhali

Ulwelo olungenambala.

Indawo yokunyibilika -63.5℃ (indawo yokukhenkceza -80℃),

indawo yokubila 204.5℃, 83.8℃ (1.33kPa),

Uxinzelelo olunxulumeneyo 0.958 (25℃)

isalathiso se-refractive 1.5559,

indawo edanyazayo 85℃,

indawo yomlilo 85℃ (evulekileyo).

Ayinyibiliki emanzini nakwi-ether, enyibilikayo etywaleni kunye nakwizinyibilikisi ezininzi eziphilayo. Xa ibonakaliswe ekukhanyeni okanye emoyeni, ijika ngokukhawuleza ibe mdaka kwaye ibe nephunga le-aniline.

Ukusetyenziswa:

Le mveliso isetyenziswe kwi-organic synthesis kwaye ibalulekile phakathi kwe-azo dyes kunye ne-triphenylmethane dyes; isenokusetyenziswa njengendawo ephakathi kwiikhemikhali ezintle ezifana nezongezo zerabha, iziqhushumbisi, kunye nemathiriyeli yokufota.

Indlela yokuvelisa

1. Indlela ye-Hydrochloric acid: phendula i-aniline hydrochloride kunye ne-ethanol kwi-180 ° C kunye ne-2.94MPa, i-distill ngaphandle kwe-ethanol engaphezulu kunye nemveliso ye-ether, uze udibanise i-30% ye-NaOH kunye ne-p-toluenesulfonyl chloride, kwaye ususe i-Chemicalbook nge-products nge-steamhylani distillation. , kwaye emva koko wongeze i-asidi ye-sulfuric ukufumana imveliso. 2. Indlela ye-Phosphorus trichloride: phendula i-aniline, i-ethanol kunye ne-phosphorus trichloride kwi-300 ° C kunye ne-9.84MPa, kwaye uhlukanise umxube wokuphendula nge-vacuum distillation ukuze ufumane i-N-ethylaniline.
