N-Ethylaniline CAS: 103-69-5

mankhwala katundu

Madzi opanda mtundu.

Malo osungunuka -63.5 ℃ (malo ozizira -80 ℃),

powira 204.5 ℃, 83.8 ℃ (1.33kPa),

kachulukidwe wachibale 0.958 (25 ℃)

refractive index 1.5559,

flash point 85 ℃,

moto point 85 ℃ (otseguka).

Insoluble m'madzi ndi ether, sungunuka mu mowa ndi zosungunulira zambiri za organic. Ikawonetsedwa ndi kuwala kapena mpweya, imasanduka bulauni ndipo imakhala ndi fungo la aniline.

Kagwiritsidwe:

Izi zimagwiritsidwa ntchito popanga organic synthesis ndipo ndizofunikira zapakatikati pa utoto wa azo ndi utoto wa triphenylmethane; itha kugwiritsidwanso ntchito ngati wapakatikati pamankhwala abwino monga zowonjezera za mphira, zophulika, ndi zida zazithunzi.

Njira yopangira

1. Njira ya Hydrochloric acid: itani aniline hydrochloride ndi ethanol pa 180 ° C ndi 2.94MPa, tsitsani ethanol ochulukirapo ndi mankhwala a ether, kenaka onjezerani 30% NaOH ndi p-toluenesulfonyl chloride, ndikuchotsani Chemicalbook by-products ndi steamhylani distillation. , kenaka yikani sulfuric acid kuti mupeze mankhwalawo. 2. Phosphorus trichloride njira: kuchita aniline, Mowa ndi phosphorous trichloride pa 300°C ndi 9.84MPa, ndi fractionate zimene osakaniza ndi vacuum distillation kupeza N-ethylaniline.

Zambiri zamalumikizidwe
