N-Ethylaniline CAS: 103-69-5

makemikari zvinhu

Mvura isina ruvara.

Kunyungudika -63.5 ℃ (inotonhora -80 ℃),

kuvira poindi 204.5℃, 83.8℃ (1.33kPa),

hukama density 0.958 (25℃)

refractive index 1.5559,

flash point 85 ℃,

nzvimbo yemoto 85 ℃ (yakavhurika).

Insoluble mumvura uye ether, inonyungudika mudoro uye yakawanda organic solvents. Kana yaiswa muchiedza kana mhepo, inokurumidza kushanduka tsvuku uye ine kunhuhwirira kweaniline.

Kushandisa:

Ichi chigadzirwa chinoshandiswa mune organic synthesis uye yakakosha yepakati kune azo dyes uye triphenylmethane dhayi; inogona zvakare kushandiswa seyepakati yemakemikari akanaka senge rubber additives, zvinoputika, uye mafoto zvinhu.

Nzira yekugadzira

1. Hydrochloric acid nzira: react aniline hydrochloride uye ethanol pa180 ° C uye 2.94MPa, disti kunze ethanol yakawandisa uye ne-product ether, wobva wawedzera 30% NaOH uye p-toluenesulfonyl chloride, uye bvisa Chemicalbook by-products by steamhylani distillation. , uye wobva wawedzera sulfuric acid kuti uwane chigadzirwa. 2. Phosphorus trichloride nzira: react aniline, ethanol uye phosphorus trichloride pa 300 ° C uye 9.84MPa, uye patsanura musanganiswa wekuita ne vacuum distillation kuti uwane N-ethylaniline.
