Chemical Properties:kua tsis muaj xim. Melting point -63.5 ° C (kwv yees -80 ° C), boiling point 204.5 ° C, 83.8 ° C (1.33kPa), txheeb ze ceev 0.958 (25 ° C), 0.9625 (2Chemicalbook0 ° C), refractive index 1.5559, flash taw tes 85 ° C, ignition point 85 ° C (qhib mis). Insoluble hauv dej thiab ether, soluble hauv cawv thiab feem ntau cov kuab tshuaj organic. Nws yuav tig xim av sai sai thaum raug lub teeb lossis raug huab cua, nrog cov ntxhiab tsw ntawm aniline.

Kev siv:

1) Cov khoom no yog siv rau hauv cov organic synthesis thiab yog ib qho tseem ceeb nruab nrab rau azo dyes thiab triphenylmethane dyes; nws kuj tseem siv tau los ua ib qho nruab nrab rau cov tshuaj zoo xws li roj hmab additives, explosives, thiab cov ntaub ntawv yees duab.

2) Siv los ua tshuaj tua kab thiab dye intermediates, roj hmab accelerators, thiab lwm yam.

3) Organic Synthesis. Dye intermediates.

Txoj kev tsim khoom:

1. Cov txheej txheem hydrochloric acid aniline hydrochloride thiab ethanol yog reacted ntawm 180 ° C thiab 2.94MPa, ntau tshaj ethanol thiab by-product ether yog distilled, 30% NaOH thiab p-toluenesulfonyl chloride yog ntxiv, thiab cov by-product diethyl raug tshem tawm. los ntawm chav distillation Aniline thiab sulfuric acid tuaj yeem muab ntxiv kom tau txais cov khoom.

2. Phosphorus trichloride txoj kev Aniline, ethanol thiab phosphorus trichloride yog reacted ntawm 300 ° C thiab 9.84MPa, thiab cov tshuaj tiv thaiv sib tov yog fractionated los ntawm lub tshuab nqus tsev distillation kom tau N-ethylaniline.
