Tsis yaj hauv dej thiab ether, yaj hauv cawv thiab feem ntau cov kuab tshuaj organic. Thaum raug lub teeb lossis raug cua, nws sai sai hloov xim av thiab muaj ntxhiab tsw aniline.

Kev Siv:

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 ua ib qho nruab nrab rau cov tshuaj zoo xws li cov roj hmab ntxiv, cov khoom tawg, thiab cov ntaub ntawv thaij duab.

Txoj kev tsim khoom

1. Txoj kev Hydrochloric acid: sib xyaw aniline hydrochloride thiab ethanol ntawm 180 ° C thiab 2.94 MPa, distill cov ethanol thiab cov khoom seem ether, tom qab ntawd ntxiv 30% NaOH thiab p-toluenesulfonyl chloride, thiab tshem tawm cov khoom seem Chemicalbook los ntawm kev sib xyaw ua pa diethylaniline, thiab tom qab ntawd ntxiv sulfuric acid kom tau txais cov khoom. 2. Txoj kev Phosphorus trichloride: sib xyaw aniline, ethanol thiab phosphorus trichloride ntawm 300 ° C thiab 9.84 MPa, thiab faib cov tshuaj sib xyaw los ntawm kev sib xyaw ua pa kom tau txais N-ethylaniline.
