Txoj kev tsim khoom:
Nws tau txais los ntawm cov tshuaj tiv thaiv ntawm aniline nrog benzoic acid.Cov benzoic acid qhuav thiab cov evaporated aniline tshiab tau tshwm sim ntawm 180-190 ℃ rau 2h, thiab tom qab ntawd qhov kub tau nce mus rau 225 ℃.Thaum pib, dej yog evaporated nyob rau hauv cov txheej txheem tshuaj tiv thaiv, ces aniline yog evaporated, thiab thaum kawg tag nrho cov feem yog evaporated.Cov feem evaporated tom qab 255 ℃ yog txias, solidified thiab hauv av kom tau cov khoom lag luam grey crude.Cov khoom nyoos yog ntxuav nrog dilute hydrochloric acid kom tshem tawm cov seem aniline, ntxuav nrog dej, thiab tom qab ntawd ntxiv nrog sodium hydroxide tov kom tshem tawm cov benzoic acid ntxiv.Thaum kawg, cov khoom ua kom zoo yog tau los ntawm kev ntxuav, lim, ziab thiab recrystallization nrog ethanol.
