N-Benzyl-N-ethylaniline

1 Nws yog lub teeb daj oily kua, soluble nyob rau hauv ethanol thiab lwm yam organic solvents, insoluble nyob rau hauv dej.

2, Txoj kev tsim khoom yog tau los ntawm kev ua haujlwm ntawm ethyl aniline thiab benzyl chloride. Nyob rau hauv ib lub lauj kaub uas muaj hlau lead, ntxiv ethyl aniline, ntxiv benzyl chloride thaum txias, do rau 10 teev, thiab tom qab ntawd sov ntawm 100 ° C rau 12 teev. Tom qab ntxuav nrog sodium hydroxide tov, cov khoom tiav yog tau los ntawm lub tshuab nqus tsev distillation. Diethylaniline tuaj yeem siv los ua cov khoom siv raw. Cov molar piv ntawm diethylaniline rau benzyl chloride yog 2: 1. Ntxiv 1% ntawm cov khoom noj ntawm diethylaniline rau catalyze nws nrog iodine, react ntawm 150 ℃ rau 20h, thiab nqus distill kom tau cov khoom tiav.

3, Siv cov xim nruab nrab. Siv los ua acidic teeb ntsuab SF thiab lwm yam xiav dyes.
