N-Benzyl-N-ethylaniline

1 Nws yog cov kua roj daj daj, soluble hauv ethanol thiab lwm cov kuab tshuaj organic, insoluble hauv dej.

2, Txoj kev tsim khoom tau los ntawm kev sib xyaw ethyl aniline thiab benzyl chloride. Hauv lub lauj kaub uas muaj cov hlau lead, ntxiv ethyl aniline, ntxiv benzyl chloride thaum txias, do rau 10 teev, thiab tom qab ntawd khaws cia kom sov ntawm 100 ° C rau 12 teev. Tom qab ntxuav nrog sodium hydroxide kua, cov khoom tiav lawm tau los ntawm kev nqus tsev distillation. Diethylaniline kuj tseem siv tau ua cov khoom siv raw. Qhov piv ntawm diethylaniline rau benzyl chloride yog 2: 1. Ntxiv 1% ntawm cov khoom noj ntawm diethylaniline los ua kom nws nrog iodine, sib xyaw ntawm 150 ℃ rau 20 teev, thiab nqus tsev distillation kom tau txais cov khoom tiav lawm.

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