Txoj kev tsim khoom:
1. Txoj kev alkylation ethanol: Sau lub reactor fluidized bed nrog lub peev xwm ntawm 400 qhov nrog H3PO4-SiO2 catalyst, nrog thaj tsam sab hauv ntawm 400m2 / g, thiab cov ntsiab lus H3PO4 ntawm 10%. Hauv lub tshuab cua sov quartz ntsia rau hauv qab ntawm lub txaj fluidized, 110 qhov ntawm cov khoom sib xyaw ntawm cov khoom sib xyaw hauv qab no, uas yog 66% o-toluidine thiab 34% ethanol [piv 1: 1.2 (molar piv)] tau evaporated ntawm 250 ° C. Lub txaj fluidized yog cua sov rau 330 ° C nrog Chemicalbook. 108 qhov ntawm condensate tau txais ib teev, uas cov ntsiab lus ntawm N-ethyl o-toluidine yog 60.0 qhov, cov ntsiab lus ntawm N, N-diethyl o-toluidine yog 10.7 qhov, thiab cov ntsiab lus ntawm o-toluidine yog 14.5 qhov. Tus nqi hloov pauv yog 80%, 82.5% ntawm cov tshuaj o-toluidine uas tau hloov pauv mus rau hauv N-ethyl o-toluidine, thiab 13.1% hloov pauv mus rau hauv N, N-diethyl o-toluidine. Alkylating agent ethanol 5% hloov pauv mus rau ethylene.

2. Txoj kev alkylation Bromoethane? Ntxiv 40mL (0.37mol) ntawm o-toluidine thiab 14mL (0.185mol) ntawm bromoethane rau hauv lub raj mis peb-caj dab 250mL. Tom qab cua sov thiab rov ua dua rau 2 teev, nws raug alkalized nrog 40% sodium hydroxide kua. Tom qab ntawd ntxiv 18.5g (0.136mol) ntawm zinc chloride thiab 20mL dej hauv Chemicalbook kua, thiab do rau 2.5 teev. Cov khoom lim tau raug rho tawm tas li nrog petroleum ether hauv Soxhlet apparatus, cov extract tau ntxuav nrog dilute ammonia thiab dej distilled, petroleum ether tau evaporated, cov kua seem tau distilled hauv qab qhov siab txo qis, thiab 105 ~ 110 ℃ (4.67kpa) distillate tau sau kom tau 21.1g Cov khoom tiav, suav ua bromoethane, muaj cov txiaj ntsig ntawm 85%.
