Txoj kev tsim khoom:
1. Ethanol alkylation method: Sau lub txaj fluidized reactor nrog lub peev xwm ntawm 400 qhov chaw nrog H3PO4-SiO2 catalyst, nrog thaj tsam sab hauv ntawm 400m2 / g, thiab H3PO4 cov ntsiab lus ntawm 10%. Nyob rau hauv lub quartz evaporator ntsia nyob rau hauv qis ib feem ntawm lub fluidized txaj, 110 qhov chaw ntawm ib tug sib tov ntawm cov nram qab no muaj pes tsawg leeg, namely 66% o-toluidine thiab 34% ethanol [ ratio 1: 1.2 (molar ratio)] yog evaporated ntawm 250 ° C. . Lub txaj fluidized yog rhuab mus rau 330 ° C nrog Chemicalbook. 108 qhov chaw ntawm condensate tau txais ib teev, ntawm cov ntsiab lus ntawm N-ethyl o-toluidine yog 60.0 qhov chaw, cov ntsiab lus ntawm N, N-diethyl o-toluidine yog 10.7 qhov chaw, thiab cov ntsiab lus ntawm o-toluidine yog 14.5 qhov chaw. Kev hloov pauv tus nqi yog 80%, 82.5% ntawm reacted o-toluidine hloov mus rau N-ethyl o-toluidine, thiab 13.1% hloov mus rau N, N-diethyl o-toluidine. Alkylating tus neeg sawv cev ethanol 5% hloov mus rau ethylene.

2. Bromoethane alkylation txoj kev? Ntxiv 40mL (0.37mol) ntawm o-toluidine thiab 14mL (0.185mol) ntawm bromoethane rau hauv 250mL peb-caj dab. Tom qab cua sov thiab refluxing rau 2h, nws yog alkalized nrog 40% sodium hydroxide tov. Tom qab ntawd ntxiv 18.5g (0.136mol) ntawm zinc chloride thiab 20mL dej hauv Chemicalbook tov, thiab do rau 2.5h. Cov khoom lim tau raug rho tawm tsis tu ncua nrog roj av ether hauv Soxhlet apparatus, cov extract tau ntxuav nrog dilute ammonia thiab dej distilled, roj av ether yog evaporated, cov kua residual distilled nyob rau hauv txo siab, thiab 105 ~ 110 ℃ (4.67kpa) distillate tau sau kom tau 21.1g Cov khoom tiav, suav ua bromoethane, muaj txiaj ntsig ntawm 85%.

Qeb:Tshuaj lom
Flammability thiab phom sij yam ntxwv:nplaim taws; combustion decomposes tshuaj lom nitrogen oxide roj
Kev khaws cia thiab kev thauj mus los yam ntxwv:lub warehouse yog ventilated, tsis kub thiab qhuav; nws yog khaws cia thiab thauj cais los ntawm oxidants, acids, thiab zaub mov
Extinguishing agent:carbon dioxide, ua npuas ncauj, hmoov qhuav, xuab zeb
