Iindidi ezinxulumeneyo:ii-reagents kunye nezongezelelo; iihydrocarbons ezinevumba elimnandi; abaphakathi imidibaniso yeekhemikhali; izixhobo zekhemikhali ekrwada; iimpahla ezingekasilwa; izinto eziphilayo zekhemikhali ekrwada; imichiza ephilayo; IziPhakathi zeDayi kunye neePigments

Iimpawu zekhemikhali:indawo ebilayo 218 ° C, 95.5 ° C / 1.3kPa, ingxinano 0.938, refractive index 1.5470, flash point 88 °C.

Usebenzisa:Umbindi weYoulesan.

Isetyenziswa kwidayi, amayeza kunye nezinye izinto eziphilayo

Indlela yokuvelisa :
1. Indlela ye-Ethanol alkylation: Gcwalisa i-reactor ye-fluidized bed kunye nomthamo weengxenye ze-400 kunye ne-H3PO4-SiO2 catalyst, kunye nommandla wangaphakathi we-400m2 / g, kunye nomxholo we-H3PO4 we-10%. Kwi-evaporator ye-quartz efakwe kwindawo engezantsi yombhede owenziwe ngamanzi, iinxalenye ezili-110 zomxube wolu hlobo lulandelayo, oko kukuthi i-66% i-o-toluidine kunye ne-34% ye-ethanol [umlinganiselo 1: 1.2 (umlinganiselo we-molar)] yakhutshwa ngumphunga kwi-250 ° C. . Ibhedi efakwe amanzi ifudunyezwe kwi-330 ° C nge-Chemicalbook. Iingxenye ze-108 ze-condensate zifunyenwe ngeyure, apho umxholo we-N-ethyl o-toluidine yi-60.0 iinxalenye, umxholo we-N, N-diethyl o-toluidine yi-10.7 iinxalenye, kunye nomxholo we-o-toluidine ngamacandelo angama-14.5. Izinga lokuguqulwa kwe-80%, i-82.5% ye-o-toluidine esabelayo iguqulwa ibe yi-N-ethyl o-toluidine, kwaye i-13.1% iguqulwa ibe yi-N, N-diethyl o-toluidine. I-alkylating agent ethanol i-5% iguqulwa ibe yi-ethylene.

2. Indlela ye-Bromoethane alkylation? Yongeza i-40mL (0.37mol) ye-o-toluidine kunye ne-14mL (0.185mol) ye-bromoethane kwi-250mL yeflask enentamo ezintathu. Emva kokufudumeza kunye ne-refluxing ye-2h, i-alkalized kunye ne-40% yesisombululo se-sodium hydroxide. Emva koko wongeza i-18.5g (0.136mol) ye-zinc chloride kunye ne-20mL yamanzi kwisisombululo se-Chemicalbook, kwaye ugxobhoze i-2.5h. Isiqina esihluziweyo sakhutshwa ngokuqhubekayo nge-ether yepetroleum kwisixhobo se-Soxhlet, isicatshulwa sahlanjwa nge-ammonia edibeneyo kunye namanzi adibeneyo, i-ether ye-petroleum yaba ngumphunga, ulwelo olushiyekileyo lwachithwa phantsi koxinzelelo olucuthiweyo, kunye ne-105 ~ 110℃ (4.67kpa) i-distillate yaqokelelwa ukufumana i-21.1g Imveliso egqityiweyo, ebalwa njenge-bromoethane, inesivuno se-85%.

Udidi:Inetyhefu
Ukutsha kunye neempawu ezinobungozi:ezinokutsha; ukutsha kubola igesi enetyhefu yenitrogen oxide
Ugcino kunye neempawu zothutho:i-warehouse ingena umoya, ubushushu obuphantsi kwaye bomile; igcinwa kwaye ithuthwe ngokwahlukileyo kwii-oxidants, iiasidi, kunye nokutya
I-arhente yokucima:carbon dioxide, ugwebu, umgubo owomileyo, isanti
