DEA (Diethylamine)

Tshuaj lom neeg

nws yog ib yam kua tsis muaj xim, volatile flammable nrog ib qho tsw ntawm ammonia muaj zog. Nws sib xyaw nrog dej, ethanol, ether thiab lwm yam organic solvents.

Kev Siv:

Diethylamine yog ib qho tshuaj yaj thiab cov khoom siv raw tshuaj nruab nrab. Nws tuaj yeem siv los npaj cov tshuaj xws li procaine, chloroquine, nicosamid, colamin thiab sulfonamides. Nws kuj tseem siv tau los tsim cov tshuaj tua kab, cov xim, cov roj hmab vulcanization accelerators, thiab lwm yam. Cov neeg sawv cev ua cov ntxhia (sulfur thiab nitrogen No. 9), cov khoom siv textile, cov tshuaj tua kab mob, cov tshuaj tiv thaiv corrosion, cov tshuaj tiv thaiv polymerization thiab cov tshuaj tiv thaiv khov, thiab lwm yam.

txoj kev tsim khoom

Txoj kev ua kom cov pa roj theem catalysis sib xyaw cov pa roj theem ethanol, ammonia thiab hydrogen ntawm qhov sib piv ntawm 1: 0.8: 1.5 (mol), thiab nkag mus rau hauv thawj lub reactor nruab nrog lub catalyst tooj liab-nickel tom qab preheating (170-180 ° C), ntawm 195-200 ° C Cov tshuaj tiv thaiv catalytic roj-theem yog nqa tawm ntawm 170-175 ° C, thiab tom qab ntawd nws nkag mus rau hauv lub reactor thib ob Chemicalbook nrog lub catalyst tooj liab-nickel rau kev sib xyaw ua ke, thiab raug txo ntawm 170-175 ° C kom tshem tawm cov khoom tsis huv xws li acetonitrile. Cov roj tshuaj tiv thaiv yog condensed kom sau mono-, di-, triethylamine, ethanol thiab lwm yam kua sib xyaw, uas tom qab ntawd raug rau kev sib xyaw ua ke thiab kev kho kom raug, thiab 54-57 ° C feem yog txiav rau hauv cov khoom tiav ntawm diethylamine. Nws cov ntsiab lus tuaj yeem ncav cuag ntau dua 95%, thiab me me ntawm triethylamine tuaj yeem tau txais tib lub sijhawm,
