Ethoxymethylenemalononitrile CAS: 123-06-8

Ethoxymethylenemalononitrile, tseem hu ua EMME, yog siv rau hauv ntau yam kev siv thoob plaws ntau yam lag luam vim nws muaj peev xwm ua tau ntau yam thiab ua haujlwm tau zoo. Ib qho ntawm cov kev siv tseem ceeb ntawm EMME yog hauv kev tsim cov organic rau kev npaj ntau yam tshuaj. Nws ua haujlwm ua ib qho tseem ceeb hauv kev tsim cov tshuaj, agrochemicals, thiab lwm yam tshuaj zoo. Hauv kev tshuaj lom neeg organic, EMME feem ntau siv rau hauv Knoevenagel condensation reaction los tsim cov α, β-unsaturated nitriles thiab esters. Cov khoom no muaj cov ntawv thov tseem ceeb hauv kev lag luam tshuaj vim lawv ua haujlwm ua cov khoom siv ua ntej rau kev tsim cov bioactive molecules thiab tshuaj. EMME kuj tseem tuaj yeem koom nrog Michael addition reactions, pab txhawb kev tsim cov khoom sib txawv nrog cov haujlwm biological. Ntxiv mus, Ethoxymethylenemalononitrile yog siv rau hauv kev tshawb fawb txog cov khoom siv rau kev npaj cov polymers thiab cov khoom ntxiv polymer. Nws lub peev xwm los dhau cov tshuaj polycondensation ua rau nws muaj txiaj ntsig zoo rau kev tsim cov polymers nrog cov khoom tshwj xeeb xws li kev pom tseeb ntawm lub teeb, kev ruaj khov thermal, thiab lub zog kho tshuab. Hauv kev ua liaj ua teb, EMME pom kev siv hauv kev tsim cov tshuaj tua kab tshiab thiab cov tshuaj tua kab. Los ntawm kev koom ua ke EMME rau hauv cov qauv molecular ntawm cov khoom xyaw nquag, cov kws tshawb fawb tuaj yeem txhim kho qhov ua tau zoo thiab kev xaiv ntawm cov khoom tiv thaiv qoob loo, pab txhawb rau kev ua liaj ua teb kom ruaj khov. Zuag qhia tag nrho, Ethoxymethylenemalononitrile ua lub luag haujlwm tseem ceeb ua lub hauv paus hauv kev tshuaj lom neeg organic, ua kom muaj kev sib xyaw ua ke ntawm ntau yam tshuaj nrog cov khoom muaj nqis. Nws cov ntawv thov dav dav qhia txog nws qhov tseem ceeb hauv kev tshawb fawb, kev txhim kho, thiab cov txheej txheem tsim khoom thoob plaws ntau yam kev lag luam.
