Khoom Description
Kev siv ntawm 99.5% Ethylene Carbonate:
1. Ethylene carbonate yog dav siv los ua cov kuab tshuaj nyob rau hauv cov electrolyte ntawm lithium ion roj teeb.
2. Nws yog siv los ua ib tug polar aprotic hnyav nyob rau hauv ntau yam organic tshuaj. Nws tuaj yeem yaj ntau yam ntawm cov organic tebchaw thiab feem ntau siv hauv cov tshuaj tiv thaiv xws li alkylations, acylations, thiab condensations.
3. EC tuaj yeem ua polymerized los ua poly (ethylene carbonate), uas yog biodegradable polymer. Cov polymer no muaj peev xwm siv tau rau hauv ntim, cov ntaub ntawv biomedical, thiab lwm qhov chaw uas xav tau biodegradability.
