Study on the conversion of acrylic C=C double bonds during dark reaction after UV curing using infrared spectroscopy was written by Ma, Guo-zhang;Wu, Jian-bing;Xu, Bing-she. And the article was included in Guangpuxue Yu Guangpu Fenxi in 2010.Safety of Diethyleneglycoldiacrylate This article mentions the following:
IR spectroscopy was used to determine 1 648-1 589 cm-1 characteristic absorption peak area so as to study the conversation of acrylic C=C double bonds after UV curing. The effects of photoinitiators, active diluents and UV curing resins on the conversion of C=C double bonds were also studied. 40%-85% Of C=C double bonds were conversed during dark reaction after 45 s UV curing. Dark reaction will be changed gently after 1.75 h, but 95% conversion of C=C double bonds needed more than 24 h. The rates of polymerization and conversation were affected by photoinitiators, the concentration of photoinitiator, oxygen inhibition, and C=C functional groups of active diluents. The rate of polymerization was affected by the C=C functional groups and types of UV curing resins, but conversation was not. In the experiment, the researchers used many compounds, for example, Diethyleneglycoldiacrylate (cas: 4074-88-8Safety of Diethyleneglycoldiacrylate).
Diethyleneglycoldiacrylate (cas: 4074-88-8) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Safety of Diethyleneglycoldiacrylate
