Diethyleneglycoldiacrylate (cas: 4074-88-8) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Quality Control of Diethyleneglycoldiacrylate

Synthesis of an oil absorbent polymer particle with core-shell structure was written by Yang, Fajie;Li, Guoping;Zhang, Zhiheng;Cheng, Lei;Liu, Weili;Liu, Shaozhu. And the article was included in Youqitian Huanjing Baohu in 2014.Quality Control of Diethyleneglycoldiacrylate This article mentions the following:

The core structure of absorbent polymer particle was synthesized by suspension polymerization using Bu acrylate and n-laurylacrylate as monomers, diethylene glycol diacrylate as crosslinking agent, 2,2′-Azobis (2-methylpropionitrile) as initiator. Then, the shell structure was synthesized at the outer surface of the polymer particle using divinylbenzene and phenylethylene as monomers. The effects of the ratio of monomer amounts of core to that of shell, the category and amount of crosslinking agent and initiation temperature on the absorbent ability were studied. The oil absorbent polymer particle with core-shell structure was synthesized with the absorption capacity of 29 g/g. Saturation absorption time of the absorbent polymer particle with core-shell was 3 min, and it was markedly faster than that without core-shell structure. In the experiment, the researchers used many compounds, for example, Diethyleneglycoldiacrylate (cas: 4074-88-8Quality Control of Diethyleneglycoldiacrylate).
