Hu, Zhandong et al. published their research in Shandong Huagong in 2021 | CAS: 111-77-3

2-(2-Methoxyethoxy)ethanol (cas: 111-77-3) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. At room temperature, ethers are pleasant-smelling colourless liquids. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil.Formula: C5H12O3

Study on synthesis of yellowing resistant and durable antistatic polyurethane composites was written by Hu, Zhandong;Zhang, Shuohao;Kang, Yiyang;Bao, Lixia;Wang, Jiliang. And the article was included in Shandong Huagong in 2021.Formula: C5H12O3 This article mentions the following:

In this paper, the intermediate product 1-(methyl-di(oxyethylene))-3-ethylimidazolium bromide was prepared by N-alkylation using diethylene glycol Me ether, sodium bromide, imidazole and bromoethane as raw materials. ([DMEEIM][Br]) ionic liquid The hydrophilic ionic liquid 1-(methyl-di(oxyethylene))-3-ethylimidazolium tetrafluoroborate ([DMEEIM][BF4]) was obtained by ion exchange. The target product after separation and purification was characterized by FT-IR and 1H-NMR, and its elec. conductivity was measured. The results showed that its elec. conductivity could reach 367 μS/cm. Using hexamethylene diisocyanate (HDI), polytetrahydrofuran ether glycol 2000 (PTMEG2000) and 1,4-butanediol (BDO) as raw materials, a solution polymerization method was used to obtain a yellowing-resistant polyurethane. The prepared ionic liquid was blended with polyurethane to obtain a permanent antistatic polyurethane composite material with yellowing resistance. Differential scanning calorimetry (DSC) and thermogravimetric anal. (TGA) were used to characterize the samples, and their tensile strength, elongation at break and surface resistivity were measured. The results showed that the obtained polyurethane film had excellent resistance to yellowing and permanent static resistance, and its surface resistivity reached 107 Ohm·sq-1. In the experiment, the researchers used many compounds, for example, 2-(2-Methoxyethoxy)ethanol (cas: 111-77-3Formula: C5H12O3).
