3-(3,4-Dimethoxyphenyl)propan-1-ol (cas: 3929-47-3) belongs to ethers. 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. At room temperature, ethers are pleasant-smelling colourless liquids.

Miscibility and hydrogen bonding in blends of poly(ethylene oxide) and kraft lignin was written by Kadla, John F.;Kubo, Satoshi. And the article was included in Macromolecules in 2003.Reference of 3929-47-3 This article mentions the following:

In this study we have prepared poly(ethylene oxide)-lignin blends using thermal mixing. Miscible blends were observed over the entire blend ratio. A m.p. depression, comparable to results obtained from phenoxy/PEO blends, and a neg. deviation of the glass temperature (Tg) from the weight-average values was observed The effect of the binary interaction parameter, χ, on Tg was analyzed. Satisfactory prediction of the Tg-composition curve was obtained, in which specific intermol. interactions exist. FT-IR analyses revealed a strong hydrogen bond between the aromatic hydroxyl proton and the ether oxygen in PEO. In the experiment, the researchers used many compounds, for example, 3-(3,4-Dimethoxyphenyl)propan-1-ol (cas: 3929-47-3Reference of 3929-47-3).
