What is Poly(ethylene glycol) butyl ether?
Definition
ChEBI: 2-butoxyethanol is a primary alcohol that is ethanol in which one of the methyl hydrogens is replaced by a butoxy group. A high-boiling (171℃) colourless liquid, it is used as a solvent for paints and inks, as well as in some dry cleaning solutions. It has a role as a protic solvent. It is a primary alcohol and a glycol ether.
