PTMEG, Polytetrahydrofuran, also called poly(tetramethylene ether) glycol or poly(tetramethylene oxide), is a linear diols with formula (C4H8O)nH2O. It can be viewed as a polymer of tetrahydrofuran, or as the polyether derived from 1,4-butanediol. The product is commercially available as polymers of low average molecular weights, between 250 and 3000 daltons. In this form it is […]

Butyl Di Glycol
Butyl di glycol also known as BDG, butyl dioxitol and diethylene glycol monobutyl ether, is a colourless, clear liquid with a faint characteristic odour, and molecular formula C8H18O3, CAS: 112-34-5. It has a flash point of 105 °C and a specific gravity of 0.955.
It is soluble in water and miscible with many common solvents, and also has low volatility and a high boiling point. These are the factors that make butyl di glycol most useful in the paint industry.
Butyl Di Glycol Chemical Structure Composition.
Butyl di glycol is one of the co-products formed when ethylene oxide is reacted with n-butanol using a catalyst.
Butyl di glycol is most commonly used in the coatings and paint industries where its low volatility and high boiling point have seen it widely accepted as a flow promoter for baking finishes such as melamine, urea, phenol, or epoxy resin composites. It is also widely used in stove enamels as it has a high evaporation number which means that the enamel properties can be improved without it affecting the drying time. It also has a role in air-drying paints as it increases “brushability”.
Butyl di glycol is also found in the printing industry where it is a solvent for printing inks, and is also a starting material in the production of butyl diglycol acetate.
