Butyl Diglyme | MSDS Butyl Diglyme | Silver Fern Chemical

Butyl diglyme, also called diethylene glycol di-n-butyl ether, is a polar aprotic solvent with excellent thermal and chemical stability. Glymes, or glycol diethers, are a widely used family of saturated polyethers for increasing anion reactivity in a given system, thus affecting selectivity and reaction rates.

MINATAUR™: the Mintek alternative technology to gold refining

solvent extraction (SX) process for the refining of gold using dibutyl carbitol (DBC) as the extractant. Although the selective extraction of gold from chloride media using DBC is favourable, stripping requires direct precipi-tation of gold from the loaded organic phase, resulting in high organic losses. The high aqueous solubility of DBC also requires distil-lation of the raffinate to recover ...
