Aug 19, 2015· Compare Dibutyl Carbitol (DBC), aka Butyl Diglyme (BDG), with DiEthyl Malonate (DEM). DEM, a more recent organic solvent for AuCl 3, has a number of benefits over the other more widely popular BDG. - less soluble in water than BDG. - denser than water as opposed to BDG which is less dense.
An analytical standard of 1 µL/mL butyl carbitol and butyl carbitol acetate in the desorbing solvent of 5:95 methanol:methylene chloride with 0.25 µL/mL n-hexanol internal standard, analyzed on a 60-meter DB-wax column. 3.5.3 Peak areas are measured by an integrator or other suitable means.
The extraction of gold with dibutyl carbitol should be carried out as a continuous counter-current multistage process. The gold-loaded solvent may then be scrubbed with dilute hydrochloric acid to remove base metal impurities and gold may be reduced directly from the scrubbed solvent …
Apr 11, 2006· One of these commercially proven applications uses butyl diglyme (dibutyl carbitol, E444) to extract gold(III) chloride from acidic aqueous solutions. Sources of gold include various ores, concentrates, anode slimes, cathode sludges, electrolytic plating operations and gold coated electronic parts.
DEGBE is also a chemical intermediate for the synthesis of diethylene glycol monobutyl ether acetate, diethylene glycol dibutyl ether, and piperonyl acetate, and as a solvent in high baked enamels. Other applications of DEGBE are as a dispersant for vinyl chloride resins in organosols, a diluent for hydraulic brake fluids, and a mutual solvent ...
