gold solvent dibutyl carbitol - skinzleather. Dibutyl carbitol which is not only stable but also low in volatility and toxicity is a suitable solvent for use in solvent extraction of gold from chloride bearing aqueous solutions. BUTYL CARBITOL. MSDS & SPECS - 2.imimg.
Jun 28, 1983· 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 using a reducing agent such as aqueous oxalic acid.
Feb 01, 2013· Some additional aspects of gold(III) extraction by dibutyl carbitol Some additional aspects of gold(III) extraction by dibutyl carbitol Mironov, Igor V. 2013-02-01 00:00:00 From changes of volumes of the aqueous and organic phases it was found that the extraction of HAuCl 4 from hydrochloric medium by dibutyl carbitol (DBC) involves co-extraction of about 6 mol of water per one mole of gold.
Butyl CARBITOL glycol ether can be considered a slower-evaporating analog of Butyl CELLOSOLVE glycol ether. It can be used in combination with Butyl CELLOSOLVE glycol ether to lower the evaporation rate and increase the hydrophobicity of the solvent package. Yet Butyl CARBITOL glycol ether offers water solubility. Typical Physical Properties
Extraction of HAuCl 4 with diethylene glycol dibutyl ether (dibutyl carbitol) was studied in the gold(III) concentration range 10 −6 −1.5 mol/L at c HCl = 1 mol/L and T = 25°C, distribution ratios were determined. Experiments were made at other c HCl.

Butyl diglyme GoldRefiningWiki. Butyl diglyme, BDG for short (also known as Dibutyl Carbitol, CAS number: 112732) is a liquid solvent that has a great affinity for gold chloride.It doesn't mix with water so one of its uses is for liquid liquid extraction of gold from solutions.
The extraction and recovery of gold from copper electrorefining slimes by leaching and solvent extraction using dibutyl carbitol (DBC) has been practiced for several decades.
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.
An improved process was developed to produce gold with purity > 99.9998% (> 5 N) from gold scraps using dibutyl carbitol (DBC) as an extractant. The extraction of gold into DBC was optimised, which showed that gold could be effectively loaded into DBC up to 190 g/L Au.
Butyl CARBITOL™ glycol ether can be considered a slower-evaporating analog of Butyl CELLOSOLVE™ glycol ether. It can be used in combination with Butyl CELLOSOLVE™ glycol ether to lower the evaporation rate and increase the hydrophobicity of the solvent package. In addition, Butyl CARBITOL™ glycol ether offers water solubility.
In the present study, the copper anode slime was leached in chloride media. Then, pregnant leach solution (PLS) was purified using solvent extraction method and Octanol-kerosene solution. HAuCl4.2L was determined as the extracted macromolecule, and separation of impurities, such as copper, iron and selenium was done in the presence of gold.
A high boiling, slow evaporating ester solvent that provides a good balance of volatility, solvency and water solubility. Introduction Butyl CARBITOL Acetate Solvent is frequently used as a coalescing solvent in waterborne coatings and provides a good balance of volatility, solvency and water solubility.
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 .
