gold solvent dibutyl carbitol 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
A process for sequentially and selectively separating gold and platinum group metals from aqueous solutions containing them is disclosed. First, ruthenium and osmium are oxidised to their tetroxides and then removed from the solution. Then, gold is removed by solvent extraction preferably with dibutyl carbitol. Next, palladium and platinum are removed by solvent extraction with a dialkyl ...
Butyl diglyme, BDG for short (also known as Dibutyl Carbitol, CAS number: 112732) is a liquid solvent that has a great affinity for gold doesn''t mix with water so one of its uses is for liquid liquid extraction of gold from solutions. The gold is released later when the BDG is contacted with a solution containing, for example, oxalic acid.
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 doesn''t mix with water so one of its uses is for liquid liquid extraction of gold from solutions.
Glycol ethers are a group of solvents based on alkyl ethers of ethylene glycol or propylene glycol commonly used in paints and cleaners. These solvents typically have a higher boiling point, together with the favorable solvent properties of lowermolecular weight ethers and alcohols .
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 Octanolkerosene solution. was determined as the extracted macromolecule, and separation of impurities, such as copper, iron and selenium was done in the presence of gold.

Abstract. An approach to the problem of separating thorium from uranium in Solvent extraction process streams is described. Aqueous phosphate, oxalate, and fluoride scrub systems were compared for their ability to remove thorium from dibutyl carbitol which contained both thorium and uranium.
Extraction of precious metalsDiethylene glycol dibutyl ether is used as a solvent in Grignard reactions. It is also used as solvents in gold refining, decorative inks for ceramics and digital inks. It finds application in electrochemistry, gas absorption, extractant and high boiling reaction medium.
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. 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 coextraction of about 6 mol of water per one mole of gold.
PDF | Extraction of HAuCl4 with diethylene glycol dibutyl ether (dibutyl carbitol) was studied in the gold(III) concentration range 10−6− mol/L at c HCl = 1 mol/L and T = 25°C ...
Butyl CARBITOL glycol ether can be considered a slowerevaporating 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
Use: Eastman™ DE Solvent (Diethylene Glycol Monoethyl Ether) is a very polar, slow evaporating, water miscible solvent with a low odor. It is an active solvent for cellulose acetate butyrate, nitrocellulose, epoxy resins, and other coating materials.
Extractant for gold and uranium ores. Grade/Purity: This is reagent grade material with a minimum purity of 99%. Current Popular Applications: Users report regularly making % purity gold using this solvent . precipitated with a 10% solution of oxalic acid over a 48 hour period. This solvent .

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.
Butyl carbitol is produced through the reaction of nbutanol and ethylene oxide with an alkali catalyst. It is a chemical intermediate in the production of and piperonyl acetate, diethylene glycol dibutyl ether, diethylene glycol monobutyl ether acetate and as a solvent in high baked enamels.
Butyl Glycol Acetate is also a good solvent for urethane finishes and is a film coalescing aid for polyvinyl latex acetate. Butyl Glycol Acetate also has applications in the industry where it is a component of flexographic, gravure, and screen inks.
Butyl diglyme, also called diethylene glycol dinbutyl 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.
Product Safety Assessment: Diethylene Glycol Butyl Ether Revised: December 23, 2014 The Dow Chemical Company Page 2 of 5 back to top Product Description3,8 Butyl CARBITOL™ solvent is a clear, liquid with a mild ether odor.
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.
Jun 28, 1983· The extraction of gold with dibutyl carbitol should be carried out as a continuous countercurrent multistage process. The goldloaded 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.
