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.
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.

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.
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 .
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

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.
offers 128 butyl carbitol products. About 9% of these are alcohol hydroxybenzene ether, 7% are syntheses material intermediates, and 3% are dyestuff intermediates. A wide variety of butyl carbitol options are available to you, such as syntheses material intermediates, agrochemical intermediates, and flavor fragrance intermediates.
Extraction of HAuCl 4 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, distribution ratios were determined. Experiments were made at other c HCl.
Diethylene glycol butyl ether (2(2Butoxyethoxy)ethanol) is an organic compound, one of several glycol ether solvents. It is a colorless liquid with a low odour and high boiling point. It is mainly used as a solvent for paints and varnishes in the chemical industry, detergents, brewing chemicals and textile processing.. Production and Use ...
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.
An improved process was developed to produce gold with purity > % (> 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.
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 ...
