Detection of Adulteration of Glycerol with Diethylene Glycol by Infrared Spectroscopy

چکیده
Glycerol is a popular alcohol used within the food, pharmaceutical, and personal care industry. Glycerol (or glycerine) is listed in over 2,000 products, such as toothpaste, mouthwash, and pain relief medication due to its desirable properties to act as a humectant, preservative, and lubricant. It is prepared from fats and oils and also as a by-product from biofuel production. Demand for glycerol is expected to increase by 6.3% to $2.1 billion within the next four years, with North America and Western Europe being the largest suppliers, accounting for 64% of the market.

Diethylene Glycol-Mediated Synthesis of Nano-Sized Ceria (CeO2 )Catalyst
Nano-crystalline particles of CeO2 have been synthesized by a low temperature chemical precipitation method. The precursor materials used in this research were Ce(NO3)3.6H2O, NaOH and diethylene glycol as surfactant. X-ray powder diffraction results showed that face centered cubic CeO2 nanoparticles with crystalline size in nanometer scale were formed. Scanning electron microscopy measurement s...
متن کاملQuantitative determination of diethylene glycol contamination in pharmaceutical products.
A simple, rapid, and reliable method was developed for the quantitative determination of diethylene glycol (DEG) in pharmaceutical products using capillary gas chromatography with flame ionization detection. The method uses ethylene glycol as internal standard and allows for the separation of propylene glycol and DEG. The assay was linear in a DEG concentration range between 1.0 and 10.00 mg/mL...
