Glycolic acid is an attractive raw material which is used as a dyeing and tanning agent in the textile industry, a flavoring agent and preservative in the food processing industry, and a skin care agent in the pharmaceutical industry. It is also utilized for the production of polyglycolic acid and other biocompatible copolymers. Glycolic acid can be isolated from natural sources, such as sugarc...

The lactic acid content of gari, was determined by pH titration to be about 10 g lactic acid/kg gari. As the size of the gari particles increased from 400 to >1000 lm their total cyanide content increased from 5 to 21 ppm. The acetone cyanohydrin content of gari samples exposed to ambient laboratory conditions of temperature and relative humidity gradually decreased by 58% in 38 weeks whereas l...

Polymethyl methacrylate (PMMA) can be considered the queen of resins, because it is the most beautiful of synthetic resins. Making use of its superior transparency, weather resistance and other characteristics, the demand for its use in signboards and displays, lighting equipments, automotive parts, construction related materials and the like has increased. Recently, we have seen a rapid expans...

The rapid recovery of the Winchcombe meteorite offers a valuable opportunity to study soluble organic matter (SOM) profile in pristine carbonaceous astromaterials. Our interests biologically relevant molecules, amino acids—monomers protein, and most prevalent meteoritic organics—polycyclic aromatic hydrocarbons (PAHs) are addressed by analyzing solvent extracts stone using gas chromatography ma...
