Gylcerol

The biotransformation of gylcerol trinitrate by strains of Bacillus thuringiensis/cereus or Enterobacter agglomerans (Meng et al. 1995), by strains of Pseudomonas sp., and some Entero-bacteriaceae (Blehert et al. 1997) involves the expected successive loss of nitrite with the formation of glycerol. The biotransformation of pentaerythritol tetranitrate by Enterobacter cloacae proceeds comparably with metabolism of two hydroxymethyl groups produced by loss of nitrite to the aldehyde (Binks et al. 1996). 

Antistatic additives are designed to be present on the surface of the molded part to achieve the full antistatic benefit. The types of additives used to enhance antistatic properties include quaternary ammonium salts, alkyl sulfonates or phosphate plus alkali metals, ethoxylated amines, or gylcerol esters. Antistatics are typically used at higher levels than other additives such as antioxidants. Therefore, antistatics are likely to increase light scattering, making it more difficult to achieve the higher chroma colors. 

The NAD" -dependent gylcerol dehydrogenase (GDH) [76] catalyzes the oxidation of secondary hydroxy groups in polyols to the keto function. Thus, chiral enantiomerically pure acyloins are accessible, or via enzymatic resolution chiral, enantiomerically pure... 

Light mineral oil is used in applications similar to those of mineral oil. It is used primarily as an excipient in topical pharmaceutical formulations where its emollient properties are exploited in ointment bases see Table I. It is also used in ophthalmic formulations. Light mineral oil is additionally used in oil-in-water and polyethlylene glycol/gylcerol emulsions as a solvent and lubricant in capsules and tablets as a solvent and penetration enhancer in transdermal preparations and as the oily medium used in the microencapsulation of many drugs. ... 

Plots of dT (defined as the height of die recorder deflection) against hydroxyl value (determined by the conventional phthalic anhydride method) for five gylcerol-propylene oxide condensates ranging in molecular weight between 300 and 4000 pass very near to the origin.
