An alternative approach for quantification of glyceraldehyde and dihydroxyacetone as trimethylsilyl derivatives by GC-FID. Carbohydr Res 2019; 487:107885.

Abstract
A method for quantification of glyceraldehyde (GA), dihydroxyacetone (DHA) and glycerol (GLY) by gas chromatography coupled to a flame ionization detector (GC-FID) involving one-step derivatization into trimethylsilyl ethers is presented. In pyridine, DHA and GA showed predominant peaks assigned to dimeric structures and smaller peaks corresponding to the monomers. The later were identified by GC-MS as their completely derivatized molecules and were useful for construction of calibration curves with high linear correlation. On the other hand, DHA dimers were completely dissociated in water but GA dimers remained whereas with both, intermediates peaks arose which were associated to hydrated trymethyil silyl species. A calibration approach involving the sum of areas of most relevant peaks associated to aqueous solutions of GA and DHA was developed. Replicates measurements of a problem solution were in accordance with the results obtained by a well stablished HPLC technique. The coefficient of variation was below 5% for GLY and below 12% for GA and DHA. Compared with the HPLC method, the new GC-FID method presented a similar limit of quantification in the case of GA whereas for GLY and DHA a one-order-of-magnitude increase of sensitivity was achieved. TMS derivatives of GA and DHA without prior oximation enable a useful technique to study the equilibrium of the different tautomeric forms in solution.

Abstract
Biodiesel is one of the most attractive sources of clean energy. It is produced by the transformation of vegetable oils with up to 10% formation of glycerol as a by-product. Therefore, development of new approaches for processing bio-glycerol into such value-added chemical compounds as solketals is necessary. Thus, various six- and five-membered cyclic compounds can be prepared by acetalization of glycerol with aldehyde or ketone. The resulting glycerol oxygenates are excellent fuel additives that increase viscosity, octane or cetane number, and stability to oxidation. In addition, these products significantly reduce carbon monoxide emissions from standard diesel fuel. In this review, we highlight recent advances in the glycerol valorization for the sustainable production of bio-additives. The review includes a discussion of the innovative and potential catalysts to produce solketals.

Abstract
One of the major ecological concerns associated with biodiesel production is the generation of waste/crude glycerol during the trans-esterification process. Purification of this crude glycerol is not economically viable. In this context, the development of an efficient and economically viable strategy would be biotransformation reactions converting the biodiesel derived crude glycerol into value added chemicals. Hence the process ensures the sustainability and waste management in biodiesel industry, paving a path to integrated biorefineries. This review addresses a waste to wealth approach for utilization of crude glycerol in the production of value added chemicals, current trends, challenges, future perspectives, metabolic approaches and the genetic tools developed for the improved synthesis over wild type microorganisms were described.
