Optimization of Hydrogenolysis of Glycerol to 1,2-Propanediol

Organic Process Research & Development, 2013
Based on statistical experimental design methodology, the single-response optimization of technological parameters of glycerol hydrogenolysis to 1,2-propanediol was performed. The independent factors (technological parameters) considered were the following: hydrogenolysis temperature, glycerol concentration in water, concentration of catalyst, and ...

Excess molar volumes of (water + 1,2-propanediol), (methanol + 1,2-propanediol), and (water + methanol + 1,2-propanediol) at 283.15 K, 298.15 K, and 303.15 K

The Journal of Chemical Thermodynamics, 1990
Abstract The excess molar volumes VmE of (water + 1,2-propanediol), (methanol + 1,2-propanediol), and (water + methanol + 1,2-propanediol) have been measured at 283.15 K, 293.15 K, and 303.15 K by using a vibrating-tube densimeter. The values of VmE are all negative over the entire range of mole fractions.

The Wrappers of the 1,2-Propanediol Utilization Bacterial Microcompartments

2018
The propanediol utilization bacterial microcompartments are specialized protein-based organelles in Salmonella that facilitate the catabolism of 1,2-propanediol when available as the sole carbon source. This smart prokaryotic cell organelle compartmentalizes essential enzymes and substrates in a volume of a few attoliters compared to the femtoliter ...

Catalytic dehydration of 1,2-propanediol into propanal

Applied Catalysis A: General, 2009
Abstract Vapor-phase catalytic dehydration of 1,2-propanediol was investigated over several catalysts, such as acidic oxides and supported heteropoly acids. These acids catalyze the dehydration of 1,2-propanediol to produce propanal. In particular, silica-supported silicotungstic acid showed the highest catalytic activity in the formation of propanal.

Conformation and hydrogen bond in 1,2-propanediol

Journal of Molecular Spectroscopy, 1981
Abstract The high-resolution microwave spectrum of two conformations, each with an internal hydrogen bond has been observed for the four possible H D isotopic species of 1,2-propanediol. In both rotamers the hydroxyl in position 1 acts as proton donor to the oxygen in position 2, whose hydrogen is trans with respect to the C 1 C 2 bond. In
