3-Hydroxy-propanal

The hydrogenation of 3-hydroxy propan al (HPA) to 1,3-propanediol (PD) over Ni/SiOi/AEO, catalyst powder was studied by Professor Hoffman s group at the Friedrich-Alexander University in Erlagen, Germany (Zhu et al., 1997). PD is a potentially attractive monomer for polymers like polypropylene terephthalate. They used a batch stirred autoclave. The experimental data were kindly provided by Professor Hoffman and consist of measurements of the concentration of HPA and PD (Chpa< Cpd) versus time at various operating temperatures and pressures.

Da die durch Anlagerung von Wasser an a, -ungesattigte Aldehyde entstehenden Hydroxy-aldehyde sehr leicht wieder Wasser abspalten, ist diese Addition meist nur schwierig durchzufiihren. Eine Ausnahme bilden die sehr reaktionsfahigen ,/ -ungesattigten Aldehyde z.B. Acrolein, das durch Kochen mit Wasser in 3-Hydroxy-propanal iibergefuhrt werden kann". 

The pyrrolidines were also prepared by using chemoenzymatic strategy for constructing the required azido-sugars (Scheme 1) Enzymatic aldol condensation of 2-azido-3-hydroxy propanal (35) and DHAP gave a diastereoisomeric mixture of 30 and 31, which... 

EPOXY-3-HYDROXY PROPANE (556-52-5) Combustible liquid (flash point 158T/ 70°C). Reacts violently with strong oxidizers. Contact with strong acids, caustics, chemically active metals (aluminum, copper, zinc, etc.), metal salts, trichloroethylene, especially in the presence of heat, can cause polymerization or exothermic decomposition. Incompatible with nitrates. Attacks some plastics, rubber, and coatings.
