Merck PG Propylen Glycol - 1,2 Propanediol, EXP, Ph EUR,BP,USP Farma Kalite. The equilibrium solubility at five temperatures from (293.15 to 313.15) K, apparent dissolution, mixing and solvation thermodynamics, and apparent specific volume at saturation of acetaminophen (ACP) in {ethanol (EtOH) (1) + propylene glycol (PG) (2) + water (3)} mixtures is reported. Propylene glycol is metabolized into lactic acid, which occurs naturally as muscles are exercised, while ethylene glycol is metabolized into oxalic acid, which is toxic. Under the conditions described, the approximate retention time for propylene glycol is 5.7 min, and 8.2, 9.0, and 10.2 min for the three isomers of dipropylene glycol, respectively. CAS 25265-71-8, pH 6 - 7 (100 g/l, H₂O, 20 °C). Ethylene Glycol 107-21-1 Hazard Summary Ethylene glycol has many uses, including as antifreeze in cooling and heating systems, in hydraulic brake fluids, and as a solvent. Propylene glycol is commonly used as an excipient in a variety of drugs and it is also authoris ed in food products and cosmetics. In this study, different acidic (V2O5, ZrO2, and TiO2) and basic (CaO and MgO) oxide-supported copper–zinc bimetallic catalysts were prepared by a deposition–precipitation method, and they were evaluated for the vapor-phase hydrogenolysis of glycerol to propylene glycol at 0.1 MPa and at 220 °C. propylene glycol by weight have no flash point as obtained by standard test methods.
