Glycerol oxidationGlyceric acidVicinal hydroxyl groupSelective oxidation of glycerol provides a feasible route towards the sustainable synthesis of high value-added chemicals.Herein,the hydroxyapatite(HAP)supported palladium(Pd)species were fabricated by impregnation and subsequent calcination.The as-obtained ...
Polyether polyol Soft foam polyether Hydroxyl value 56 MW3000 F5631 is a polyether polyol based on glycerol. The product has no BHT, and is used for mattress, cushion, furniture and other block soft foam, suitable for low, medium and high density polyurethane fo...
The cells from 400 ml of the culture were harvested by centrifugation. The pellet was completely re-suspended in ice-cold buffer D (100 mM Tris-HCl, 300 mM KCl, 50 mM arginine, 1% glycerol pH 8.0), and extra 4 mg mL−1 of lysozyme was later added to the suspension....

The resins could be cured easily with toluene diisocyanate and glycerol. The DTA-TG data show that the cured samples start to decompose exothermically at relatively low temperatures, in the range around 160掳C. The resins ignite immediately on coming in contact with pure nitric acid, indicating ...
In approach A, flavone is dissolved in a pyridine solvent of ethylene glycol or glycerol, iodine is used as a dehydrogenation agent, and flavone is produced by heating and dehydrogenation. In approach B, as aluminum salts having valence value 3 are easy to form a complex with flavanone and ...
