Pure pentanal is irradiated with a frequency tripled Nd-YAG laser in the intensity interval 0.1-1 MW. cm−2. Alpha-dione and α-ketol are formed selectively with quantum yields of 5.5 and 38%, respectively. As only the S1 state of the pentanal is excited, the results obtained are explicable as a ...detailed
Lipid oxidation can adversely alter sensory and nutritional attributes of fats preserved in food powders. The aim of this study was to compare the extent of lipid oxidation in spray dried conventional emulsions and nanoemulsions. Powders containing lactose or lactose/sucrose (7:3) (57.9 g/100 g)...detailed
Dodecamolydbophosphoric acid (HPMo) immobilized on USY zeolite was used as a catalyst for the acetalization of glycerol with pentanal at 70 °C. Catalysts were prepared with different amounts of heteropolyacid, and the most active sample was the [email protected] catalyst (1.1 wt.%). The product...detailed
