Biodiesel is a biofuel made from vegetable oil through an esterification-transesterification process. The process of making biodiesel carried out by conventional heating methods and microwave heating. reaction was according to the specified variables, with concentration 0.1% volume methanol variable power 135, 225 315 watts time variations 5, 3 1 minute, as well at 60°C for hour. best result on...

Sucrose hydrolysis reaction, catalysed by invertase under microwave irradiation was carried out in aqueous, isopropanol + water and polyethylene glycol + water system. The effect of conventional and microwave heating on the rate of hydrolysis was studied under a range of physical exposure conditions. The catalytic activity of invertase in aqueous and organic solvents were measured at different ...

We have previously reported a new synthesis of amides from esters and amines under microwave irradiation, offering much higher yields than those achieved with conventional heating [1]. We have now extended these studies to the ring closure of neat iminoesters I2, I3 and I4-I6 to give five- and six-membered ring lactams L5, L6 and larger lactams L7-L9 (where I means imine and L means lactam), re...
