aAccording to Lustig et al. (1993), the following furanones also appear during beer aging: dihydro-5,5-dimethyl-2(3H)-furanone, 5,5-dimethyl-2(5H)-furanone, dihydro-2(3H)-furanone, 3-methyl-2(5H)-furanone and 5-methyl-2(5H)-furanone According to Lustig et al. (1993), the...
1. The hydrogenation of 2-methyl-5-acetylfuran on a skeletal Ni-Al catalyst at 200–210° was investigated under hydrogen pressures of 10, 20, 40, 50, and 60 atm. 2. Increasing the hydrogen pressure from 10 to 50 atm suppresses the hydrogenolysis of the furan ring and the reduction of...
