1997. The Bunsen Burner of the 21st Century. Dr. Ajay K. Bose. Field tests have shown that microwave-assisted experiments are rapid, safe and inexpensive. Reactants and selected solvents can absorb microwaves directly, while glass and ceramic vessels are almost transparent to them. The energy transfer to the reaction mixture can be started or stopped instantly by switching the over on and off. Most of the experiments outlined can be finished in less than an hour. Experiments include Testing Sweetners for Glucose Content, Aspirin Synthesis in 90 Seconds, Extraction of Caffeine from Tea, plus many more. 36 pages, soft cover,.
