(Microwave-type organic chemical reaction experiment apparatus) The green power of microwave opens the door to a new age of chemical synthesis.

“Green Motif Ib”, more compact and easier to use than the Green Motif I, is the organic chemical reaction experiment apparatus of the 21st century. 1 Using a single-mode wave-guide, uniform and efficient microwave irradiation of reactor possible. 2 Freely settable microwave power from 30W to a maximum of 300W Easily viewable digital meter allows user to set output at desired level 3 With a thermocouple for measuring reaction temperature and a digital temperature regulator, temperature can be regulated as one pleases from room temperature to 300 degrees C. Reaction time can also be set by timer. 4 Output monitor terminal fitted as standard, so microwave output status can be checked by recorder etc. 5 By switching out the reactor part, the apparatus can be adapted for not only test-tunbe use, but also for flask (reflux fitted) and continuous experiment. 6 6) With controls concentrated on the front panel, a user-friendly and symmetrical design has been pursued. AC 100V input, so no special facilities required. 7 Observation port either side of reaction chamber. Easy to read LEDs on the main unit allow reaction state to be checked. 8 Space under the reaction area provided for stirrer 9 Safe design to prevent microwave leakage. Automatic protection circuits to shut down microwave in the very unlikely event of a problem.

[fig 3] shows the warming curves for deionised water, dimethyl acetamide and ethylene glycol. Microwave power was set to 300W, and temperature limit was set at or near the respective boiling point. 10cc of solvent in a glass test-tube was used.

[fig. 4] shows the temperature control during temperature limit set for dimethyl acetamide. Microwave power was set at 300W, temperature limit was set at 150 degrees C, and 10cc of solvent in a glass test-tube was used. Temperature was recorded at 5 second intervals for 300 seconds. Solvent temperature was controlled within a range of 150 to 155 degrees C.
