ULTRASOUND ASSISTED PROCESS FOR SYNTHESIS OF CHALCONE.

摘要

The present invention discloses a energy efficient process for the synthesis of chalcone derivatives by using ultrasound energy. Chalcone was successfully synthesized at room temperature by conventional (NUS) and sonochemical method (US). Detailed structural characterizations demonstrate that the US synthesized chalcones, which was synthesized in 10 min, are more stable and lower in particle size than the NUS synthesized chalcone. Sonochemical synthesis (US) method has saved substantial energy (more than 88%) for the synthesis of chalcone. Thus, the sonochemical synthesis technique is fast, simple, convenient, time saving, economical, and environmentally benign method of chalcone synthesis. This method promises a future iargescale synthesis for many organic intermediates. In view of the above, it can be seen that several advantages of the invention are achieved and other advantageous results are attained. As various changes could be made in the above methods and compositions without departing from the scope of invention, it is intended that all matter contained in the above description shall be interpreted as illustrative and not in limiting sense.
