Abstract
The results of studied on the use of ultrasound in catalyst synthesis and processing are summarised. It is demonstrated that exposure to ultrasound can regulate the textural and structural characteristics of catalysts by varying exposure time and the amplitude of ultrasonic radiation. Optimisation of the conditions of ultrasonic treatment of the catalysts is determined to provide improvement of their physicochemical properties. This allows achieving higher reagents conversion and selectivity of the formation of target products in various chemical reactions. Examples of ultrasound application from the viewpoint of following the green chemistry principles are considered. It is shown that ultrasound application in organic synthesis promotes improvement of chemical process characteristics and reduces reaction time.
