Methods of using waste in the processing of vegetable and fusel oils - a solution of glycerin, amyl and isoamyl alcohols in order to obtain ethers based on them, and thus ensure their integrated processing and creating waste-free technology of these processes are proposed. The method of utilization of glycerin solution, which is a waste in the process of hydrolysis of vegetable oil, by its esterification with acetic acid to obtain a valuable ester - triacetin, which is widely used in many sectors of the economy is proposed.
Natural clinoptilolite is used in a variety of technological processes, in particular as sorbents. In order to achieve high technological and techno-economic indicators of the processes in which zeolite is used, it is necessary to provide them with the highest possible sorption ability. This is achieved by activating natural zeolites by physical, physico-chemical and chemical methods. One of the promising methods of activating natural zeolites is their treatment in the field of ultrahigh-frequency electromagnetic radiation.
