The current article examines the regularities of obtaining starch esters with adipic acid and studies the rheological propertiesof the obtained starch adipates. In the course of the research, the author examines the kinetics of starch acylation with adipic acidin the presence of thionyl chloride and the kinetic regularities of the starch acylation process occurring in the topochemicalprocess using the Erofeev-Kolmogorov equation. The energy parameters are determined using the Eyring and Arrheniusequations based on the obtained values of the velocity constants. The study also provides the parameters of the transition complexformed during the acylation of starch with adipic acid. The formation of starch esters was confirmed via IR spectroscopy.
