ABSTRACT
Plasticizers are additives that increase the plasticity of polymers by increasing the flexibility of macromolecules. The selection of substances with a similar function is carried out in accordance with criteria that include requirements for non-toxicity, good miscibility, low migration ability, low volatility, etc. The plasticizers most used in plastics processing, for example polyvinyl chloride (PVC), are esters of carboxylic acids with linear or branched aliphatic alcohols of moderate chain length. In organic synthesis, research related to the application of ultrasound in the synthesis of esters is promising - the goals set are to reduce reaction time, increase yields, use safe raw materials, and reduce energy consumption. Its influence on the esterification process in the preparation of aliphatic and sucrose esters with short- and medium-chain fatty acids has not been sufficiently studied. The aim of the present study is to apply ultrasound in the esterification of stearic acid with fatty alcohols. The resulting esters are to be used as potential plasticizer additives in plastics, and the possibility of application in polyvinyl chloride has been investigated.
