Synthesis, Physicochemical Properties, and Thermo-Oxidative Stability of Triesters of 1,3,5-Adamantanetriol and 7-Ethyl-1,3,5-Adamantanetriol

Resumo

The synthesis of a series of triesters based on 1,3,5-adamantanetriol and 7-ethyl-1,3,5-adamantanetriol and C₄–C₆ aliphatic acids is executed, and their physicochemical and thermo-oxidative properties are studied. The properties of the obtained esters are compared to those of pentaerythritol esters. The synthesized esters have pour points below −40°C, the range of viscosities at 100°C varies from 4.361 to 9.912 mm²/s, and the values of the indices of thermo-oxidative stability are 221.6–240.3°C.
