Phase diagram of a system of adipic, glutaric, and sebacic acids
Adipic acid–glutaric acid, glutaric acid–sebacic acid, and adipic acid–sebacic acid binary systems are studied, along with an adipic acid–glutaric acid–sebacic acid ternary system. It is shown all of these systems are eutectic. Phase equilibria for the diagram elements of the binary systems and the ternary system are described. It is concluded that the above low-melting compounds can be recommended for use as working bodies in heat accumulators, and for preparing electrolytes used in the thin-layer anodic oxidation of aluminum alloys.
