Characteristics and synthetic raw materials of aliphatic dibasic acid ester plasticizers

Aliphatic dibasic acid ester plasticizers mainly include esters of adipic acid, azelaic acid, and sebacic acid. They are formed by direct esterification of these dibasic acids and monohydric alcohols. For example, dioctyl sebacate is synthesized by direct esterification of sebacic acid and 2-ethylhexanol. Aliphatic dibasic acid ester plasticizers are characterized by excellent low-temperature properties. When…
