METHOD OF PRODUCING PLASTICIZER AND REDUCING ENERGY CONSUMPTION

Systems and methods for producing a non-phthalate based plasticizer. The systems and methods involve dissolving a carboxylic acid and/or anhydride thereof in an alcohol at a temperature below the melting point of the carboxylic anhydride. An advantage of the method is reduced energy consumption compared to conventional methods that require melting the carboxylic anhydride. Furthermore, the methodenables the production of non- phthalate based plasticizer in an existing phthalate based plasticizer production facility with minimal modification, thereby reducing capital expenditure. 用于生产非邻苯二甲酸酯基增塑剂的系统和方法。所述系统和方法涉及将羧酸和/或其酸酐在低于羧酸酐的熔点的温度下溶解于醇中。与需要熔化羧酸酐的常规方法相比，所述方法的优点是降低能耗。此外，所述方法使得能够在具有最小改进的现有邻苯二甲酸酯基增塑剂生产设施中生产非邻苯二甲酸酯基增塑剂，从而降低资本支出。
