Ⅰ Chemical formula and molecular weight
●Chemical formula:C33H54O6
●Molecular weight:546.79
●CAS No.:3319-31-1
Ⅱ Properties and uses
●Colourless,transparent oily liquid,b.p.283℃（3mmHg）,viscosity 100～300 c.p.（20℃）,refractive index 1.4485（25℃）.
●Used as a heat-endurant and long-lasting plasticizer for polyvinyl chloride,usually for preparing Grade 105℃ electrical cable and other heat-resisting plastic products.
●It possesses both advantages being used as plasticizer for polyesters and for general purposes. Except producing oilresisting ones,also used in preparing any long-lasting products.
