Ⅰ Chemical formula and molecular weight
●Chemical formula:C12H27O4P
●Molecular weight:266.32
●CAS No.:126-73-8
Ⅱ Properties and uses
●Colourless,odorless transparent oily liquid,flash point 170℃,b.p. 289℃,refractive index 1.4226（20℃）,viscosity 3.5～12.2 c.p.（20℃) ..
●Soluble in ethanol,and other common organic solvent. Soluble in the water slightly,the solubility in this article is 7%(25℃),but would gradually hydrolyze with the increase of the temperature.
●Extensively used as a plasticizer for the nitryl cellulose,acetic cellulose,chlorination rubber,PVC；Can be used as the solvent of the coating,bond,printing ink,froth suppressor,static inhibitor；Also can be used as the extracting agent of the rare metal,but the boiling point is low,the volatilization loss is big,the application on plasticizer is limited.
