Diethyl Phthalate
CAS Number: 84-66-2
Molecular Formula: C12H14O4 or C6H4-1,2-(CO2C2H5)2
Molecular Weight: 222.24
Diethyl Phthalate
Specifications of Diethyl Phthalate USP NF Grade:
C12H14O4 --- 222.24
1,2-Benzenedicarboxylic acid, diethyl ester;
Diethyl phthalate --- CAS 84-66-2
DEFINITION
Diethyl Phthalate contains NLT 98.0% and NMT 102.0% of diethyl phthalate (C12H14O4), calculated on the anhydrous basis. [Caution— Avoid contact. ]
IDENTIFICATION
A. Infrared Absorption: On undried specimen
ASSAY
Procedure:
Sample: 1.5 g
Titrimetric system
Mode: Residual titration
Titrant: 0.5 N alcoholic potassium hydroxide
Back-titrant: 0.5 N hydrochloric acid
Endpoint detection: Visual
Analysis: Transfer the Sample to a flask, add 50.0 mL of the Titrant, and boil with a reflux condenser on a water bath for 1 h. Add 20 mL of water, then add phenolphthalein. Titrate the excess potassium hydroxide with the Back-titrant. Perform a blank determination. Each mL of 0.5 N potassium hydroxide is equivalent to 55.56 mg of diethyl phthalate (C12H14O4 ).
Acceptance criteria: 98.0%–102.0% on the anhydrous basis.
Residue on Ignition:
Sample: 10 g
Analysis: Gently heat the Sample until the liquid has evaporated, and ignite the residue to constant weight.
Acceptance criteria: NMT 0.02%
Specific Gravity: 1.118–1.122 at 20C
Refractive Index: 1.500–1.505 at 20C
Acidity:
Sample: 20.0 g
Analysis: Mix the Sample with 50 mL of alcohol that previously has been neutralized to a phenolphthalein endpoint, and titrate with 0.1 N sodium hydroxide to a phenolphthalein endpoint.
Acceptance criteria: NMT 0.50 mL is required for neutralization.
Water Determination, Method I: NMT 0.2%
