Dimethyl phthalate synthesis
- Product Name:Dimethyl phthalate
- CAS Number:131-11-3
- Molecular formula:C10H10O4
- Molecular Weight:194.18
Yield:131-11-3 96%
Reaction Conditions:
with sulfuric acid for 24 h;Reflux;
Steps:
Synthesis of phthalic acid ester 3
Phthalic acid (2, 6.00 g, 36.2 mol) was dissolved in methanol (130 mL). After thatconc. sulfuric acid (6.80 mL) was slowly added dropwise. The reaction mixture wasstirred under reflux for 24 h. After cooling down to room temperature the solution wasconcentrated and added to a mixture of 200 mL dichloromethane/water (1:1). Theaqueous phase was extracted three times with dichloromethane. The combinedorganic layers were dried over magnesium sulfate and the solvent was removedunder reduced pressure. A yellow oil was obtained
