Methyl decanoate synthesis
- Product Name:Methyl decanoate
- CAS Number:110-42-9
- Molecular formula:C11H22O2
- Molecular Weight:186.29
Yield:110-42-9 97%
Reaction Conditions:
with sulfuric acid;acetonitrile at 80 - 85; for 16 - 18 h;
Steps:
Procedure for ester (Table 2, entry 1-12 ):
General procedure: To a well-stirred mixture of acid (80 mmol), alcohol (90 mmol), acetonitrile (162 mmol) and sulfuric acid (98%, 94 mmol, 5 mL) was added at room temperature. Slowly heated to 80-85 °C and maintained between 80-85°C for16-18 h. The reaction mixture was cooled and added to 20% sodium carbonate solution (100mL). The reaction mass was extracted in CH2Cl2 (50 mL × 2). The combined organic layer was washed with water (100 mL), dried over sodium sufate, and concentrated under reduced pressure to obtain corresponding ester (97-99%) as the only product. Most example gave NMR pure product. Where minor impurities are formed, the product was purified over silica gel using ethyl acetate: petroleum ether (1:9).
