NEOPENTYL GLYCOL DIMETHYLSULFATE 97 synthesis
- Product Name:NEOPENTYL GLYCOL DIMETHYLSULFATE 97
- CAS Number:53555-41-2
- Molecular formula:C7H16O6S2
- Molecular Weight:260.33
Yield:53555-41-2 100%
Reaction Conditions:
with triethylamine in ethyl acetate at 20; for 3 h;Cooling with ice;
Steps:
10
21.4 g (211.2 mmol) of triethylamine was added dropwise to a solution of 10.0 g (96 mmol) of neopentyl glycol and 24.2 g (211.2 mmol) of methanesulfonyl chloride in 90 mE of ethyl acetate under ice-cooling. Then, the temperature was raised to room temperature, followed by stirring for 3 hours. After 50 mE of water was added to the reaction system, the resultant product was stirred for 1 hour, and liquid-liquid separation was performed. Afier the organic layer was dried over magnesium sulfate, the solvent was distilled off under reduced pressure, whereby 25 g of (37-A) was obtained. (Yield of quant.)
