- CAS Number:28079-04-1
- Molecular formula:C14H26O2
- Molecular Weight:226.35
Yield:28079-04-1 95%
Reaction Conditions:
with pyridine at 5 - 25; for 2 h;Large scale;
Steps:
1.d ( Z/ Ε) -8-dodecene acetate
Synthesis of Z / E-8-dodecene enol (1.1kg, 6mol) and pyridine (31) were added to the reaction Kettle, cooled to 5-10 ° (after, add acetic anhydride (1.22kg, 12mol), naturally raise to room temperature 20-25 ° C to the end of the reaction; slowly add ice water to make the temperature <10 ° C, plus After stirring for 2 hours, extracted with n-hexane three times, with sulfuric acid to adjust the PH value of 1, and then Na2C03 washed to neutral, dry And the product was distilled under reduced pressure. (Z / Ε) -8-dodecene acetate 1.3kg, The yield of 95%, by GCMS test crossover ratio of 98:2.
