Yield:1117-52-8 96%

Reaction Conditions:

with sodium hydroxide at 100; for 5 h;Large scale;Temperature;

Steps:

1; 2

Add 1500 g of ethyl farnesone, 150 g of 1% sodium hydroxide solution to the reactor, and stir.The reaction was performed at 100 ° C for 5h, and the temperature was lowered to room temperature. Phase,The organic phase is neutralized to neutrality using acetic acid.The solvent and light components were removed by distillation, and then rectified under reduced pressure to obtain 1181 g of farnesene acetone, with a content of 98%.The yield is 96%.
