A kind of synthesis technique of raspberry ketone

The invention discloses a kind of synthesis technique of raspberry ketone, comprising: 1) adopt θ ring Stainless Steel Helices fixed-bed reactor, formaldehyde and acetone are raw material, and NaOH is catalyzer, catalyze and synthesize butanone alcohol; 2) with butanone alcohol and phenol for raw material, adopt fluidized-bed reactor, ion exchange resin D218 is catalyzer, catalyzes and synthesizes raspberry ketone.The present invention is with acetone, formaldehyde for raw material, and NaOH is catalyst synthesis butanone alcohol, have with low cost, the reaction times is short, easy and simple to handle, side reaction is few, yield advantages of higher; Catalyze and synthesize raspberry ketone with storng-acid cation exchange resin D218, this process process equipment corrodibility is little, aftertreatment is simple, catalyzer repeat usage is high.This technique is a kind of production method of new and effective, environmental protection.
