Synthesis method for 9-decenol

The invention discloses a synthesis method for 9-decenol. The synthesis method includes the following steps that 1,10-decanediol, higher fatty acid and a catalyst are stirred, mixed and heated to 340-360 DEG C, and a mixed matrix is obtained; 1,10-decanediol is continuously fed into the mixed matrix with the temperature maintained at 340-360 DEG C in a dropwise adding mode, and continuous discharging is achieved in a rectification mode; an obtained discharged material is subjected to normal-pressure rectification, and 99+/-0.5 DEG C fraction is collected; remaining materials are subjected to vacuum rectification, 110+/-0.5 DEG C/30 mm Hg fraction is collected, and 9-decenol is obtained; 1,10-decanediol is mixed into kettle bottom liquid obtained after vacuum rectification, an obtained mixture replaces 1,10-decanediol for continuous feeding, and a circular reaction can be continuously performed.
