Abstract: A process for the synthesis of tetrahydrolinalool from the residue of linalool rectification was studied. The residue contains dihydrolinalool and linalool. The synthetic process was investigated under different conditions of temperature，hydrogen pressure and the weight ratio of catalyst to reactant. Catalyst is the Lindlar catalyst，Raney Ni and 5%Pd/C. The main components of product were determined by GC/MS or 1H NMR spectra. With reaction conditions of temperature 90～92 ℃ and hydrogen pressure 2.0MPa for 4h，tetrahydrolinalool was obtained in 96.3% yield and 96.5% purity from the residue containing 38.3% dihydrolinalool and 59.2% linalool under the catalysis of 5%Pd/C.
