Reed (typha) mill was converted to liquid products by using organic solvents (methanol, ethanol and acetone) with catalysts (% 10 NaOH and ZnCl2) and without catalyst in an autoclave at temperatures of 533, 553, and 573 K. The liquid products were extracted by liquid-liquid extractio[DSA 1]n (benzene and diethyl ether). The yields from supercritical methanol, ethanol and acetone conversions were 362, 24.5, and 55.1 %, respectively, at 573 K. In the catalytic runs with methanol and ethanol extracts were 463 and 35.5% (for NaOH catalyst) and 51.8 and 38.5% (for ZnCl2 catalyst) respectively, at 573 K. The yields from supercritical methanol were increased from 38.2 to 52.4% as the temperature was increased from 533 to 573 K in the catalytic run.
