Abstract: Phase balance of hexane-ethanol-water system and balance relation between water content in flaxseed and ethanol concentration for extraction were studied. Results showed that mutual solubility of hexane-ethanol-water system increases along with augmentation of temperature and ethanol concentration,which shows balance relation between water content of flaxseed and ethanol concentration of three fractions solvent system in the course of extraction. The corresponding balance relations are as follows:95 % ethanol concentration in solvents to 7 %~9 % water content in flaxseed,90% ethanol concentration in solvents to 9 %~11 % water content in flaxseed and 85 % ethanol concentration in solvents to 10 %~12 % water content in flaxseed.

Key words: hexane, ethanol, water, phase balance
