Abstract
The linseed oil is achieved by using the supercritical CO2 extraction technique in this paper and the optimum conditions of orthogonal experiment are as follows:CO2 flow is 25L/h,extraction pressure 30MPa,extraction tempreture 45℃,extraction time 2 hours.Under these conditions,the experimental result shows that the average extraction rate is 36.7% and the extracted linseed oil is golden in colour and transparent.
