The process condition of subcritical butane extraction of cottonseed oil was studied, and the quality of the product was detected and analyzed. The Box-Behnken response surface design was em-ployed to optimize the process condition on the basis of single factor experiment. The optimal process pa-rameters of subcritical butane extraction of cottonseed oil were obtained as follows:extraction temperature 47℃,extraction times 4, extraction time 36 min, particle size 60 meshes. Under these conditions,the ex-traction rate was 93 . 1%. The results indicated that the quality of the cottonseed oil extracted by subcriti-cal butane was better,resulting in a reduction of refining cost and better economic benefit.
