摘要：

In this study, the solubility parameter of vegetable oils and their interaction parameters values and dependence on temperature and gas flow rate was determined by inverse gas chromatography technique. Results show that there are three different areas in respect to flow rate that was not mentioned in previous studies. Slow, stable and fake marker areas and suggest that there is a relationship between fluids dynamic and solubility parameter values. Best flow rate was determined to be 30 ml/min. Despite the Flory Huggins theory prediction, there is no clear trend for Flory Huggins interaction parameter dependence on temperature. Also, the negative values for Flory Huggins interaction parameter were achieved by IGC method which could not be evaluated through the Flory Huggins theory. The solubility parameter will decrease by increasing temperature, and in high temperatures it will increase by increasing flow rate. The solubility parameter delta(2) determined to be 22.21, 22.70 and 21.38 (J/cm(3)) 0.5 at 25 degrees C for soybean oil, castor oil and rapeseed oil, respectively.
