The unexpected recovery of soybean oil phospholipids in the non‐polar eluents from a silicic acid column led to this investigation. Crude soybean oil dissolved in ethyl ether was mixed with silicic acid, filtered and the amount of phosphorus determined in the filtrate. Increasing time of contact with silicic acid, and pretreatment by heat or sonication decreased the amount of phosphorus in the filtrate. These findings indicate that phospholipids in crude soybean oil occur in a form that gives them a nonpolar character that can be changed. However, a certain portion of the phospholipids are not changed by the treatments described. These results are compared to phosphorus loss by degumming of soybean oil.
