実験手順

Tri-n-octyl-n-butylphosphonium bromide is prepared by slowing dripping tri-(n-octyl)phosphine (740 grams) into refluxing 1-bromobutane (500 grams) in a nitrogen atmosphere. Reflux is continued one hour after final addition then the solution is cooled with stirring for about 18 hours, followed by vacuum removal of excess 1-bromobutane at 60° C. This product, 1210 grams from two successive preparations, is added to 880 grams of sodium 3,5-dicarbomethoxybenzenesulfonate in 2500 ml. of water and stirred for at least one hour at 85° C. then the heat is removed and the oil-in-water mixture is stirred for about 18 hours. The oil layer is separated from the water, rinsed with 1000 ml. of water and dried at about 80° C. at a pressure less than 2 torr for 18 hours. This product, an oil, is tri-n-octyl-n-butylphosphonium 3,5-dicarbomethoxybenzenesulfonate with 4.2% phosphorus and 4.7% sulfur by analysis.
