실험 절차

One mol of phosphoric anhydride was added to three mols of octyl alcohol over a period of one hour at 60°-70° C. while stirring. They were allowed to react which each other at 70° C. for three hours and a mixture of mono and dioctyl phosphate was obtained. Separately, 0.5 mol of octyl dimethylamine and 200 ml of methanol were set inside an autoclave and after the interior gas was replaced by nitrogen, 0.5 molar equivalent of methyl chloride was introduced for a reaction at 60°-70° C. for three hours to obtain octyltrimethyl ammonium chloride. To this was gradually added 96 g of 28% sodium methylate-methanol solution (0.5 molar equivalent as sodium methylate) for salt exchange and the by-product sodium chloride was filtered away to obtain as filtrate a methanol solution of octyltrimethyl ammonium methoxide. To this methanol solution was added 0.5 mol of the aforementioned mixture of mono and dioctyl phosphate and after methanol was distilled away, it was diluted with water to obtain 50 wt% aqueous solution of octyltrimethyl ammonium octyl phosphate (Example No. 1).
