Reaction Steps
Oxalic acid in an amount of 10.78 g (0.120 mol) was dissolved in acetone, making a total of 100 g. The resultant solution was mixed with 100 g of 40% by weight solution of benzyltrimethylammonium hydroxide (0.261 mol) in methanol (produced by Tokyo Kasei Kogyo Co., Ltd.), and then 1500 g of acetone was added to the resultant mixture to form white precipitate. Subsequently, the precipitate was collected by means of suction filtration method, dispersed in 500 g of acetone and filtered to collect cake. The resultant cake was subjected to drying treatment under vacuum at 80° C. for 24 hours to form 33.9 g (0.0941 mol) of bis(benzyltrimethylammonium) oxalate at a yield of 78.4% based on the fed oxalic acid. The resultant bis(benzyltrimethylammonium) oxalate, in which a melting point was not recognized, was thermally decomposed in a stream of nitrogen at about 240° C.
