YieldReaction ConditionsOperation in experiment
4.8 g With phosphorus pentoxide; sulfuric acid; at 120℃; for 1.0h; Example 2 12.6 g (0.05 mol) of potassium salt of methanedisulfonic acid, 2.5 g (0.025 mol) of concentrated sulfuric acid, and 7.2 g (0.05 mol) of phosphorus pentoxide were placed in a four-necked flask equipped with a stirrer, a condenser, a thermometer, and a dropping funnel. 1.6 g (0.05 mol) of 92percent paraformaldehyde was added to the mixture while stirring at room temperature. After completion of the addition, the mixture was heated to 120° C. and stirred for one hour. The mixture was then cooled to room temperature and 200 g of methylene chloride was added thereto. After stirring for one hour, insoluble matter was filtered off. The filtrate was concentrated to obtain crystals, and the resulting crystals were dried at 40° C. and 10 mmHg for 6 hours, giving 4.8 g of light brown crystals of methylene methanedisulfonate represented by formula (3) wherein R1 and R2 are hydrogen atoms, and n is 1. The yield of the resulting methylene methanedisulfonate was 51 mol percent relative to potassium salt of methanedisulfonic acid. [0060] In the same manner as Example 1, the 1H-NMR analysis results confirmed that the resulting light brown crystals were methylene methanedisulfonate.
