摘要：
The present invention provides a method for producing a methylene disulfonate compound including reacting, in the presence of an acid and a dehydrating agent, a formaldehyde compound with at least one salt of alkanedisulfonic acid selected from the group consisting of alkali metal salts of alkanedisulfonic acid and alkaline earth metal salts of alkanedisulfonic acid each represented by a specific formula. According to the method of the present invention, a methylene disulfonate compound can be obtained in a simple manner at low cost.
