Abstract:
1. A method for producing a carbonate compound comprising: a first step of reacting a compound represented by the following Formula (1) with a compound represented by the following Formula (21) or a compound represented by the following Formula (22) to obtain a reaction mixture containing a carbonate compound, and a second step of bringing the reaction mixture containing a carbonate compound into contact with a strongly basic compound, wherein R 1 represents a monovalent organic group, and R 2 represents a divalent organic group, wherein the reaction mixture comprising a compound represented by the following Formula (41) or a compound represented by the following Formula (42), and in the second step, the reaction mixture is brought into contact with the strongly basic compound to decompose the compound represented by the following Formula (41) or the compound represented by the following formula (42), wherein x represents an integer of 0 to 2, and the method obtains a carbonate compound in which a total content of the compounds represented by Formula (41) and the compounds represented by Formula (42) is 5 ppm or less based on the total amount of the carbonate compound, and wherein the strongly basic compound is a salt of a base of which a conjugate acid has a pKa of 11 or higher and an alkali metal ion or an alkaline earth metal ion.
