Method for producing carbonate derivative

A method for producing a carbonate derivative,

• the method consisting of an optional step of stirring a liquid composition comprising a halogenated methane and a hydroxy group-containing compound without irradiating a high energy light, and a step of irradiating the high energy light to the liquid composition in the presence of oxygen to produce the carbonate derivative, and optionally repeating the optional step of stirring and the step of irradiating,
• wherein the liquid composition does not comprise a base,
• wherein a molar ratio of a total usage amount of the hydroxy group-containing compound to 1 mole of the halogenated methane is 0.1 or more,
• wherein the hydroxy group-containing compound is represented by the following formula (i) and the carbonate derivative is a linear carbonate derivative represented by the following formula (I), or
• the hydroxy group-containing compound is represented by the following formula (ii) and the carbonate derivative is a carbonate derivative comprising a unit represented by the following formula (II-1) or a cyclic carbonate derivative represented by the following formula (II-2):
• R1—OH (i)
• HO—R2—OH (ii)
• R1—O—C(═O)—O—R1 (I)
• [—O—R2—O—C(═O)—] (II-1)
• wherein
• R1 is a monovalent C1-200 organic group optionally comprising a hetero atom,
• R2 is a divalent C1-200 organic group optionally comprising a hetero atom.
