Method of producing a 2-((meth)allyloxymethyl)acrylic acid derivative, and 2-((meth)allyloxymethyl)acrylic acid alkali metal salt powder

A method of producing a 2-((meth)allyloxymethyl)acrylic acid derivative, the method comprising:

• reacting
• (i) a powder of a salt of a 2-((meth)allyloxymethyl)acrylic acid anion represented by the general formula (1) and an alkali metal cation (component A), and
• (ii) a halide represented by the general formula (4) (component B)
• with each other to produce a 2-((meth)allyloxymethyl)acrylic acid derivative
• wherein:
• in the general formula (1), R1 represents H or CH3, and M represents an alkali metal;
• in the general formula (4), R3, R4, and R7 each represent a hydrogen atom or an alkyl group, R5 and R6 each represent an alkyl group, an alkoxide group, or a siloxane group, “i” represents an integer of from 1 to 3, “j” represents an integer of 1 or more, “k” represents 0 or 1;
• and X represents a halogen group selected from the group consisting of a chlorine group, a bromine group, and an iodine group;
• and
• the 2-((meth)allyloxymethyl)acrylic acid derivative is:
• wherein R1 represents H or CH3, R3, R4, and R7 each represent a hydrogen atom or an alkyl group, R5 and R6 each represent an alkyl group, an alkoxide group, or a siloxane group, “i” represents an integer of from 1 to 3, “j” represents an integer of 1 or more, and “k” represents 0 or 1.
