Abstract:
1. A method for producing a compound of a general formula (2), the method comprising isomerizing at least a part of a compound of a general formula (1) in a material composition into the compound of the general formula (2) by heating the material composition containing at least the compound of the general formula (1) in the presence of a radical generating agent, wherein, in the general formulas (1) and (2), each of X and Y is a fluorine atom (F) or a hydrogen atom (H), and X and Y are not the same as each other; or each of X and Y is a chlorine atom (Cl) or a hydrogen atom (H), and X and Y are not the same as each other; and when in the general formulas (1) and (2), X is a hydrogen atom (H) and Y is a fluorine atom (F), the material composition is heated at a temperature higher than or equal to 150° C. and lower than or equal to 700° C. in isomerizing; or when in the general formulas (1) and (2), X is a fluorine atom (F) and Y is a hydrogen atom (H), the material composition is heated at a temperature higher than or equal to 150° C. and lower than or equal to 700° C. in isomerizing; or when in the general formulas (1) and (2), X is a hydrogen atom (H) and Y is a chlorine atom (Cl), the material composition is heated at a temperature higher than or equal to 150° C. and lower than or equal to 800° C. in isomerizing; or when in the general formulas (1) and (2), X is a chlorine atom (Cl) and Y is a hydrogen atom (H), the material composition is heated at a temperature higher than or equal to 150° C. and lower than or equal to 800° C. in isomerizing
