Decomposition method of fluorine atom-containing polymer and decomposition device of fluorine atom-containing polymer

摘要

PROBLEM TO BE SOLVED: To provide a new decomposition method of a fluorine atom-containing polymer. SOLUTION: In the presence of at least one basic compound selected from the group consisting of alkali metal hydroxides and alkaline earth metal hydroxides, a fluorine atom-containing polymer to be decomposed is subcritical at 200 ° C. or higher. A method for decomposing a fluorine atom-containing polymer, which comprises a step of contacting with water, may be used. According to this method, it is considered that hydrogen fluoride (HF) is extracted from the polymer by the basic compound to cause decomposition of the polymer. After decomposition, the polymer is considered to be an elemental carbon with a double bond. [Selection diagram] None
