概要 Owing to their high chemical and thermal stability, fluoropolymers are used in industrial equipment to impact corrosion resistance. Wider use of the fluoropolymers will require the establishment of waste treatment. These polymers can be incinerated. However, incineration requires high temperatures to break the strong C−F bonds, and the hydrogen fluoride gas that forms can damage the firebrick of an incinerator. Herein we report on the decomposition of a typical fluoropolymer, poly(chlorotrifluoroethylene) (PCTFE, −(CF2CFCl)n−), by use of subcritical and supercritical water. An effective methodology for the decomposition of PCTFE to F– ions and details of the products (including gaseous minor species) are presented.
