✦ Synopsis

The kinetics of the thermal reaction between CF,OF and C,F, have been investigated between 20 and 75°C. It is a homogeneous chain reaction of moderate length where the main product is a mixture of the two isomers l-C,F,OCF, (68%) and 2-C3F,0CF3 (32%). Equimolecular amounts of CF,OOCF, and CsF,, are formed in much smaller quantities. Inert gases and the reaction products have no influence on the reaction, whereas only small amounts of oxygen change the course of reaction and larger amounts produce explosions.

The rate of reaction can be represented by eq. (I): (I) dp d' CF30FI -d1C3F6' -kICF,OFIIC,F,I + k*(CF,0F13/21C,F,I'/2 dt dt dt

The following mechanism explains the experimental results:
