Pitch fluoride is a new fluorine carbon compound which has superior water repellency with a contact angle of more than 145 degrees. In this study, adopting solid pitch fluoride as a starting material, liquid and solid glassy types of pitch fluoride were synthesized by direct fluorination at final temperatures ranging from 200°C to 400°C. The reaction conditions giving the maximum yield of liquid fluoride were investigated. Synthesized liquid pitch fluoride was distilled under a reduced pressure and fractionated at different temperatures. Measurements of average molecular weight and <SUP>19</SUP>F-NMR and elementary analysis were conducted for the fractionated liquid fluoride as well as the synthesized liquid and glassy products, together with the measurements of surface tension, viscosity, refractive index and specific gravity.
