Kinetics of the reaction between boron trifluoride methanol complex and sodium methoxide to produce enriched 10 B methylborate
2016
The relation of boron trifluoride concentration with conductivity in boron trifluoride methanol solution (BF3-CH3OH)was power exponent fitted in low concentration range. The kinetics of the reaction between boron trifluoride methanol complex and sodium methoxide to produce enriched 10B methylborate was proposed based on a detailed mechanism study, and was verified by acid-base titration method and conductivity method. It was found that this reaction is first order reaction and the rate constant is 0.022 min−1 at 338 K(65 °C), the activity energy is 65 kJ/mol. In addition, it was found that the conductivity method is more feasible to measure the kinetic curve than acid-base titration method.
