Kinetic studies of the thermal decomposition of 2-chloroethylphosphonic Acid in aqueous solution.
The decomposition of 2-chloroethylphosphonic acid in aqueous solution has been studied at pH values from 6 to 9 and at temperatures in the 30 to 55 C range. The rate of decomposition is estimated from the rate of formation of ethylene. The rate is proportional to the concentration of the phosphonate dianion and is independent of the hydroxyl ion concentration. The rate constant at 40 C is 1.9 x...
متن کاملEffect of water vapor pressure on the thermal decomposition of 2-chloroethylphosphonic Acid.
Decomposition of 2-chloroethylphosphonic acid (Ethephon) was studied in dried films at various water vapor pressures (0.6 to 86.9 millimeters Hg, 3.2 to 93.9% relative humidity) and temperatures (20, 30, 40, and 50 C) at pH 6.3 and 7.0. The rate of decomposition could be determined equally well by [(14)C]Ethephon or ethylene measurements. The rate increases at increasing water vapor pressures a...
