Free Radical Addition

Under atmospheric pressure, a novel preparation of sodium diethylphosphinate was carried out by free-radical addition reaction of ethylene and sodium hypophosphite on gas-liquid interface. A self-design gas-liquid reactor was used to improve efficiency of the addition reaction , and made the product with purity of 99% obtained only in 6 hours，even no additional purification. The molecular structure of sodium diethylphosphinate was confirmed by FTIR, and31P NMR spectroscopic analysis.

A novel preparation of aluminum diethylphosphinate (AlPi) as a novel class of phosphorous based flame retardants was carried out with gas-liquid free-radical addition reaction under atmospheric pressure. The ethylene was bubbled into the reaction mixture with the addition of the initiator. With this novel method the gas-liquid contact surface and the initiator concentration in the gas-liquid interface were increased largely, and the yield of the final product was improved to at least 80%. The molecular structure of the samples was confirmed by FTIR,1H NMR and31P NMR spectroscopic analysis. Thermal stability of the final products was investigated in detail by TG-DTA.
