One-Pot Synthesis of P(O)-N Containing Compounds Using N-Chlorosuccinimide and Their Influence in Thermal Decomposition of PU Foams.

摘要: Synthesis of intermediate containing P(O)-Cl bonds is the key to converting P(O)-H P(O)-N. In this work we have performed chlorination reactions different H-phosphinates and H-phosphonates using N-chlorosuccinimide as an environmentally-benign chlorinating agent. The reaction showed high yield selectivity for transformation into analogues, resulting in easily separable succinimide by-product. Using a one-pot synthesis methodology, synthesized series P(O)-N derivatives whose was found be dependent on solvents starting materials. compounds were incorporated flexible polyurethane foam (FPUF) screened their influence thermal decomposition FPUFs thermogravimetric analysis (TGA) microscale combustion calorimeter (MCC). All solid influenced first-stage FPUFs, which resulted accelerated or temporary stabilization stage. However, liquid volatilize at earlier stage could active gas phase. addition, they also condensed phase via acid catalyzed FPUFs.
