PHOSPHATE ESTER FLAME RETARDANTS FROM RESORCINOL-KETONE REACTION PRODUCTS

摘要

invention Playa van Dijk and spiro compounds with only oxychloride , mono -phenyl- dichloro -diphenyl phosphate or by reacting the chloro compound Plastic bangye phosphate compound-based phosphate esters and spiro Dijk only starts to be produced . Van Dijk and spiro only the plastisol compounds can be synthesized by the reaction of resorcinol and the aliphatic acetone . The phosphate esters may be used as a flame retardant .
