摘要： SELECTIVE SEPARATION OF THE TRI-SUBSTITUTED HYDROCARBYL PHOSPHATES ONLY BY EXTRACTION FROM AN AQUEOUS SOLUTION OF WATER-SOLUBLE TRI-SUBSTITUTED HYDROCARBYL PHOSPHATES OF THE FORMULA (RO)2P(O)(OR'') WHEREIN R IS AN ALKYL OR ALKENYL GROUP HAVING 1 TO 3 CARBON ATOMS OR SAID GROUPS SUBSTITUTED BY CHLORINE AND R'' IS AN ALKYL OR ALKENYL GROUP HAVING 1 TO 4 CARBON ATOMS OR SAID GROUPS SUBSITUTED BY CHLORINE. THE COMPOUNDS ARE USEFUL AS ADDITIVES FOR GASOLINE, PLASTICIZERS FOR THERMOPLASTIC RESINS AND FLAME RETARDING AGENTS FOR RIGID POLYURETHANE FOAM, POLYESTER RESIN, ETC.

摘要： PREPARATION OF TRI-SUBSTITUTED HYDROCARBYL PHOSPHATES, BY REACTING DIHYDROCARBYLCHLOROPHOSPHATES WITH ALCOHOLS IN THE PRESENCE OF CAUSTIC ALKALIS, SUCH AS CAUSTIC SODA AND CAUSTIC POTASH, ETC., WHEREBY THE HYDROEN CHLORIDE FORMED SIMULTANEOUSLY IS NEUTRALIZED QUICKLY WITH THE CAUSTIC ALKALI. ACCORDING TO THIS PROCESS, IT IS POSSIBLE NOT ONLY TO PREVENT THE DECOMPOSITION OF DIHYDROCARBYLCHLOROPHOSPHATES BUT ALSO TO SUPPRESS THE SIDE REACTION REPRESENTED BY THE EQUATION:

(RO)3PO+HCL-->(RO)2P(O)OH+RIL

WHEREIN R IS AN ALKYL GROUP. THE COMPOUNDS PRODUCED BY THE INVENTION ARE USEFUL AS ADDITIVES FOR GASOLINE, PLASTICIZERS FOR THERMOPLASTIC RESINS AND FLAME RETARDING AGENTS FOR RIGID POLYURETHANE FOAM, POLYESTER RESIN, ETC.
