【Abstract】 s The flame retarding plasticizer IPP was synthesized from POCl 3,phenol and propene etc The alkylation catalyst phenol sulfonic acid was selected,and the optimum alkylation reaction conditions were: W (phenol sulfonic acid)/ W (phenol)=1 5%,the reaction temperature was about 110 ℃,propene vent speed was 80 mL/min for 2 5 hours The esterification reaction conditions were: W (AlCl 3)/ W (POCl 3)=6 8%,the reaction temperature was about 120 ℃,and the reaction was terminated after 13 hours Finally the esterification catalyst AlCl 3 was removed with a physical and chemical combined process The local synthetic yield was about 83 6% The structure of the production was confirmed by FT IR,and element analyses更多还原
