Reaction Conditions:
with trichlorophosphate in chloroform at 90; for 9 h;Temperature;Solvent;Concentration;
Steps:
8 The method for synthesizing 2-naphthalenesulfonyl chloride with phosphorus oxychloride in the invention comprises the following steps:
1) 346 g (1.5 mol) of sodium 2-naphthalenesulfonate and 770 g (5 mol) of phosphorus oxytrichloride were successively added to 2.25 mol of chloroform to obtain a reaction solution a;2) The reaction liquid a obtained in the step 1) is reacted at a temperature of 90 ° C for 9 hours to obtain a mixed liquid b;3) the step 2) obtained by the mixture b continued to steam out the excess of phosphorus oxychloride and chloroform, followed by washing, filtration, vacuum distillation, in 2 - naphthalene sulfonyl chloride.It was calculated that the product yield of the 2-naphthalenesulfonyl chloride was 95.8%.
