摘要:
In the production of aromatic sulfones by the condensation reaction of an arylsulfonyl chloride with an arene, practically quantitative yields of the aromatic sulfone are obtained without the usual purification and work-up problems by conducting the condensation reaction in the presence of relatively large amounts (based on the molar concentration of the arylsulfonyl chloride) of the particular arylsulfonic acid which corresponds to such arylsulfonyl chloride, but substantially in the absence of any metal salts. Using in conjunction with this improved method for producing the aromatic sulfone a new and unique technique for producing the arylsulfonyl chloride, which technique is based on chlorinating the aromatic sulfonic acid with chlorosulfonic acid in the presence of certain organic solvents so that equilibrium of such chlorination is displaced toward formation of the resultant arylsulfonyl chloride, an extremely efficient process has been developed for the production of aromatic sulfones. This process is described in detail in connection with the production of bis-(p-chlorophenyl) sulfone, which is a commercially important monomer in the manufacture of many thermoplastic polysulfone polymers.
