    Patent number: 5849955
    Abstract: A process is described for the synthesis of 2-hydroxy-4-alkyloxy benzophenone by the selective alkylation of 2,4-dihydroxy benzophenone with a dialkyl carbonate, in liquid phase, in the presence of suitable catalysts, at a temperature ranging between 120.degree. and 220.degree. C. and at a total pressure ranging from 2 to 60 ate.
    Type: Grant
    Filed: November 20, 1997

  • Procedure for alkylation of imides
    Patent number: 5780645
    Abstract: A process for the alkylation of imides wherein the imides are reacted with a dialkyl carbonate, in the liquid state, at a temperature of between 100.degree. C. and 250.degree. C. and at a pressure of between 0 and 60 atmospheres in the presence of a basic catalyst. The dialkyl carbonate reagents are not very toxic and are thermally stable and their use as alkylation agents makes it possible to produce waste products with a negligible saline content.
