  • PROCESS FOR PRODUCING 3,4' DIACETOXYBENZOPHENONE
    Publication number: 20100217046
    Abstract: A process for producing 3,4?diacetoxybenzophenone by first synthesizing 3,4?dihydroxybenzophenone by reacting meta-hydroxybenzoic acid and phenol in the presence of a Lewis acid, and a protonic acid followed by reacting the 3,4?dihydroxybenzophenone with an acetylating agent in the presence of an inorganic acid and activated carbon.
    Type: Application
    Filed: February 26, 2009
    Publication date: August 26, 2010
    Applicant: E.I. DU PONT DE NEMOURS AND COMPANY
    Inventors: Kiu-Seung LEE, Michael Francis VINCENT
  • PROCESS FOR PRODUCING 3,4' DIHYDROXYBENZOPHENONE
    Publication number: 20100217047
    Abstract: A process for synthesizing 3,4?dihydroxybenzophenone by reacting meta-hydroxybenzoic acid and phenol in the presence of a Lewis acid, and a protonic acid. Upon completion of the reaction the Lewis and protonic acids are removed and then the reaction product of 3,4?dihydroxybenzophenone is contacted with water (at temperature not greater than 10° C.) and ammonium hydroxide followed by filtration.
