Abstract

ON PREPARE DES ACIDES OU DES ESTERS CETONIQUES, OU LEURS PRECURSEURS, PAR EXEMPLE LES DIESTERS DE L'ACIDE ACETONE DICARBOXYLIQUE, EN FAISANT REAGIR UN ACIDE A-HYDROXYLE, PAR EXEMPLE L'ACIDE CITRIQUE, OU UN DERIVE DE CET ACIDE, AVEC UN ACIDE MINERAL ANHYDRE OU UN ANHYDRIDE D'ACIDE CARBOXYLIQUE EN PRESENCE D'UN SOLVANT ORGANIQUE INERTE ET NON MISCIBLE A L'EAU. IL EST POSSIBLE DE DIMINUER LES DIFFICULTES DE FABRICATION QUAND ON PREPARE LES ACIDES OU ESTERS CETONIQUES DANS UN MILIEU REACTIONNEL CONTENANT UN TEL SOLVANT ORGANIQUE. LES ESTERS DE L'ACIDE ACETONE DICARBOXYLIQUE SONT UTILES COMME CATALYSEURS POUR LA POLYMERISATION DU CHLOROPRENE, ET ON PEUT EGALEMENT LES FAIRE REAGIR AVEC DES AMINES PRIMAIRES ET UNE HALOACETONE POUR FORMER DES ESTERS DE PYRROLE SUBSTITUES QUI SONT DES PRODUITS PHARMACEUTIQUES.
