Abstract
The present invention provides a process for producing phenol-dicarbonyl condensates high in fluorescence by reacting a phenolic compound with a 1,2-dicarbonyl compound in the presence of a catalyst selected from one or more carboxylic acid(s) or one or more carboxylic acid precursor(s). The present invention further provides phenol-dicarbonyl condensates, epoxy resins, epoxy resin systems and laminates prepared using these phenol-dicarbonyl condensates.
Claims26
A process for producing phenol-dicarbonyl condensates high in fluorescence, said process comprising reacting one or more phenolic compounds with one or more 1,2-dicarbonyl compounds in the presence of one or more carboxylic acid(s) catalysts or one or more carboxylic acid precursor(s) catalysts comprising maleic acid, fumaric acid, dihydroxyfumaric acid, acetylenedicarboxylic acid, 2,6-dihydroxybenzoic acid, salicylic acid, maleic anhydride, citraconic anhydride or chloromaleic anhydride.
A phenol-dicarbonyl condensate comprising the reaction product of one or more phenolic compound with one or more 1,2-dicarbonyl compounds in the presence of one or more carboxylic acid(s) or one or more carboxylic acid precursor(s) comprising maleic acid, fumaric acid, dihydroxyfumaric acid, acetylenedicarboxylic acid, 2,6-dihydroxybenzoic acid, salicylic acid, maleic anhydride, citraconic anhydride or chloromaleic anhydride.
