Process for preparing condensation product of hydroxy-substituted aromatic compounds and glyoxylic reactants |
摘要 |
The present invention is directed to a process for preparing a condensation product of a glyoxylic reactant and a hydrocarbyl-substituted aromatic compound having at least one hydroxy functionality, which includes (a) providing the glyoxylic reactant in the form of a compound represented by the formula <CHEM> or its reactive equivalent, wherein R<1> and R<3> independently are hydrogen or hydrocarbyl group of 1 to about 4 carbon atoms; and R<2> and R<4> independently are hydrocarbyl groups of 1 to about 4 carbon atoms; (b) mixing the aromatic compound with the glyoxylic reactant; and (c) heating the mixture to a temperature of about 50 DEG C to about 200 DEG C in the presence of an acid catalyst for a sufficient time to form the condensation product. |
