Abstract
NEW MATERIAL:A compound of formulaI(R is H, alkyl, alkoxyl or halogen).
USE: A monomer for polyesters and particularly as a reaction intermediate polymerizable with a bifunctional carboxylic acid due to the two phenolic hydroxyl groups in both ends thereof.
PROCESS: A 4-hydroxybenzaldehyde of formula III or a nuclear substitution product thereof is stirred with pentaerythritol in an aromatic hydrocarbon, etc. as a solvent in the presence of an acidic substance, e.g. p-toluenesulfonic acid, under heating to give the compound of formulaI. The reaction temperature is 80W115°C (the boiling point of the used solvent).
