HYDROXY-AROMATIC COMPOUND, PROCESS FOR ITS PREPARATION, AND USE AS ANTIOXIDANT

摘要

The invention relates to a process for the preparation of a hydroxy- aromatic compound. The process comprises the steps of bringing a starting compound according to formula (I) together with an alkanol hemiacetal according to formula (II) to form a reaction mixture. The reaction mixture is then brought to conditions whereby the hydroxy-aromatic compound is formed. Formula (I) is: wherein R<SUB>1</SUB> and R<SUB>2</SUB> each individually are a C<SUB>1</SUB> - C<SUB>20</SUB> alkyl group. Formula (II) is: wherein R<SUB>6</SUB> is a C<SUB>1</SUB>-C<SUB>12</SUB> alkyl group, aryl group, aralkyl group or cycloalkyl group and wherein R<SUB>12</SUB> is H, a C<SUB>1</SUB>-C<SUB>12</SUB> alkyl group, aryl group, aralkyl group or cycloalkyl group.
