| titleOfInvention | Process for the preparation of mono-ethers of hydroquinones |
| abstract | Mono-ethers of hydroquinones of formula (I) <CHEM> wherein R represents alkyl, alkoxy-alkyl, cycloalkyl, aryl-alkyl, or cycloalkyl-alkyl, and R<1> is hydrogen or alkyl, cycloalkyl, aryl-alkyl, or cycloalkyl-alkyl, are prepared by contacting the corresponding hydroquinones with the corresponding alcohols ROH, in the presence of a catalytic mixture consisting of a) a strong acid b) a halogen or a hydrohalic acid selected from HBr, HI, I2, and Br2, and c) H2O2 in a molar amount lower than that of the starting hydroquinone. o |
