Claims
- 1. A method for the preparation of a hydroquinone dialkyl ether of the formula ##STR10## wherein R is a primary or secondary alkyl radical of from 1 to 4 carbon atoms, which comprises acidifying and heating, to a temperature of from about 60.degree. to 120.degree. C., a cyclohexene-(1)-dione-(3,6)-tetraalkyl diketal of the formula ##STR11##
- 2. A method for the preparation of a hydroquinone dialkyl ether of the formula ##STR12## wherein R is a primary or secondary alkyl radical of from 1 to 4 carbon atoms, which comprises acidifying and heating, to a temperature of from about 60.degree. to 120.degree. C., a cyclohexene-(1)-dione-(3,6)-tetraalkyl diketal of the formula ##STR13## which is dissolved in the alcohol ROH.
- 3. A method as defined in claim 1 or 2, wherein the heating is carried out for a time of from 10 to 60 minutes.
