    • Cyclohexanedione-(1,4)-tetramethyl diketal of the formula ##STR1## is obtained by catalytic hydrogenation of p-benzoquinone tetramethyl diketal in a basic medium, at a temperature of from about -10.degree. to +150.degree. C. The product gives cyclohexanedione-(1,4), on acid hydrolysis, which is a valuable starting product for various syntheses, for example for tetracyanoquinodimethane, a desired compound in the field of semiconductors.Hydroquinone dimethyl ether, which is a valuable intermediate for the dyestuff preparation, is obtained from cyclohexanedione-(1,4)-tetramethyl diketal by catalytic dehydrogenation.
    • 通过在约-10℃至+ 150℃的温度下在碱性介质中对对苯醌四甲基二缩酮进行催化氢化,得到式“IMAGE”的环己二酮 - (1,4) - 四甲基二缩酮。 环己二酮 - (1,4),其是酸性水解,其是用于各种合成的有价值的起始产物,例如四氰基醌二甲烷,半导体领域中期望的化合物。 作为染料制备的有价值的中间体,氢醌二甲醚由环己二酮 - (1,4) - 四甲基二缩酮通过催化脱氢得到。
