发明名称 PROCESS FOR MAKING MONOACETALS OF HYDROQUINONE.
摘要 <p>The present invention is for a process for preparing monoacetals of hydroquinone wherein said process provides for higher yields of greater purity. Said process utilizes a two-step reaction wherein a protected hydroquinone is reacted with an enol ether to form a protected intermediate. Upon hydrogenolysis of said intermediate, a final product, monoacetal hydroquinone, is formed having higher degree of purity and in greater yields than the yields attributed to reactions known in the art.</p>
