1,4-Benzenedimethanol → Benzaldehyde, hydroxymethyl-

Participants

Reaction Steps

167.0 g of sodium carbonate and 1200 g of distilled water were placed in a four-necked flask equipped with a reflux condenser, a lagged dropping funnel, a thermometer and a stirrer, and the atmosphere in the flask was replaced with nitrogen and then adjusted to 100° C. Next, 100 g of α,α,α'-trichloro-p-xylene having a purity of 90% by weight obtained in the same manner as in Preparation Example 1 were added dropwise thereto over 10 minutes. After an aging reaction was carried out for 10 hours, the resultant reaction solution was analyzed by the use of gas chromatography. As a result, it was found that the reaction solution was composed of 85% by weight of p-hydroxymethylbenzaldehyde, 4.8% by weight of p-xylylene glycol, 2.8% by weight of terephthalaldehyde and 7.4% by weight of the others.
