Procedure

The procedure of Example 6 was repeated except that no methanol was added to the starting crude vinylphenol and the alkali aqueous solution. A toluene solution of p-vinylphenol having the same purity (99.1 wt%) as in Example 6 was obtained as a product. However, for 60 hours after the extraction operation a large amount of scale deposited on the inner wall of the extraction tower and line 8, and, as a result, it was impossible to further continue the operation.
