摘要： An object of the present invention is to provide a high-purity aromatic methyl alcohol compound having reduced a bis(arylmethyl)ether compound as a side product mixed thereinto and a high-purity aromatic methyl alcohol composition having excellent preservation stability and methods for producing them.The object of the present invention is achieved by a method for producing a high-purity aromatic methyl alcohol compound, which comprises obtaining a high-purity aromatic methyl alcohol compound in high yield from an aromatic methyl alcohol-containing crude product by subjecting the crude product to distillation in the presence of an anti-decomposition agent. Further, the object for the preservation stability is achieved by producing a high-purity aromatic methyl alcohol composition using the obtained high-purity aromatic methyl alcohol compound.
