A process for preparing a polyhydric alcohol according to the invention comprises subjecting a polyhydric alcohol compound having protected hydroxy group(s) to microwave irradiation in the presence of basic compound(s) or acid(s) having an acid dissociation exponent (pKa) of −8 to 3 at 25° C. to remove the protecting groups of the hydroxy group of the polyhydric alcohol compound. The invention can provide an industrially advantageous process for preparing polyhydric alcohols by readily removing protecting group(s) from protected hydroxy group(s) of polyhydric alcohol compounds.
根据该发明,制备多羟基醇的方法包括将具有受保护羟基的多羟基醇化合物置于存在具有25°C下酸解离指数(pKa)为-8至3的碱性化合物或酸性化合物的微波辐射中,以去除多羟基醇化合物的羟基的保护基。该发明可以通过轻松去除多羟基醇化合物中受保护羟基的保护基,提供一个工业上有利的制备多羟基醇的方法。
