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.
根据本发明制备多元醇的工艺包括:在碱性化合物或酸解离指数(pKa)为-8 至 3 的酸存在下,在 25°C 的温度下,对具有受保护羟基的多元醇化合物进行微波辐照,以去除多元醇化合物羟基的保护基团。本发明可提供一种具有工业优势的制备多羟基醇的工艺,该工艺可轻松去除多羟基醇化合物受保护羟基上的保护基团。
