Aromatic glycol compound and preparation method thereof

The invention provides an aromatic glycol compound. The aromatic glycol compound is iso-phthalic-bis(3-hydroxy-2,2-dimethyl propyl) ester. The preparation method of the compound comprises the following steps that dimethyl isophthalate and neopentyl glycol of which the molar ratio is 1mol:(4-15mol) react for 5-12 hours at 170-200 DEG C in the presence of a catalyst titanate; after the reaction is completed, excess neopentyl glycol is steamed out, and a crude product is subjected to column chromatography purification or is recrystallized in a solvent to obtain an iso-phthalic-bis(3-hydroxy-2,2-dimethyl propyl) ester product. 一种芳香族二醇类化合物，所述芳香族二醇类化合物为间苯二甲酸二(3-羟基-2,2-二甲基丙基)酯，其制备方法，包括以下步骤：将摩尔比为1mol：4～15mol的间苯二甲酸二甲酯和新戊二醇，在催化剂钛酸酯的存在下，在170℃～200℃的温度下发生反应5～12h；反应结束后，蒸出过量的新戊二醇，粗产品通多柱层析纯化或于溶剂中进行重结晶得到间苯二甲酸二(3-羟基-2，2-二甲基丙基)酯产品。
