    • Provided are a method for preparing 3(4),7(8)-dihydroxymethylbicyclo[4.3.0]nonane to improve production yield, and the novel 3(4),7(8)-dihydroxymethylbicyclo[4.3.0]nonane prepared by the method which is used for preparing a conversion product used as a plasticizer and a lubricant. The method comprises the steps of reacting bicyclo[4.3.0]nona-3,7-dienol and a synthesis gas in the presence of a transition metal compound of group VIII in a periodic table containing a complex-bonded organic phosphorus compound and an excessive amount of an organic phosphorus compound in a uniform organic phase at a temperature of 70-160 deg.C and at a pressure of 5-35 MPa to obtain 3(4),7(8)-bisformylbicyclo[4.3.0]nonane; and hydrogenating the obtained 3(4),7(8)-bisformylbicyclo[4.3.0]nonane to prepare 3(4),7(8)-dihydroxymethylbicyclo[4.3.0]nonane.
    • 提供制备3(4),7(8) - 二羟基甲基双环[4.3.0]壬烷以提高产率的方法,以及由3(4),7(8) - 二羟甲基双环[4.3.0] 用于制备用作增塑剂的转化产物和润滑剂的方法。 该方法包括在含有复合键合的有机磷化合物的周期表和过量的复合键合的有机磷化合物的周期表中,使双环[4.3.0]壬-3,7-二烯醇与合成气在VIII族过渡金属化合物的存在下反应的步骤 在70-160℃的温度和5-35MPa的压力下在均匀有机相中的有机磷化合物的量获得3(4),7(8) - 二甲酰基双环[4.3.0]壬烷; 氢化得到的3(4),7(8) - 双甲基双环[4.3.0]壬烷制备3(4),7(8) - 二羟甲基双环[4.3.0]壬烷。
