摘要
本文主要考察了以对甲苯磺酸为催化剂,双环戊二烯经过水合制得羟基二氢双环戊二烯。通过正交试验考察了蒸馏水/双环戊二烯(摩尔比),反应时间,反应温度及对甲苯磺酸(质量比)等主要因素对实验的影响,确立了最佳的工艺条件为:蒸馏水/双环戊二烯(摩尔比)为10:1,反应时间是9小时,反应温度是100℃,对甲苯磺酸质量分数是1%。在此条件下产品收率可达到83%,经减压蒸馏之后物质纯度可达到97%。并对所得到的产品进行折光率测定和红外谱图表征,确定为目的产品。
In this experiment,hydroxy-dihydro dicyclopentadiene was obtained by hydrating dicyclopentadiene and p-Toluenesulfonic acid as catalyst.Through orthogonal experiment the effects of some factors,such as the mol ratio of water and dicyclopentadiene,reaction time,reaction temperature and the solution of p-Toluenesulfonic acid are reviewed to choose the optimal process conditions.The chosen process conditions were：The mol ratio of water and dicyclopentadiene is 10：1, the reaction time was nine hours,the reaction temperature was 100℃,the mass percentage of p-Toluenesulfonic acid was 1%.In the presence of those conditions,the rate of production can reach to 83%.The purity of the material can reach to 97%after distilled in vacuum.The determining products were comfirmed through the index of refractive and the characterization of infrared spectra.
