摘要 为了实现以新橙皮苷为原料,在常温常压下催化加氢合成新橙皮苷二氢查尔酮的工业化生产,采用单因素试验对合成反应的关键工艺参数进行了研究。结果表明,当料液比m新橙皮苷∶V(NaOH)=1∶10,ρ(NaOH)=50 g/L,催化剂钯炭与新橙皮苷的质量比为1∶5,转速为500 r/min时,反应8 h后新橙皮苷二氢查尔酮的合成率可达到98%以上。 In order to realize the industrial synthesis of neohesperidin dihydrochalcone(NHDC) from neohesperidin via catalytic hydrogenation at room temperature and atmospheric pressure,some relevant parameters for industrial production have been studied by means of single-factor experiments.The conversion of neohesperidin to NHDC was over 98% under the optimum conditions,which are as follows: m(neohesperidin)∶V(NaOH) = 1∶10,ρ(NaOH)=50g/L,the mass ratio of neohesperidin to Pd/C catalyst=5,stirring speed=500r/min and reaction time = 8h.
