[求助] 合成过程有点不懂已有4人参与

MWHAc-UIO-66.  Typically, ZrCl4 (150 mg, 0.644 mmol) was dissolved in acetic acid (5 ml, 87.36 mmol)/DMF(40 ml, 516 mmol) to give a clear solution and continuously stirred for half an hour. Then, BDC (120 mg, 0.723 mmol) was dissolved into the solution. Finally, this mixed solution with a molar ratio of DMF:HAc:BDC:ZrCl4 of 800:135:1.12:1 was placed into a microwave oven and irradiated at 100 °C for 2 hours. The product was centrifuged at 6000 rpm for 5 min, washed three times with ethanol and dried at 60 °C overnight. The yield (based on ZrCl4) was close to 90%.
MWBA-UIO-66.  MWBA-UIO-66 was prepared according to the above process, in which ZrCl4 was dissolved in a mixture of benzoic acid/DMF with 30 equivalents of benzoic acid. The after treatment used was the same as the above procedure. The yield (based on ZrCl4) was close to 85%.


MWBA-UIO-66 was prepared according to the above process, in which ZrCl4 was dissolved in a mixture of benzoic acid/DMF with 30 equivalents of benzoic acid.
这句话的意思是苯甲酸的含量是DMF的30倍吗?那就是1200mL  这么多吗?

调节剂苯甲酸30当量是相对于氯化锆而言的,和溶剂DMF 无关吧

是摩尔比,如上面所写acetic acid (5 ml, 87.36 mmol)/DMF(40 ml, 516 mmol) ,这样DMF是HOAc的5.9-6倍,如果DMF是benzoic acid的30 equiv的话,就是1克benzoic acid(8.2mmol), 20mL左右的DMF(0.25mol)

我还是没懂 是DMF是苯甲酸的30倍还是苯甲酸是DMF的30倍

感觉苯甲酸的摩尔数是DMF摩尔数的30倍。
