文獻(xiàn)1：
For  synthesis  of  MOF-235  at  first,  0.2 g  of  terephthalic  acid  and 0.205  g  of  FeCl3·6H2O  were  dissolved  in  60  mL  of  N,N-dimethylformamide  (DMF)  and  then  2  mL  of  the  reaction  solution  and  2  mL of  ethanol  transferred  into  a  Teflon-lined  autoclave  and  heated  at 358  K  for  24  h.  The  orange  crystals  were  washed  with  DMF/ethanol  mixture  and  dried.

文獻(xiàn)2：
An exact amount of terephthalic acid (0.205 g, 1.23 mmol; Sigma–Aldrich, 98%) was mixed with 60 mL of DMF (DC Chem., 99%). Then the mixture was stirred
for 10 min till a clear solution was formed. After that FeCl3·6H2O (0.200 g, 0.738 mmol; Duksan, 99.7%) was added into the solution and stirred for 5 min. The reactant mixture of 30 mL and 30 mL of ethanol (DC Chem., 96%) were loaded into a Teflon-lined autoclave, sealed and placed in a preheated electric oven (80C) for 1 day. Orange powder of MOF-235 was collected by centrifugation and was washed with a DMF/ethanol mixture at least three times. Then the product was dried overnight at 150 ◦C to remove DMF and then stored in a glass vial.

區(qū)別：
對(duì)苯二甲酸的用量不一樣，一個(gè)是0.2g；另一個(gè)是0.205g。
FeCl3·6H2O 也不一樣，一個(gè)是0.205g；另一個(gè)是0.2g。
加入順序不一樣，一個(gè)是先后順序加入；另一個(gè)是混合全部加入。
最后烘干方式不一樣，一個(gè)是自然烘干；另一個(gè)是加熱烘干。

才疏學(xué)淺 不知道哪種才是正確的
