    • This disclosure provides a process for preparing an anhydrous chromium(III) halide complex, comprising contacting a chromium(III) halide hydrate, a water absorption agent, and a coordinating solvent, L, and forming a chromium(III) halide complex having the formula CrX3.mL, wherein X is a halide and m is the number of moles of L per mole of chromium. This process is exemplified in the preparation of the substantially anhydrous or anhydrous CrCl3(THF)3, the process comprising contacting CrCl3.6H2O, tetrahydrofuran, and 3 Å, 4 Å, 5 Å, 10×, or 13× molecular sieves; forming CrCl3(THF)3; and isolating the CrCl3(THF)3 having a water content of less than or equal to 100 ppm.
    • 本公开内容提供了制备无水氯化铬(III)络合物的方法,包括使卤化铬(III)水溶液,吸水剂和配位溶剂L接触,形成具有式 CrX3.mL,其中X是卤化物,m是每摩尔铬的L摩尔数。 该方法在制备基本上无水或无水的CrCl 3(THF)3时举例说明,该方法包括使CrCl3·6H2O,四氢呋喃和3,4,5,10x或13x分子筛接触; 形成CrCl 3(THF)3; 并分离出含水量小于或等于100ppm的CrCl 3(THF)3。
