Embodiment 1
[0053] Embodiment 1: take by weighing La(NO 3 ) 3 ·6H 2 O 35.1mg (0.081 mmol) in a beaker, add 2.5mL aqueous solution, heated until fully dissolved and uniform. Weigh 10 mg (0.0081 mmol) of TMeQ[6], add 2.5 mL of aqueous solution and heat to 70°C, shake for several minutes to clarify the solution, inject the TMeQ[6] solution into the above mixed solution, shake well, and let it stand for nearly 40 days. Colorless and transparent crystals appeared, and the yield was 35-45%. Under the same conditions, TMeQ[6] and Ce(NO 3 ) 3 ·6H 2 O nearly 40 days to form colorless transparent crystals, the yield of 40 ~ 45%. Its structural formula is [(C 40 h 44 N 24 o 12 )Ln(H 2 O) 8 (NO 3 )]·2(NO 3 )·x(H 2 O), x=7-10.
Embodiment 2
[0054] Embodiment 2: take by weighing Pr(NO 3 ) 3 ·6H 2 O 35.4 mg (0.081 mmol) in a beaker, add 2.5 mL of aqueous solution, heat until fully dissolved and uniform, weigh TMeQ[6] 10 mg (0.0081 mmol), add 2.5 mL of aqueous solution, heat to 70 ° C, shake for several minutes, and make The solution was clarified, and the TMeQ[6] solution was injected into the above-mentioned mixed solution, shaken up, and left to stand for nearly two weeks, and a colorless transparent crystal appeared, with a yield of 50-60%. Nd(NO 3 ) 3 ·6H 2 O has formed colorless transparent crystals in the past week, with a yield of 50-60%, and its general structural formula is [(C 40 h 44 N 24 o 12 ) Ln (H 2 O) 8 ] 3Cl x(H 2 O), x=7-10.
Embodiment 3
[0055] Embodiment 3: take by weighing Sm (NO 3 ) 3 ·6H 2 O 36.1 mg (0.081 mmol) in a beaker, add 2.5 mL of aqueous solution, heat until fully dissolved and uniform, weigh 10 mg (0.0081 mmol) of TMeQ[6], add 2.5 mL of aqueous solution, heat to 70 ° C, shake for several minutes, make The solution was clear. Inject the TMeQ[6] solution into the above mixed solution, shake it well, and let it stand for nearly 24 hours, and a colorless transparent crystal appears, with a yield of 60-70%. Tb, Dy, Ho, Er, Tm, Yb, Lu and other rare earth salts form colorless and transparent crystals with a yield of 60-70%. Its structural formula is [(C 40 h 44 N 24 o 12 )Ln (H 2 O) 8 ] ·3Cl ·x(H 2 O), x=7-10.

Abstract
The invention discloses a symmetrical tetramethyl cucurbituril and rare earth coordination compound and addition compound and a heavy and light rare earthseparation method thereof and belongs to the field of a metal and organic supramolecular polymer and synthesis and application thereof. Symmetrical tetramethyl cucurbituril and rare-earth metal form into the symmetrical tetramethyl cucurbituril and rare earth addition compound and coordination compound under a neutral or acidic environment. The invention discloses a symmetrical tetramethyl cucurbituril and rare earth coordination compound and addition compound synthetic method, synthesizes a series of symmetrical tetramethyl cucurbituril (TMeQ[6]) and rare earth addition compounds and coordination compounds and is used for separating the rare earth according to different symmetrical tetramethyl cucurbituril and rare earth addition compound and coordination compound generation conditions and crystallization times of the rare earth. The synthesis method is simple in operation and high in yield.
Description
technical field [0001] The invention utilizes the synthesis of symmetrical tetramethyl six-membered cucurbit ring-rare earth complexes, adducts and methods for separating light and heavy rare earths, belonging to the field of metal-organic supramolecular polymers and their synthesis methods. Specifically, the properties and time sequence of complexes and adducts formed by symmetrical tetramethyl six-membered cucurbit rings and rare earths are different, and light and heavy rare earths are separated by using the properties of complexes and adducts. Background technique [0002] Lanthanides usually show similar chemical properties originating from the contraction of lanthanides. The structure and properties of the complexes formed by the combination of most ligands and series of rare earths are very similar. In particular, lanthanide metal ions exhibit high coordination numbers and easy The exchange characteristics make the lanthanides and their complexes difficult to separate...
