Embodiment 1

[0019] (1)C 60 h 36 Synthesis

[0020] In a 250ml container, mix 50mg of C 60 Dissolve in 50ml ethylenediamine solution, stir to C 60 Dissolve completely, then add 1.64g of tert-butanol and 0.15g of lithium, stir vigorously until the reaction solution turns white completely, then stop stirring; then pour the reaction solution into 100mL of ice water and stir to room temperature. Then extracted with toluene (3×50mL), washed with brine and dried (Na 2 SO 4 ), evaporate toluene under reduced pressure to obtain a light yellow solid, which is the target product C 60 h 36 .

Embodiment 2

[0022] (1)C 60 h 36 Synthesis

[0023] In a 250ml container, mix 50mg of C 60 Dissolve in 70ml hexamethylphosphoric triamide solution, stir to C 60 Dissolve completely, then add 1.64g of tert-butanol and 0.46g of sodium, stir vigorously until the reaction solution turns white completely, then stop stirring; then pour the reaction solution into 200mL of ice water and stir to room temperature. Then extracted with toluene (3×80mL), washed with brine and dried (Na 2 SO 4 ), evaporate toluene under reduced pressure to obtain a light yellow solid, which is the target product C 60 h 36 .

Embodiment 3

[0025] (1)C 60 h 36 Synthesis

[0026] In a 250ml container, mix 50mg of C 60 Dissolve in 50ml diethylenetriamine solution, stir to C 60 Dissolve completely, then add 1.02g ethanol and 0.15g lithium, stir vigorously until the reaction solution turns white completely, then stop stirring; then pour the reaction solution into 100mL ice water and stir to room temperature. Then extracted with toluene (3×80mL), washed with brine and dried (Na 2 SO 4 ), evaporate toluene under reduced pressure to obtain a light yellow solid, which is the target product C 60 h 36 .

Abstract

The invention particularly relates to a new type composing method of Fuller alkene group oxygen storage material. In reactor, C60 is dissolved in fatty amine or polar aprotic organic solvent, under inert gas protection, adding proton source reagent and alkali metal in room temp. then stirring until that solution become to white completely; then pouring reaction agent into ice water and stirring until it to room temp. the product distillation to obtain end product C60H36, the quantity of proton source reagent and alkali metal added in reaction process is 100-300 times of C60 mole quantity. In the invention, whole composing process is proceeded in room temp.

Description

technical field [0001] The invention belongs to the field of material chemistry, in particular to fullerene-based hydrogen storage materials C 60 h 36 synthetic method. Background technique [0002] C 60 h 36 is C 60 A highly hydrogenated derivative of , is a promising new hydrogen storage material. [0003] About C 60 h 36 Synthesis, there have been related research reports. Smalley R.E. in the United States first synthesized C by Birch reduction in 1990. 60 h 36 , the method is to reduce C with lithium metal and tert-butanol in liquid ammonia 60 , so low temperature conditions are required in the reaction, and the synthesis process is cumbersome; German Rüchardt C. et al. also synthesized C by high temperature transfer hydrogenation 60 h 36 , used more expensive reagents in the reaction process, and related to sealing tube operation and high temperature, very inconvenient; Also once had Japanese patent (JP117174) report to prepare C with high temperature and hi...
