Norharmane prototropism in choline chloride-based deep eutectic solvents
3-phenylpropionic acid, and malonic acid, respectively, only cationic form is supported. As the cationic form is preferred more over the neutral form of norharmane in the excited-state, DESs with HBDs tetraethylene glycol, 3-phenylpropionic acid, and malonic acid, respectively, support only cationic form in the excited-state. DES with glycerol also supports only the cationic form in the excited-state, DES with
The present invention provides a method for the production in an electrochemical cell of one or more of graphene, graphite nanoplatelet structures having a thickness of less than 100 nm, and graphane, wherein the cell comprises: (a) a negative electrode which is graphitic; (b) a positive electrode which may be graphitic or another material; and (c) an electrolyte selected from (i) an ionic liquid; (ii) a deep eutectic solvent; and (iii) a solid ionic conductor, optionally further comprising (iv) one or more ionic species, wherein the amount of (i), (ii) or (iii) and (iv) is greater than 50 wt % based on the total weight of the electrolyte; and wherein the electrolyte includes a mixture of different cations; and wherein the method comprises the step of passing a current through the cell to intercalate ions into the graphitic negative electrode so as to exfoliate the graphitic negative electrode.

Provided are an oxovanadium phosphate catalyst, and a preparation method and an application therefor. The method includes: 1) mixing and reacting a vanadium source, a choline chloride-organic carboxylic acid eutectic solvent, and alcohol; 2) mixing the obtained reaction product with a phosphorus source, raising the temperature to a temperature higher than the melting point of the eutectic solvent, and continuing the reaction to obtain an oxovanadium phosphate precursor; and 3) calcining to obtain the oxovanadium phosphate catalyst. The alcohol is: benzyl alcohol or a mixture of C3-C8 monohydric alcohol and benzyl alcohol. The present method uses a green and inexpensive eutectic solvent to strengthen the preparation of oxovanadium phosphate catalyst, avoids the disadvantages of the prior art, and overcoming the problems of low yield and poor selectivity when used in a reaction to prepare maleic anhydride by catalytic n-butane selective oxidisation.
