LIQUID FORMULATION FOR HYDROGEN STORAGE
The present invention relates to a liquid formulation comprising an amount greater than or equal to 50 wt % benzyltoluene and an amount of less than 0.5 mol % diphenylmethane. The invention also relates to the use of said formulation as LOHC for the production of hydrogen comprising less than 0.5 mol % diphenylmethane.

10 . A liquid formulation comprising:
an amount of not less than 50%, by weight of benzyltoluene (BT), relative to the total weight of the formulation, and
an amount of less than 0.5 mol % of diphenylmethane (DPM), relative to the total number of moles of BT+DPM.
11 . The formulation as claimed in claim 10 , comprising an amount of not less than 98% by weight of benzyltoluene.
12 . The formulation as claimed in claim 10 , comprising one or more other LOHC fluids obtained from petroleum products and/or from products synthesized from petroleum products, or else obtained from renewable products and/or from products synthesized from renewable products.
13 . The formulation as claimed in claim 10 , comprising one or more other LOHC fluids selected from the group consisting of dibenzyltoluene, diphenylethane, ditolyl ether, phenylxylylethane, mono- and bixylylxylenes, 1,2,3,4-tetrahydro(1-phenylethyl)naphthalene, diisopropylnaphthalene, monoisopropylbiphenyl, phenylethylphenylethane, N-ethylcarbazole, phenylpyridines, tolylpyridines, diphenylpyridines, dipyridylbenzenes, dipyridinetoluenes, and mixtures of two or more thereof, in any proportions.
14 . The formulation as claimed in claim 10 , comprising at least 50% by weight of benzyltoluene and dibenzyltoluene, relative to the total weight of benzyltoluene and dibenzyltoluene.
15 . The formulation as claimed in claim 10 , comprising from 80% to 99.9% by weight of benzyltoluene and from 0.1% to 20% by weight of dibenzyltoluene (relative to the total weight of benzyltoluene and dibenzyltoluene).
16 . The formulation as claimed in claim 10 , comprising an amount of not more than 0.4 mol %, of DPM, relative to the total number of moles of BT+DPM.
