And the peak at 26 is the methyl group which, of course, is joined to the rest of the molecule by a carbon-carbon single bond.

The presence of [signiﬁcant] unreacted biphenyl in our ﬁnal product can be ruled out by our melting-point and NMR analysis, indicating that it mostly reacted to completion and any remainder was removed in the water extraction. Any queries (other than missing content) should be directed to the corresponding author for the article. Technical support issues arising from supporting information (other than missing files) should be addressed to the authors.
A theoretical study using COSMO‐RS method further confirms that an optimum composition of biphenyl and diphenylmethane for the formation of eutectic mixture is 37:63 by mass, which is very close to the composition found experimentally.

The eutectic mixture was proved to be liquid at ambient temperature with a viscosity of 3.0 cP at 25 °C and a vapor pressure of 1.4 Pa at 25 °C, which potentially meets the requirements for an efficient hydrogen storage system. However, 1H-NMR spectrum for the … The eutectic mixture exhibited a superior activity for hydrogenation reactions conducted at 120 °C under 50 bar of H2 pressure in the presence of a Ru (5 wt %)/Al2O3 catalyst. 2O as a solvent, the accepted reference peak (δ) 0)is the methyl signal ofthe sodium salt of3-(trimeth- ylsilyl)propanesulfonicacid;one crystal ofthis was added toeach NMR tube. The 1H-NMR spectrum of the pure biphenyl compound shows peaks with maxima centered between 7 and 8 ppm, which are attributed to aromatic protons attached to the sp2 carbons of biphenyl (Figure S1, Supporting Informa-tion).
