Behavior of Glass-like and Mineral-like Phosphate Compounds with an Immobilized Chloride Mixture in Hydrogen Peroxide Solutions

Energies, 2022
A new type of high-level waste (HLW) is generated during pyrochemical reprocessing of mixed nitride spent uranium–plutonium nuclear fuel. Such waste is a spent electrolyte, which is a mixture of chloride salts containing approximately 25.7 wt.% LiCl + 31.

Cyclobenzaprinium chloride [PDF]

Acta Crystallographica Section E Structure Reports Online, 2011
In the title mol-ecular salt [systematic name: 3-(5H-dibenzo[a,d]cyclo-hepten-5-yl-idene)-N,N-dimethyl-propan-aminium chloride], C(20)H(22)N(+)·Cl(-), two cation-anion pairs make up the asymmetric unit. The dihedral angles between the mean planes of the two fused benzene rings of the cation are 49.5 (1) and 50.9 (1)°.
