Solubilities of inorganic and metal organic compounds. Nearly half of the O6-H⋅⋅⋅O3 intermolecular hydrogen bonds could be broken by THF in the H2 O-THF co-solvent system, whereas the cleavage of O2-H⋅⋅⋅O6 intramolecular hydrogen bonds by H2 O was significantly inhibited. NLM It was found that the hydrate promoting effect of tetrahydrofuran is able to suppress the inhibiting effect of sodium chloride especially at lower concentration of sodium chloride. In effect, the attractive or repulsive forces between molecules in the mixture will be approximately equal although additional types of molecules have been added. What's more, its EINECS number is 231-598-3.
