Abstract Vapor pressure vs. H2O content studies demonstrate that phosphorylcholine chloride calcium salt forms two hydrates, a monohydrate and a tetrahydrate, in the range 0–4 mol H20 mol−1 of salt; there is no dihydrate or trihydrate. Equilibrium vapor pressure measurements show that ΔH0 of dissociation per mol H20 lost is greater for the tetrahydrate (16.08 kcal mol−1) than for the monohydrate (12
