文摘
- •
Dilution enthalpies of l-carnitine in aqueous alkali halide solutions by ITC.
- •
The second virial coefficients of enthalpy (h2) have been calculated.
- •
The values of h2 increase with increasing molalities of aqueous salt solutions.
- •
The signs of h2 turn from negative in pure water to positive in salt solutions.
- •
The trends is ascribed to the salt effects on pairwise self-associations.
