Quaternary ammonium iodides are attractive choices because they generally have good activity, low cost, and solubility in the reaction and recovery processes. Simple quaternization of the wide variety of available tri(n-alkyl) amines with n-alkyl iodides allows optimization of the tetra(n-alkyl) ammonium iodide salt properties ...

Summary. Solubility, H NMR, DTA, and GPC all support the conclusion that pure graft copolymer is obtained by the present method of synthesis. The only purification necessary is removal of the silver salts. Properties of the neoprene-g-PTHF copolymers depend on composition and branch length and generally lie between those of the backbone and branch.

Because a balance between different salt properties needs to be taken into consideration in assessing the correct salt form to progress into drug development, some decision-making models have been developed to aid in the selection of an appropriate salt form. Gould described a salt selection process based on melting point, solubility, stability, wettability, etc. of various salt forms. However, in the absence of clear go/no go decisions at any particular stage of the salt selection process, this approach would lead to the...
