terbium, in your referenced post you say that a quick acetone wash can be used to purify cocaine HCL.
Derivative Type: Hydrochloride
Additional Names: Cocaine muriate
Molecular Formula: C17H21NO4.HCl
Molecular Weight: 339.82.
Percent Composition: C 60.09%, H 6.53%, N 4.12%, O 18.83%, Cl 10.43%
Properties: Crystals, granules, or powder; saline, slightly bitter taste; numbs tongue and lips. mp ~195°. [a]D -72° (c = 2 in aq soln pH 4.5). One gram dissolves in 0.4 ml water; 3.2 ml cold, 2 ml hot alcohol; 12.5 ml chloroform. Also sol in glycerol, acetone. Insol in ether or oils. Avoid heat in preparing soln as it decomposes. Preserve in well-closed, light-resistant containers.
Melting point: mp ~195°
Optical Rotation: [a]D -72° (c = 2 in aq soln pH 4.5)
it says in the merck that it is soluble in acetone. Is it just that it is so quick that it cant go into soln?
