Cellosolve: purification procedures for

Wherever possible aqueous solutions are preferred, but substances of low solubility prevent the use of water as a solvent and consequently the solvents normally used are aqueous alcohols, dioxane-water or Cellosolve-water mixtures. Sometimes even nonaqueous solutions are used (e.g. glacial acetic acid, N,N -dimethylformamide, benzene-methanol mixtures etc.). Usually it is necessary to purify the solvent in order to prevent contamination by substances which give waves in the same potential range as the substance under examination. Often procedures developed for the purification of solvents for spectrophotometric purposes have proved useful.
