Practically insoluble in water, in glycerol, and in propane-1,2-diol, but
soluble in varying proportions in certain organic solvents, depending upon
the ethoxyl content. Ethyl cellulose containing less than 46-48% of ethoxyl
groups is freely soluble in tetrahydrofuran, in methyl acetate, in chloroform,
and in aromatic hydrocarbon ethanol mixtures. Ethylcellulose containing 46-
48% or more of ethoxyl groups is freely soluble in ethanol, in methanol, in
toluene, in chloroform, and in ethyl acetate.
