摘要: Ethylcellulose walled microcapsules, obtained from cyclohexane medium are heavily solvated with cyclohexane and tend to form lumps even after drying. Displacements of cyclohexane by pentane, hexane, heptane or octane or mixtures thereof during the isolation of the microcapsules gives a dry product which is essentially all discrete dry microcapsules.
