Abstract A simple analytical method for the determina‐tion of the neutrals (nonacidics) in tall oil fatty acids, gum and wood rosin has been developed. The method is based on the use of Chromatogra‐phic techniques for the separation of the acidic from the nonacidic fraction by using alumina as the adsorbent and acetone as the solvent. Data are presented which show good agreement between a calculated theoretical nonacidic content and the amount actually found by the chromatographie procedure as well as the standard AOCS procedure for unsaponifiables.
