A novel spectrophotometric method for determining the acid number of tall oil
1995
Sithole, B.B.
A spectrophotometric procedure for the determination of the acid number of tall oil has been developed. The procedure involves dissolution of a known weight of tall oil sample in acetone followed by spectrophotometric determination of total free fatty and resin acids in the solution after prior complexation of the acids with cupric ions. The total free fatty and resin acids values of tall oils, as determined by the spectrophotometric procedure, correlate well with the acid numbers of the tall oil samples. This correlation affords an alternative rapid method for determining the acid number of tall oil.
