物理化學性質
Tall oil rosin is a product of crude tall oil distillation. The fraction of resin acids is collected from the lower part of the first distillation column and its content is represented by abietic, dihydroabietic, palustric, neoabietic, isopimaric and other acids. Aside from resin acids, the tall oil rosin contents also up to 6% of unsaponifiable matters. Depending on processing methods, the tall oil rosin delivered by Torgovyi Dom Lesokhimik differs in softening points. Presently, there are three types of tall oil rosin in production: with softening point 60 - 61oC, with softening point 63 - 64oC, and with softening point 65 - 66oC ("strong" rosin). These softening points are defined by type IKAR unit. Defining by "ring and ball" method gives higher softening points (by 3 degrees on the average).
