3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Disproportionated rosin potassium soap is obtained by saponification of disproportionated rosin and potassium hydroxide, wherein disproportionated rosin potassium soap with a solid content of 80% is a brown
A color paste, disproportionated rosin potassium soap having a solid content of 25% is an amber liquid. The main chemical component is dehydrochlorinated potassium salt, the generation
The molecular formula is C19H27COOK.
4 Technical requirements
Disproportionated rosin potassium soap is divided into two grades K-80 and K-25 according to the solid content, and is also a special grade and a first grade.
