Introduction
Kolophonium, also known as rosin, is a natural resin derived from the sap of various pine trees, such as the Pinus sylvestris. It is a solid, brittle substance with a characteristic yellow to amber color and a slightly acrid odor. Kolophonium has been widely used for centuries in a variety of applications, including:
1. Physical and Chemical Properties
Kolophonium consists primarily of abietic acid (up to 90%) and other related diterpene acids. It is insoluble in water but soluble in organic solvents such as alcohol, ether, and turpentine.
