Rosin is brittle and friable, with a faint
piney odor. It is typically a glassy
solid, though some rosins will form crystals, especially when brought into
solution. Rosin mainly consists of different resin acids, especially abietic
acid with general formula of C20H30O2
Insoluble in water; freely soluble in alcohol,
benzene, ether, chloroform, glacial acetic acid, oils, carbon disulfide, dilute solutions of
fixed alkali hydroxides. Low toxicity. Hard and friable at room temperature;
soft and very sticky when warm. Combustible.
Chief constituents: Resin acids of the abietic
and pimaric types, having the general formula of C20H30O2
, and having phenanthrene nucleus.
Melting and Flammability:
The practical melting point varies with different specimens, some
being semi-fluid at the temperature of boiling water, others melting at 100°C to
150°C. It is very flammable (Flashpoint 187ºC), burning with a smoky flame, so
care should be taken when melting it.
combines with caustic alkalis to form salts
(rosinates or pinates) that are known as rosin soaps.
