Kinetics of gum rosin oxidation under 365 nm ultraviolet irradiation
Monatshefte Für Chemie, 2013The oxidation of gum rosin was performed on a continuous-experiment apparatus under 365 nm ultraviolet (UV) irradiation. The kinetic constant for the oxidation of gum rosin was determined by UV spectrophotometry. The effects of different temperatures and light intensities on the oxidation rate constant were investigated.

Determination of Metal and Semimetal Elements in Chinese Gum Rosin by ICP-OES
Advanced Materials Research, 2013Chinese gum rosin were digested by microwave-assisted sample digestion, and then the metal and semimetal elements in it were detected by inductive coupled plasma optical emission spectrometer (ICP-OES). Most metal and semimetal elements mass fractions in gum rosin are less than 5.0mg/kg, among which mass fractions of Al, Ca, Fe, Mg, Na are relatively ...

Allergic contact dermatitis caused by gum rosin and wood rosin in Tako‐no‐Suidashi ointment
The Journal of Dermatology, 2011AbstractTako‐no‐Suidashi ointment (TSO) is an old Japanese over‐the‐counter drug, used for the drainage of infectious pustular disease, such as furuncles, carbuncles and infectious atheroma, although whether it works well or not is unknown. The ingredients of the TSO compound commonly include rapeseed oil, gum rosin, wood rosin, Japanese wax, paraffin,

Rosin and Other Natural Resins and Gums
2022Natural resins refer to noncrystalline solid or semi-solid amorphous materials or viscous liquid sticky substances produced by plants. They are typically transparent or translucent and are mostly yellowish to brown in colour. Natural resins are formed in plant secretions and are soluble in various organic liquids but not in water.

Gum rosin (colophony): A suitable material for thermomechanical modelling of the lithosphere
Tectonophysics, 1992We investigate the use of a ductile material with temperature-sensitive viscosity for thermomechanical modelling of the lithosphere. First, we consider the scaling of mechanical and thermal properties. For a normal field of gravity, the balance of stresses and body forces sets the stress scale, in proportion to the linear dimensions and the densities ...

An industrial steam distillation: Separation of rosin and turpentine from pine gum
Journal of Chemical Education, 1975Procedure for converting a tacky intractable mass - pine gum - into two recognizable and useful materials - a fragrant water-white liquid (turpentine) and a hard amber-colored resin (rosin).
