yellowish or yellow-red vitreous, insoluble in water, but soluble in organic solvents, such as acetone, ethyl ether, ethanol, ethyl acetate, turpentine, benzene and xylene. Rosin also has the crystallization characteristics, easy to produce crystallization phenomenon, in acetone and other organic solvents will have a crystallization trend, the crystallization critical temperature of about 100. In addition to its easy oxidation and isomerization reaction, it also has double bond reaction of disproportionation, hydrogenation, addition and polymerization. At the same time also with esterification, alcoholization, salt, decarboxylation, aminolysis and other carboxyl reaction.
The Rosin removed from the pine tree is added into the reactor, heated and melted, and then water vapor is passed through, steam distillation is carried out, and the residual liquid of turpentine is distilled out, and filtered at about 210 ℃, the crystals were cooled to give a finished product. Alternatively, the pine pieces may be crushed, screened, and impregnated with gasoline, and the impregnated liquid may be filtered, decolorized, the solvent recovered, and distilled under reduced pressure to obtain a finished product.
In the process of making paper used as sizing compound, can also be used as pesticide emulsifier, textile sizing agent, lubricant of building materials, plastic, rubber plasticizer, coating drying agent.
