Rosin — hard, brittle, vitreous transparent resin light yellow (is more rare dark red) colors, the component of resinous substances of coniferous trees remaining after otgonka from resinous substances of turpentine.
Rosin is well dissolved on air, alcohol, acetone, turpentine and benzene, it is worse — in gasoline, kerosene and furfural; it is not dissolved in water. Softening point of rosin of 52 - 70 °C; temperature of boiling 250 °; heat capacity 0, 54 kcal/kg; heat conductivity 0, 11 kcal/m of hour hail; latent heat of melting 15, 8 kcal/kg; expansion coefficient of the melted rosin 0, 055; heating capacity of 9074 - 9171 kcal/kg; acid number 150 - 175.
Rosin consists their resin acids (80 - 95% ) having the general formula C19H29COOH and unsaponifiables (5 - 12% ) which contain methyl chavicol, stilbene derivatives, terpenic dimeasures, aldehydes and mix of hydrophenanthrene hydrocarbons. With mineral and organic bases rosin gives salts — rosinate soap (for example, C19H29COONa), and with different hydroxyl compounds — resin esters and other valuable products. Condensation of rosin with cutting phenolic formaldehyde resin at 290 ° receive albertol; at their etherification different alcohols form number of valuable pitches.
Depending on type of raw materials and way of receiving distinguish the following types of rosin: zhivichny, extraction and tall. Gum rosin is received turpentine otgonka from the purified gallipot. This type of rosin contains 5 - 7% of unsaponifiables and practically does not contain fatty acids. Wood rosin receive extraction by organic solvents (most often gasoline) the crushed resinous wood of coniferous trees (usually pines ordinary). This type of rosin differs from zhivichny in more dark color, has the lowered acid number (150 - 155), softening point 52 - 58 °, the content of fatty acids to 12% . At clarification of wood rosin of its property and value are similar to zhivichny. Tall rosin is received differential distillation of tall oil.
In our assortment there is large number of chemical raw materials which is applied in different areas of the industry and in life. You can buy rosin which price makes a reservation in individual order from us and many other things can vary depending on the volume of the order also.
Rosin (in other words, kolofonsky pitch) is amorphous, brittle, vitreous substance from dark red and claret till light yellow color. In the nature is part of pitches of different coniferous trees and it is got from gallipot (resinous substance of terebenthene which is emitted at wound or cut of trees of coniferous breeds) owing to processing of the crushed wood by solvents, turpentine otgonka from resinous substances or distillation of tall oil.
Rosin is perfectly dissolved in organic solvents, such as chloroform, ether, benzene, acetone, alcohol, it is a little bit worse - in furfural, gasoline, kerosene. In water it is not soluble. Temperature of melting depends on composition of pitch and boiling temperature - 250 °C fluctuates ranging from 50 - 70 °C or 100 - 130 °C. In 80 to 95% of structure resin acids which main component is abietic acid prevail. Other part is not saponifiable acids which may contain mix of hydrophenanthrene hydrocarbons, dimeasures and aldehydes, stilbene derivatives and methyl chavicol.
Depending on ways of receiving and type (structure) of raw materials distinguish tall, extraction and gum rosin. In the industry pine rosin is most often applied (extraction) which is got by extraction by organic solvents of resinous wood of ordinary pine.
Pine rosin is one of main products of production of forest chemical industry. It is applied in production of rosinate soap, ether, valuable pitches, sealing wax, varnishes, linoleum, ointments, putties, sticky substances, plasters, plastic, lubricating oils, glueings of paper, isolation of electrocables and many other.
In the food industry colophonic ethers are registered as E915 - food additive. Rosin (pine, tall, zhivichny) and its derivatives use for gluing of cardboard and paper, production of rubber, rubber, imitation leather, mastics, paints. Also rub with rosin bows and strings of musical instruments, pointes of ballerinas and footwear of dancers to prevent sliding.
Natural rosin which you can buy right now is presented on our website or carry out reserve.
