Rosin oil

Rosin oils have been used in the rubber industry for many years. Because their quality characteristics could vary significantly, their use declined with a change in the quality philosophy of the rubber industry, which began in the 1980s. Now new rosin oil products are being offered with better assurances of consistent chemical uniformity. 

Proprietary rosin oil blends are used mainly in the tire industry and in belting as a less expensive alternative to using more expensive phenolic tackiflers with aromatic process oil. Rosin oil functions both as a tackifier and as a processing oil for rubber compounds usually based on general-purpose elastomers. As discussed earlier, environmental concerns are now associated with the use of aromatic oils. 

Usually these rosin oil blends are made strictly for use In the rubber industry. However, pine rosin and pine tar are commonly used by the adhesives industry. Also tall oil (byproduct from paper manufacture) Is used as a feedstock In destructive distillation to manufacture various fatty acid and rosin products. 

Rosin oil is essentially an economical alternative to using more expensive phenolic tackiflers with aromatic or naphthenic processing oil. During the 1980s and 1990s there was a period of declining use. However, with improvements in the quality

Pine trees, chiefly Pinus palustris and Pinus caribaea, contain an oleoresin (a mixture of essential oils and resins) which can be tapped or removed by extraction or distillation to yield a number of commercially significant products  

Rosin is chiefly abietic and pimaric acids, organic acids of the formula C10H29COOH with a phenanthrene group. Salts of rosin acids resinates) are easily formed with metals such as aluminium resinate. They are used as paint driers and as catalysts. 

Pine oil, rosin oil, and turpentine are all flammable and combustible liquids. Resinates are also dangerous fire risks.

Many similar hydrocarbon duids such as kerosene and other paraffinic and naphthenic mineral oils and vegetable oils such as linseed oil [8001-26-17, com oil, soybean oil [8001-22-7] peanut oil, tall oil [8000-26-4] and castor oil are used as defoamers. Liquid fatty alcohols, acids and esters from other sources and poly(alkylene oxide) derivatives of oils such as ethoxylated rosin oil [68140-17-0] are also used. Organic phosphates (6), such as tributyl phosphate, are valuable defoamers and have particular utiHty in latex paint appHcations. Another important class of hydrocarbon-based defoamer is the acetylenic glycols (7), such as 2,4,7,9-tetramethyl-5-decyne-4,7-diol which are widely used in water-based coatings, agricultural chemicals, and other areas where excellent wetting is needed.

Rosin. Rosin is used mainly in some modified form. Because the abietic-type acids in rosin each contain a carboxyl group and double bonds, they are reactive and can be used to produce salts, soaps, esters, amines, amides, nitriles, and Diels Alder adducts and they can be isomerized, disproportionated, hydrogenated, dimerized, and polymerized. When destructively distilled, rosin produces a viscous liquid, termed rosin oil, used in lubricating greases. 

Rosin or Rosin Oils Shake a 2-mL sample in a test tube with 5 to 10 mL of solvent hexane, allow the liquids to separate, decant the hexane layer, which is just slightly colored, into another test tube, and shake it with an equal volume of 1 1000 cupric acetate solution. The mixture does not turn green. 

Derivation By heating copper sulfate and rosin oil and filtering and drying the precipitate. 

Derivation By heating a solution of lead acetate and rosin oil. 

Derivation By boding manganese hydroxide, rosin oil, and water. 

Derivation By fractional distillation of rosin, that portion distilling above 360C being rosin oil.
