专利摘要:
The present invention patent relates to a method for producing hydrogenated resin gum and to products produced thereby, pertaining to the chemical sector, and relates particularly to a method of partial catalytic hydrogenation of rosin (colophony) resin gum, from Pinus elliotti and Pinus tropicalis, for producing rosin that is less susceptible to oxygenation and pinane-rich turpentine, using palladium and nickel catalysts. The invention serves the market of rosin derivatives and resins, which currently has a demand for lighter coloured products which are more attractive to the end consumer of products thereof and are more resistant to oxidation from heat degradation and natural weathering, and also serves the market of fragrances, since the production of pinane offers novel synthetic alternatives different to those found using alpha- and beta-pinene. The present invention provides a method for producing hydrogenated resin gum and products produced thereby, wherein the hydrogenated rosin is produced by hydrogenation at 20-3.0 bar H2 of resin gum from Pinus elliotti and Pinus tropicalis.
