Description
Technical field the present invention relates to rosin catalyzed hydrogenation, particularly relates to a kind of non-precious metal catalyst that is used for rosin catalyzed hydrogenation.
Background technology rosin is the extremely abundant a kind of natural resin of nature, have anticorrosion, insulation, excellent characteristic such as bonding, be widely used in fields such as chemical industry, papermaking, coating, printing ink, insulating materials, but rosin exists some intrinsic shortcomings, as in solvent, have crystallization trend, easily autoxidation in air, softening point lower, when being used for the metal surface easily and metal chemically reactive etc.For eliminating these shortcomings, often need that rosin is carried out modification and handle.Foral is that rosin carries out the product that hydrogenation reaction obtains under catalyst action, is one of important modified product of rosin.It has advantages such as good in oxidation resistance, heat endurance height, fragility be little, of light color.Be widely used in industrial departments such as adhesive, scaling powder, rubber, coating, printing ink, papermaking, electronics, food.The catalyst that generally is used at present rosin catalyzed hydriding process is precious metals pd/C catalyst, though the researcher adopts base metal Cu, Ni etc. partly to replace the rosin catalyzed hydrogenation of Pd both at home and abroad in recent years, also useful Raney nickel (skeleton nickel) is as the research report of catalyst, but the best still Pd/C catalyst of hydrogenation effect.Subject matter has two aspects, and one is to use that the content of aluminium ion and iron ion increases in the product Foral of Raney Ni catalyst; The 2nd, because rosin hydrogenation is a reaction that is diffused as the control step, and Raney Ni (skeleton nickel) is because the preparation method has determined catalyst to have uneven hole, thereby its course of reaction there is considerable influence, equipment (especially agitating device) is had relatively high expectations, do not having great breakthrough aspect the rosin hydrogenation catalyst over nearly 50 years.
On the other hand, China's noble metal resource is very poor, and is required for satisfying fields such as domestic metallurgical industry, chemical industry, material industry, must spend a large amount of foreign exchange import noble metals every year.For realizing sustainable development, reduce the use amount of noble metal, the research and development non-precious metal catalyst substitutes noble metal catalyst and has crucial meaning.
Summary of the invention the object of the invention is to provide a kind of non-precious metal catalyst that is used for rosin catalyzed hydrogenation reaction, adopt this catalyst rosin hydrogenation reaction, it is short to have technological process, reaction pressure is lower, energy efficient, catalyst amount is few, abietic acid conversion ratio height, the measured characteristics of products obtained therefrom matter.Processing step is as follows:
