Disproportionated rosin amine Schiff base metal ( Cu 2 < / sup> Ni 2 < / sup > ) Preparation and catalytic properties of the complexes have been studied , including the following : 1 . Disproportionated rosin amine and salicylaldehyde raw materials, synthetic disproportionated rosin amine Schiff base, yield 85.7% ; then disproportionated rosin amine Schiff bases with Cu 2 , Ni 2 < / sup> reaction disproportionated rosin amine Schiff base - copper complexes and disproportionated rosin amine Schiff base - nickel complexes , the yields were 70.6% and 67.3% , nickel complexes have not been reported . By IR, UV, elemental analysis , TG- DTG analysis and other methods were used to characterize the synthesized compounds . The results show that the disproportionated rosin amine the Schiff bases Cu 2 , Ni 2 ions are respectively formed of N , O, and N , O four-coordination compound , both thermal decomposition temperature above 250 ℃ , are optically non-electrolyte . 2. H 2 O 2 as oxygen source , research disproportionated rosin amine Schiff base - copper complex catalyzed styrene , rosin , abietic acid , cyclohexene , isoprene ene oxidation reaction, discussed the kind of solvent , the influence of the amount of catalyst, the amount of oxidant , the reaction temperature and reaction time on the catalytic oxidation reaction , to draw the appropriate conditions of the catalytic oxidation reaction . Experimental results show that the dioxane solvent Schiff alkali - copper complex amount of 0.1-0.5% , times dropwise H 2 < / sub > O 2 80 ℃ reaction 6 hours, and the conversion rate of the reaction was more than 70% , the conversion rate can reach 100% of abietic acid , a styrene , isoprene conversion was greater than 90% . 3. H 2 O 2 as oxygen source , disproportionated rosin amine Schiff base - nickel complexes catalyzed styrene , cyclohexene , isoprene , abietic acid oxidation the reaction carried out a study to explore the type of solvent , the amount of oxidant , reaction temperature and reaction time on the reaction . The results show that the 1,4 - dioxane as solvent , the Schiff base - nickel complexes added in an amount of 0.1 % , the reaction for 2 hours at 80 ℃ , styrene, cyclohexene, isoprene conversion rates were 72.4 % , 56.5% and 89.3% , abietic acid conversion rate can reach 100% .
