Microemulsion - sol-gel TiO2 Photocatalyst characterization of agents
Reaction reaction time l00min, pressure 9MPa. 3 Conclusion The resin as raw materials to, Raney-Ni as catalyst, high temperature, high pressure catalytic hydrogenation of abietic acid were prepared to dihydro and tetrahydro hydrogenated abietic acid rosin-based products. The reaction conditions of temperature 170 ~ 200 ℃, pressure of 8-11MPa,Moncler pas cher, 3% -6% catalyst,glätteisen ghd, reaction time within 40-100min to dihydro and tetrahydro abietic acid and abietic acid content,uggs sale, that is the product of hydrogenated rosin The content analysis of indicators, designed the four factors and four levels of the orthogonal experiment. By variance analysis, that resin catalyzed hydrogenation of primary and secondary order factors: the amount of catalyst, temperature, time, pressure; optimum conditions for the 6% catalyst, 200oC,ugg boots España, 100min, 9MPa,timberland boots, in this condition, Through experiments in hydrogenated rosin content of the product can reach 88.7432%.
