Oxidation of 2 6 Diisopropyl Naphthalene to 2 6 Naphthalenedicarboxylic Acid in Acetic Acid by Hybrid Nano Particles of Co Mn Immobilized on Calcined Bone and Pyrolyzed Wood Atefeh Mardani Ghahfarokhi a mardani ghahfarokhi@ch iut ac ir october 25 2011 Department of Chemistry Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Supervisor Mehran Ghiaci mghiaci@cc iut ac irAbstract Nowdays most of the researches are focused on metal nano particles They have unique properties onmagnetic electronic optical and chemical behavior compared to bulk materials because of their large surface areato volume ratio Transition metal nano particles have the high catalytic activites in organic reactions But the solublemetal nano particles have some problems such as recycling and separation of these catalysts from reactions Tosolve this problems it would be better to immobilizethem on suitable support materials and use them asheterogenous catalyst Therefore most of current researches and focused on modification of different supports forimobilization of metal nano particles However inorganic solids such as silica carbon clay and mixed oxides arewidely used to carry metal nano particles Liquid phase oxidation ofiso propyl aromatic hydrocarbones is a gratescientific technological and commercial importance In this project liquid phase oxidation of 2 6 Diisopropylnaphthalene 2 6 DIPN to 2 6 Naphthalene dicarboxylic acid 2 6 NDCA wad studied with hetrogenous catalystimmobilization of Co and Mn nano particles on bone and wood and impregnation methods which was promoted byKBr Also glacial acetic acid was used as solvent 2 6 Naphthalene dicarboxylic acid is building block of specialpolymers such as polyethylene naphthalate PEN that have improved heat resistance mechanical strength and usein electrical insulation application and can be used for manufacturing food containers for example Oxidation of 2 6 DIPN redound to produce 2 6 NDCA Co and Mn are famous and important catalysts for this oxidation reaction butbecause of high price of theses metals we were trying to perform this processing whit high yield of 2 6 NDCA whitlittle amount of Co and Mn With conversion particles catalyst to particles in nano scale yield of production 2 6 NDCA became high With immobilizing Co Mn in porous of wood and bone these particles convert to nanoparticles In this oxidation reaction KBr was used as a promoter Oxidation was performed under heat and pressure 2 6 DIPN 0 86 g KBr 0 1 0 3 g and catalyst 0 8 g were put in the reactor then acetic acid as solvent was addedtheme The reactor was adjoined with sources of molecular oxygen Oxygen 13 17 bar and heat 150 C 190 C were exerted in mixture of this reactor At reaction times of 12 hour at 190 C 200 C and p 17 bar 2 6 NDCA wasformed with high selectivity Keywords 2 6 diisopropyl naphthalene Oxidation nano catalyst 2 6 Naphthalene dicarboxylic acid
