PP-55PRODUCTION OF KETAL OF GLYCERIN – POTENTIAL MOTORFUEL WITH HIGH ANTIKNOCK PROPERTIESMaximov A.L., Shlyakhtitsev D.S., Nekhaev A.I.A.V. Topchiev Institute of Petrochemical Synthesis RAS, 119991 Moscow,Leninsky prospect, 29, nekhaev@ips.ac.ruThe problem of search of renewable energy sources arises because of theincreasing consumption of fuels and limitedness of petroleum reserves. One ofinexhaustible sources for fuel producing is vegetable biomass of our planet.Glycerin is easily generated by hydrolysis of natural oils and also as the largetonnageco-product of interesterification of vegetable oils with methanol for thepurpose of production of biodiesel, which is a substitute for petroleum diesel fuel.Acetone is an available and relatively cheap product of petrochemical synthesisand also the co-product of biotechnological production of biobutanol. Ketal, that is aproduct of reaction between acetone and glycerin, is not only a good motor fuel, butalso possesses high antiknock properties.Interaction between acetone and glycerin was led in flow reactor heated bycylindrical electrical oven. Initial products were fed into mixing junction with highpressurepumps. Reaction products were identified by the instrumentality ofchromatography-mass spectrometric method, current analyses were made withchromatograph Kristalux-4000M.As catalytic agents were tested cationite KU-2, zeolites β, ZBM, NaX. The highestproduct yields were achieved by using of zeolite β.OHOH+O-H 2OOOOHOH145
