AMINE CONTAINING COMPOUNDS AS CATALYST FORPRODUCING OF BIODIESEL FUELSMammadova T.A., Talibov A.H., Andryshenko N.K., Askerova E.N.,Veliyev X.R., Aliyeva Z.M.Petrochemical Unstitute name after Mamedaliyev, Baku, Azerbaijanmamedova.tarana@rambler.ruPP-34For the purpose to research more efficacious catalyst for reaction of etherificationof vegetable oils triglycerides, which are allowed at the same time to escapeproblems with soap-forming may be observed by using KOH, NaOH were researchedpyridine, piperidine, tetramethylammonium hydroxide, aminoguanydin carbonat.Experiments by produce of methylestersof sunflower oilwere spended at 50-80 °С,ratio methanol/oil 1:6 and reaction time 1-5 hours with various containing of catalyst.Among the investigated compounds tetramethylammonium hydroxide has themost activity. When containing of tetramethylammonium hydroxide in reaction systemis 0.1%, yield of alkyl esters is 30% and by further increasing of containing of catalysttill 0.3 - 05% (reaction time 1 hour) yield of alkyl esters increase to 76 and 98%accordingly. Further increasing of catalyst containing of is not expedient because theyield of alkyl esters in this time containing 98,3%.Quite enough activity in reactions of etherification of vegetable oils triglycerideshas the aminoguanydin carbonat, which provide the yield of esters more than 95%and at the same time it is the insoluble in spirits and oils solid powder, what is itsadvantage in comparison with the others catalysts as it allow to keep off separationand washing products from catalysts.Piperidine displays enough activity by containing of it in system 3%.Yield of alkyl esters by the using of pyridine contains no more than 54% even thecontaining of it more than 10%.123
