Abstract
Invenţia se referă la un procedeu de obţinere a surselor alternative de combustibil ecologic pur.Procedeul propus de obţinere a esterilor metilici din ulei de rapiţă include transesterificarea uleiului de rapiţă cu alcool metilic, luaţi în raport stoechiometric în prezenţa hidroxidului de potasiu, separarea fazelor amestecului şi îndepărtarea catalizatorului rezidual.Noutatea invenţiei constă în aceea că înainte de introducerea alcoolului metilic la uleiul de rapiţă se adaugă 4…5% de glicerină şi se amestecă la temperatura de 25°C. Transesterificarea se efectuează la temperatura de 60°C şi presiunea de 12…15 mPa, iar îndepărtarea catalizatorului rezidual se efectuează la temperatura de 85°C prin spălare cu apă în cantitate de 10% faţă de masa uleiului iniţial.
