Abstract
Inventia se refera la un procedeu de obtinere a surselor alternative de combustibil ecologic pur.Procedeul propus de obtinere a esterilor metilicidin ulei de rapita include transesterificarea uleiului de rapita cu alcool metilic, luati in raportstoechiometric in prezenta hidroxidului de potasiu, separarea fazelor amestecului si indepartarea catalizatorului rezidual. Noutatea inventiei constain aceea ca inainte de introducerea alcoolului metilic la uleiul de rapita se adauga 4…5% de glicerina si se amesteca la temperatura de 25°C. Transesterificarea se efectueaza la temperatura de 60°C si presiunea de 12…15 mPa, iar indepartarea catalizatorului rezidual se efectueaza la temperatura de85°C prin spalare cu apa in cantitate de 10% fatade masa uleiului initial. The invention relates to a process for obtaining alternative sources of pure ecological fuel. The proposed process for obtaining methylicidine esters of rapeseed oil includes the transesterification of rapeseed oil with methyl alcohol, taken in the stoichiometric report in the presence of potassium hydroxide, the separation of the mixing phases residual. The novelty of the invention is that before the introduction of methyl alcohol into rapeseed oil, 4 ... 5% of glycerin is added and mixed at 25 ° C. Transesterification is carried out at a temperature of 60 ° C and a pressure of 12 ... 15 mPa, and the removal of the residual catalyst is carried out at a temperature of 85 ° C by washing with water in an amount of 10% of the initial oil mass.
