Zusammenfassung:The invention relates to a process for preparing an additive for motor vehicle gas oils. According to the invention, the process consists of the following stages: etherification reaction between glycerine and 2-amino-ethanol under mechanical stirring, for 20 min, at 600 rpm, in the presence of Amberlit 15 type acid catalyst, at the environmental temperature, under nitrogen, heating to 65°C, for 4...8 h, with stirring at 600 rpm, mixture supply at balance into a reactive distillation column, at a pressure of 4 bar and the reaction zone temperature of 55...65°C, at a recycling ratio lower than 1, upon glycerine conversion of 91.6%, to result in a final product of the type glycerin ether-amino, with a purity of 98%, to be used, in a volume percentage of 0.01...1%, as an anti-pollution additive for preparing additivated motor vehicle gas oil. Invenţia se referă la un procedeu de obţinere a unui aditiv pentru motorine auto. Procedeul, conform invenţiei, constă în etapele: reacţia de eterificare dintre glicerină şi 2-amino-etanol sub agitare mecanică timp de 20 min la 600 rpm, în prezenţă de catalizator acid de tip Amberlit 15 la temperatura mediului, sub azot, încălzire la 65°C timp de 4...8 h cu agitare la 600 rpm, alimentarea amestecului la echilibru într-o coloană de distilare reactivă, la presiunea de 4 bari şi temperatura zonei de reacţie de 55...65°C, la un raport de recirculare mai mic de 1, rezultând cu o conversie a glicerinei de 91,6% produs final de tip eter-amino de glicerină cu puritate de 98% care se utilizează în procent volumetric de 0,01...1% ca aditiv antipoluare pentru realizarea motorinei auto aditivate.
