Definitions

  • the present invention relates to gasoil extenders for automotive use, and to the method for their preparation.
  • gasoil extenders se ⁇ lected in the class of dioxygenated derivatives of methane can increase the available amounts of gasoil for automotive use, and contemporaneously improve the quality thereof.
  • the extenders for gasoil for automotive use according to the present invention are selected in the class of di ⁇ oxygenated derivatives of methane, and have the general for mula
  • R. and R_ equal to or different from each other, 1 2 are straight or branched alkyl groups, having from 1 to 20, preferably from 2 to 10 carbon atoms, or alkoxyalkyl groups

  • R is an alkyl group having from 1 to 20, preferably from 2 to 10, carbon atoms, x be ⁇ ing comprised within the range of from 1 to 10.
  • the gasoil extenders according to the invention are to be added to gasoils in an amount comprised within the range of from 1% to 40% by volume of the volume of starting gas ⁇ oil, preferably of from 5% to 25% by volume.
  • the starting gasoils to which the gasoil extenders ac ⁇ cording to the invention are to be added comprise those having a distillation range comprised within the range of from 160 to 400°C. They have typically density comprised within the range of from 0.800 to 0.880 kg/l, cetane num ⁇ ber comprised within the range of from 35 to 60, turbidity temperature comprised within the range of from +10°C to -25°C.

Abstract

Un procédé permet de préparer des additifs pour le gasoil utilisé dans les véhicules automobiles. Les présents additifs pour gasoil sont sélectionnés parmi la classe des dérivés de méthane dioxygéné ayant la formule générale (I) dans laquelle R1 et R2, identiques ou différents, sont des groupes alkyles linéaires ou ramifiés ayant de 1 à 20 atomes de carbone, de préférence de 2 à 10 atomes de carbone, ou des groupes alkoxyalkyles de formule R1-(O-R)x-, dans laquelle R est un groupe alkyle contenant de 2 à 6 atomes de carbone, et R1 est un groupe alkyle contenant de 1 à 20 atomes de carbone, de préférence de 2 à 10 atomes de carbone, x étant compris entre 1 et 10. La préparation des additifs de gasoil s'effectue par la réaction d'un alcool ou d'un mélange d'alcools avec une formaldéhyde en présence d'un catalyseur acide homogène ou hétérogène dans le milieu de réaction.
