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
  • X 1 from 2 to 6 carbon atoms
  • 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.
  • gasoil extenders according to the present inven- tion can be used as a function of their characteristics to the purpose of:
  • a second object of the invention is the method for the production of the gasoil extenders as previously dis- c losed.
  • Alcohols are aliphatic, straight or branched, with a number of carbon atoms comprised within the range of from 1 to 20, preferably of from 2 to 10.
  • the glycols have a number of carbon atoms comprised within the range of from 2 to 6.
  • sulphuric acid ch lorosu Iphoni c ac ⁇ id, toluenesu Iphoni c acid, phosphoric acid
  • an acidic resin can be used, selected among the following ones :
  • reaction conditions are, as for the temperature, from room temperature up to reaction mixture boiling tem ⁇ perature.
  • water present or being formed during the reaction is continuously removed during the reaction course by azeotropic distillation, in particular by means of the addition of a hydrocarbon com ⁇ ponent suitable to form azeotropes, or by rectificat on in distillation column.
  • reaction mass is heated to boiling tempera ⁇ ture and, when all water formed in the reaction has been removed, the resin is filtered off, the filtrate is wash ⁇ ed with aqueous NaHCO (to remove the last traces of a- cidity), and is fractionated on tray column.
  • a product is obtained with (G.C.) purity greater than 99%, and with yields close to theoretical value.
  • a product is obtained with purity 99% and yield greater than 90%.
  • the three pos sible products (di i sobuty1-, i sobutyl-n-but I- and di-n- butyl-formal) are combined in one single fraction.
  • the ra ⁇ tio of alkyl chains in this fraction is practically iden ⁇ tical to that of charged alcohols.
  • the overall yield, cal ⁇ culated relatively to formaldehyde, is close to theoretic ⁇ al value.
  • n.butanol 60/40 iso/nor C.
  • 80% sec .butanol-20% n.butanol 80/20 sec/nor C,
  • Example 2 has been finally repeated by replacing meth yl Cellosolve with n-butyl Cellosolve, ethyl Cellosolve, and 80/20 and 60/40 isoC_ and nC mixtures, formals being obtained with yields and purity levels as of Example 2.
  • CFPP Low-temperature fi Iterabi lity characteristics.
