Definitions

  • phase alcohols + water is heavier and goes to the bottom of the tank of the automobile; once intaken this causes the engine to stop, damaging it.
  • the present invention refers to a process and to additives to be used in sparing quantities, to allow the use of alcohols, on their own or in blending with HC, without having the above mentioned inconvenience. This will allow the exploitation of the octanicity and low emissions of alcohols in order to formulate alcohol fuels .
  • solubilization will be inhibited if in the water there will be present a compound that will form a hydrogen bond with it, stronger than that of water-alcohol.
  • the phenol will act at low temperatures in which the water tolerance is lower than the mixtures alcohols/HC.
  • the phenol can be dissolved in an opportune solvent that notably lowers the freezing point.
  • the insolubility in water can be the characteristic of the solvent.
  • the solvents that increase the water tolerance of the alcohols can be alcohols superior to butyl alcohol, benzene, toluene, xylene, 4 methylpentane 2-1, cumene , hexane. They can furthermore be considered compounds of synergic action as the organic acetates (of methyl, of ethyl, of isoamyl, of t-butyl, etc.), the methylcyclopentane, the triethylamine , etc.
  • the aniline can be used, or, better still, the N-methylaniline.
  • Such compounds have an effect that is comparable to phenol as regards to the alcoholic phase and/or hydrocarbon phase mentioned.
  • the N-methylaniline has a low freezing point (-57°C) therefore it can be used together with phenol both as a solvent and as a compound of synergic action.
  • the addition to phenol of aniline and/or of N-methylaniline has furthermore the advantage of diminishing the copper corrosion (ASTM D 130) of gasoline.
  • the organic acetates diminish copper corrosion of gasoline too.
  • other phenolic or ammino compounds can be used with particular reference to substituted anilines.
  • the additive formulated as will be described, besides preventing alcohol solubilization has some intrinsic octanic properties. Furthermore, given the anti-oxidant properties of the phenolic and/or anilinic compounds the oxidation stability (induction period) of the fuel will improve notably.
  • NaCl or KC1 dissolved in the fuel by means of alcohol, would in fact become a solution in water if they came into contact with water that was not very inhibited, thus contributing a limited solubilization of the alcohol in a water phase.
  • Such a solution would furthermore have the advantage of "inhibiting" eventual water carry-over present in the nydrocarbon compound of blending.
  • the electrolyte will have to be insoluble in alcohol and/or hydrocarbons.
  • other electrolytes have to be used, illustrative examples that are not limitative of these are:
  • this type of electrolytes can also be used in the storage tank at the production site. Since a certain amount of water is always present in the storage tanks, it is necessary that prior to the storage of the alcohols, or of their mixtures with HC , the tank shoul ⁇ be emptied and totally drained of water that is p r e s e n t .
  • a saturated solution will be prepared or better still an over-saturated in NaCl and/or KC1 (or in other electrolytes soluble or insoluble in alcohol) that will be injected in the tank by means of the draining tube.
  • sea-water can be used.
  • the tank will thus be ready to receive alcohols, on their own or with HC , treated as already described.
  • the maintainance of the saturation of the solution is sufficient to face the eventual water carry ⁇ over present in the blending components.
  • the dosage of the inhibitor in alcohol/HC phase is carried out on the ground of the water present in the tank, maintaining themselves conservative to keep count of eventual water carry-over in the blending components.
  • the fuel maintains its retentive properties with regards to the alcohols in case it should come into contact with water that has been totally untreated.

Abstract

Le procédé décrit empêche la solubilisation dans l'eau d'alcools, à l'état pur ou mélangés à des hydrocarbures, grâce à la présence d'inhibiteurs de formation de liaisons hydrogéne dans la phase alcool et/ou dans la phase hydrocarbure et/ou dans la phase eau, ce qui permet d'exploiter la teneur en octane et les faibles émissions des alcools, pour formuler ainsi un nouveau type d'essence sans plomb.
