  • the present invention relates to an improved process for the preparation of detergent-dispersant metal additives of high alkalinity, in particular for lubricating oils.
  • the Applicant has found an improved process for obtaining metallic detergent-dispersant additives with TBN (Total Basic Number Standard ASTM D 2896) greater than 200, in a simple and rapid manner, in the absence of excess sulfur. and without the essential presence of heavy monoalcohol.
  • TBN Total Basic Number Standard ASTM D 2896
  • the sulfurization step is preferably carried out at a temperature between 120 and 180 ° C; it can optionally be completed at a higher temperature between 130 and 185 ° C., preferably at a pressure less than or equal to atmospheric pressure.
  • the carbonation operation is preferably carried out at a temperature between 100 and 185 ° C using an amount of C0 2 substantially equal to that which can be completely absorbed.
  • alkylphenols which can be used to carry out the process which is the subject of the invention, mention may preferably be made of those carrying one or more C 9 -C 15 alkyl substituents, and very particularly nonyl, decyl, dodecyl or tetradecylphenols.
  • alkylbenzene sulfonate any solution containing 40 to 95% by weight, preferably 55 to 85% by weight of an alkylbenzene sulfonate in a dilution oil, which may or may not be the same as that used to carry out the process subject of the invention.
  • alkylbenzene sulfonates which can be used, there may be mentioned the salts of sulfonic acids (of molecular weight preferably greater than 400) obtained by sulfonation of petroleum or synthetic fractions obtained by sulfonation of alkylbenzenes derived from olefins or polymers C 1 -C 3 olefins and alkaline earth metals such as calcium or magnesium.
  • the alkaline earth compound used consists of lime and / or magnesium hydroxide or oxide.
  • magnesium oxide any type of magnesium oxide can be used, however, "active" magnesium oxide is preferred.
  • active magnesium oxide denotes magnesium oxide MgO with a specific surface greater than or equal to 80 m 2 / g, for example between 100 and 170 m 2 / g.
  • magnesium oxide MgO with a specific surface greater than or equal to 80 m 2 / g, for example between 100 and 170 m 2 / g.
  • Maglite DE with a specific surface area close to 140 m 2 / g sold by Merck
  • the "Ferumag” with a specific surface area close to 160 m 2 / g and marketed by RHONE-POULENC INDUSTRIES.
  • the metal from which the alkaline earth alkylbenzene sulfonate is derived may or may not be the same as that or those contained in the alkaline earth compound.
  • alkali metal hydroxides which can be used, mention may be made of sodium, lithium and potassium hydroxides.
  • the amount of dilution oil that can be used is such that the amount of oil contained in the final product (including that from the starting alkylbenzene sulfonate) represents from 20 to 60% by weight of said product and of preferably 25 to 55% of said product.
  • a variant of the process which is the subject of the invention consists in preparing "in situ" before the sulfurization-neutralization step, the alkaline earth metal alkyl benzene sulfonate by the action of an oxide or hydroxide of said alkali metal. earthy on an alkylbenzene sulfonic acid as defined above in the presence of oil and optionally alkylene glycol, at a temperature between 40 and 110 ° C, the amount of oxide or hydroxide of alkaline earth metal and of oil to be used being such that the alkylbenzene sulfonate obtained has a TBN less than or equal to 150, preferably less than or equal to 50.
  • the process which is the subject of the invention is very particularly advantageous for preparing detergent-dispersants with a TBN greater than or equal to 250 and having a large percentage by weight of calcium (at least 10%).
  • the process which is the subject of the invention is also advantageous for preparing detergent-dispersants with a TBN greater than 200 and containing at least 2% by weight of magnesium and optionally at least 0.5% by weight of. calcium.
  • the present invention also relates to detergents-dispersants of high alkalinity obtained by the process described above. These have the advantage of good compatibility with viscous oils and a very low rate of sediment. They can be added to lubricating oils in amounts depending on the TBN of said detergent-dispersants, and depending on the future use of said oils; thus for a gasoline engine oil, the amount of detergent-dispersants of TBN between 200 and 300 for example to be added is generally between 1 and 3.5%; for a diesel engine oil it is generally between 1.8 and 5%; for marine engine oil this can be up to 25%.
  • the lubricating oils which can thus be improved can be chosen from a wide variety of lubricating oils, such as lubricating oils of naphthenic base, of paraffinic base, and of mixed base, of other hydrocarbon lubricants, for example lubricating oils derived from coal products, and synthetic oils, for example alkylene polymers, alkylene oxide type polymers and their derivatives, including alkylene oxide polymers prepared by polymerizing alkylene oxide in the presence of water or alcohols, for example ethyl alcohol, the esters of dicarboxylic acids of the liquid esters of phosphorus acids, of alkylbenzenes and of dialkylbenzenes of polyphenyls, of alkyl biphenyl ethers, of polymers of silicon.
  • lubricating oils such as lubricating oils of naphthenic base, of paraffinic base, and of mixed base, of other hydrocarbon lubricants, for example lubricating oils derived from coal products, and synthetic oils, for example
  • Additional additives may also be present in said lubricating oils alongside the detergent-dispersants obtained according to the process of the invention; include, for example, anti-oxidant, anti-corrosion additives, ashless dispersant additives, etc.
  • a carbonation operation is carried out using carbon dioxide at 165-170 ° C at atmospheric pressure until the absorption of CO 2 has ended; this hard phase about 1 hour 30 minutes; the viscosity of the medium drops rapidly at the start of this phase and then stabilizes.
  • the medium is brought to a temperature of 184 ° C. under 20 mm of mercury for one hour.
  • the medium is filtered to remove the sediments and a solution is recovered in 100 N oil of over-alkalized detergent-dispersant, which is degassed and the characteristics of which appear in Table 1.
  • the operation lasted a total of 10 hours.
  • Example 1 to 4 The operations described in Examples 1 to 4 are carried out under the same conditions from a 60% solution in 100 N oil of a calcium alkylbenzene sulfonate, with a molecular mass of approximately 470, solution containing 3.4 % calcium and having a TBN of around 45.
  • Examples 1 to 4 are carried out under the same conditions from an 80% solution in 100 N oil of a calcium alkylbenzene sulfonate, with a molecular mass of approximately 470, solution containing 3.37 % of calcium with a TBN of 33.
