  • the present invention relates to a new metal detergent-dispersant additive of high alkalinity for lubricating oils.
  • magnesium alkylbenzenesulfonate denotes any solution containing from 25 to 80% by weight, preferably from 30 to 70% by weight of a magnesium alkylbenzenesulfonate in a dilution oil which may or may not be the same as that implemented to prepare the new additive.
  • magnesium alkylbenzenesulfonates which can be used, mention may be made of the magnesium salts of sulfonic acids obtained by sulfonation of alkylbenzenes derived from olefins or from C 15 -C 30 olefin polymers.
  • 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 magnesium alkylbenzenesulfonate) represents from 20 to 60% by weight of said product, preferably from 25 to 55% and very particularly from 30 to 45% by weight of said product.
  • sulfurized calcium alkylphenate denotes any solution containing from 25 to 70% by weight, preferably from 30 to 55% by weight of a sulfurized calcium alkylphenate in a dilution oil which may or may not be the same. than that used to prepare the new additive.
  • sulfurized calcium alkylphenates which can be used, there may be mentioned: those obtained by the action of lime on a sulfurized alkylphenol preferably carrying one or more C 9 -C 30 alkyl substituents (and preferably Cg-C 22 ), such as nonyl, decyl, dodecyl or sulfurized tetradecylphenols possibly followed by carbonation; those obtained by sulfurization with sulfur of an alkylphenol preferably having one or more C 9 -C 30 alkyl substituents (preferably C 9 -C 22 ) in the presence of lime and glycol, optionally followed by carbonation.
  • a sulfurized calcium alkylphenate characterized by a lime / alkylphenol molar ratio of between 0.2 and 2.5 and preferably between 0.4 and 2, and by a sulfur / alkylphenol molar ratio of between 1.1 and 2.2 and preferably between 1.3 and 1.8.
  • 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.
  • MgO 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 marketed by Merck and“ Ferumag with a specific surface area close to 160 m 2 / g and marketed by Rhône-Poulenc.
  • polyalkyleneamines such as polyethyleneamines and very particularly ethylenediamine
  • etheramines and most particularly tris (3-oxa-6-amino hexyl) amine.
  • the amine used may be present in “milk of magnesia from the start of the carbonation operation or during it.
  • the carbonation operation is favorably carried out at a temperature which can range from 90 to 140 ° C. and preferably from 110 to 140 ° C., in one or more stages with the introduction of “milk of magnesia into the medium containing the magnesium alkylbenzenesulfonate , the sulfurized calcium alkylphenate and the dilution oil in one or more stages, each stage of introduction of "milk of magnesia being followed by a stage of carbonation. Said carbonation operation is carried out until the sediment level stabilizes; this lasts a maximum of 6 hours.
  • a variant of the process making it possible to prepare the new additive consists in preceeding the carbonation operation with a step of precarbonation of the reaction medium consisting of magnesium alkylbenzene sulfonate, sulfurized calcium alkylphenate and oil dilution, in the presence of glycol and possibly sulfur.
  • the new additive which is the subject of the invention has the advantage of being perfectly compatible with viscous oils, of containing a low rate of sediment and of being slightly viscous.
  • the present invention also relates to the use of the new additive to improve the detergent, dispersing and anti-wear properties of lubricating oils.
  • the amount of additive to be used depends on the future use of said oils.
  • the amount of additive to be added is generally between 1 and 3.5%; for a diesel engine oil it is generally between 1.8 and 5%; for a marine engine oil, it can go up to 25%.
  • the lubricating oils which can thus be improved can be chosen from a wide variety of lubricating oils, such as naphthenic, paraffinic and mixed base lubricating oils, other hydrocarbon lubricants, for example lubricating oils derived from products.
  • coal, and synthetic oils for example alkylene polymers, alkylene oxide type polymers and their derivatives, including alkylene oxide polymers prepared by polymerizing alkylene oxide to presence of water or alcohols, for example ethyl alcohol, esters of dicarboxylic acids, liquid esters of phosphorus acids, alkylbenzenes and dialkylbenzenes, polyphenyls, alkylbiphenyl ethers, polymers of silicon.
  • Additional additives may also be present in said lubricating oils alongside the new additive of the invention; include, for example, anti-oxidant, anti-corrosion additives, ashless dispersant additives, etc.
  • the reaction medium is heated for 30 minutes at 110 ° C at atmospheric pressure, then 30 minutes in vacuo so as to distill the reaction water.
  • the mixture is heated to 120 ° C. for 2 hours (1 hour 30 minutes at atmospheric pressure and 30 minutes under a vacuum of 120 10 2 Pa), then the vacuum is broken.
  • Milk of magnesia is prepared in a beaker by mixing, with stirring, active magnesium oxide, glycol and an amine.
  • This milk is divided into three relatively equal fractions.
  • the flask is gradually placed under vacuum (40 10 2 Pa) and then heated for 2 hours at 200 ° C.
  • This test is carried out by adding 10% by weight of product to be tested to a SAE 30 mineral oil, storing the solution obtained for 1 month at 20 ° C. and studying the appearance of the solution as a function of time.
  • the finished product is added to an SAE 50 oil with a paraffinic tendency so as to obtain a solution containing 125 millimoles of calcium + magnesium.
  • the solution is stored for 24 hours and then centrifuged under the following conditions: then measure the sediment rate.
  • Example 2 The operations described in Example 1 are repeated, replacing the 16.5 g of ethylenediamine with 8 g of tris (3-oxa-6-amino-hexyl) amine called "TOA".
  • Example 1 The operations described in Example 1 are repeated, carrying out the start of the carbonation step at 130 ° C. instead of 110 ° C.
  • the mixture is heated to 110 ° C. and 112 g of glycol are charged in 1 hour.
  • the reactor is placed under vacuum.
  • the vacuum is broken, the heating is stopped and carbonated for 1 hour at a rate of 0.5 g / min.
  • a mixture of 129 g of MgO and 349 g of glycol is prepared in a beaker, which mixture is introduced into the reactor over 5 minutes.
  • C0 2 is introduced into the medium. Two hours later, 16.5 g of ethylenediamine are introduced, then two hours more after 85 g of water, then carbonation is continued for a further 2 hours.
  • the medium is distilled for 2 hours at 200 ° C under 40 10 2 Pa.
  • The% of raw sediment is 2.3.
  • Example 12 The operations described in Example 12 are repeated in the absence of ethylenediamine.
