Abstract
Use as descaling and lubricating agents of compositions of C1-C2 esters of monocarboxylic acids from C6 to C20, particularly from C8 to C18, the above-mentioned compositions being characterized by containing esters of monocarboxylic saturated acids C12-C16 in quantity from 65% to 94% by weight, preferably from 68% to 90% by weight, compared to the total esters of monocarboxylic acids.
Description
- The present invention concerns the use as descaling and lubricating agents of particular compositions of C1-C2 esters of monocarboxylic acids from C6 to C20, particularly from C8 to C18, with prevalence of esters of monocarboxylic acids from C12 to C16.
- It is well known that in general the mechanicals parts of any machines can operate in the long run in a non-optimal condition or can even get stuck. This is particularly valid for mechanical parts in movement. In most cases, the above-mentioned inconveniences are due to scales developing and accumulating in time. These scales can be of various types, of inorganic nature (i.e. rust, powders) or of carbonaceous nature (i.e. soot, residual hydrocarbons combustion, impurities contained in the alimentation fuel of diesel engines). Deteriorated mechanical parts can be particularly found in various parts of diesel engines, i.e, feed pumps, hydraulic head of diesel alimentation, injector, injector nozzle.
- Therefore it is felt by skilled persons the need to be able to restore rapidly and efficiently the functionality of the above-mentioned mechanical parts, possibly keeping them lubricated at the same time.
- It has been found that these problems can be solved by a particular composition of methyl and/or ethyl esters of monocarboxylic acids.
- According to that, the present invention concerns the use as descaling and lubricating agents of compositions of C1-C2 esters of monocarboxylic acids from C6 to C20 particularly from C8 to C18, the above-mentioned compositions being characterized by containing esters of monocarboxylic saturated acids C12-C16 in quantity from 65% to 94% by weight, preferably from 68% to 90% by weight, compared to the total esters of monocarboxylic acids.
- The compositions of the present invention arc then methyl and/or ethyl esters, preferably methyl, of the above-mentioned monocarboxylic acids.
- Main components of the above-mentioned compositions are methyl and/or ethyl esters of lauric acid (C12), myristic acid (C14) and palmitic acid (C16). Between these three esters, it is usually prevalent the one derived from the lauric acid.
- Other components of the compositions in the present invention are usually esters C1-C2 of monocarboxylic saturated acids C6 (hexanoic acid), C8 (caprylic acid), C10 (capric acid), C18 (stearic acid) and unsaturated acids C18 (oleic acid and linoleic acid), with prevalence of the last ones.
- These composition conditions arc satisfied by the methyl and /or ethyl esters of particular vegetable oils, as Babassu oil, Coconut oil, Palm Kernel oil. The preferred composition of the present invention is constituted by methyl and/or ethyl ester of Babassu oil.
- The table 1 reproduces the composition in % by weight of the three above-mentioned vegetable oils.

- The transesterification reaction is carried out in presence of basic catalysts, preferably chosen between sodium hydroxide, potassium hydroxide, sodium or potassium methylate, sodium or potassium carbonate, mixed carbonates of sodium and methyl, or potassium and methyl. The last ones can be obtained bubbling CO2 in a solution of sodium or potassium chloride dissolved in methanol.
- The transesterification reaction is carried out at the alcohol boiling temperature and the alcohol and catalyst quantities are function of the composition of the vegetable oil to esterify.
- As it will be demonstrated in the experimental part, the used process allows the reaction completeness and then the absence of free fatty acids in the final product. Moreover the synthesized ester is nearly free of free glycerol and alcohol.

The above-mentioned scales can be of different kind, i.e. rust, powders, carbonaceous residuals, asphaltenes, soot.
- The present invention compositions can be used as such or diluted with hydrocarbon diluents as diesel, petrol, naphtha. It is preferable that the above-mentioned diluents will lead to homogeneous mixtures once blended with the present invention compositions. In the case that the esters of the present invention compositions arc used diluted with hydrocarbon diluents, it is preferable that the weight ratio between the esters compositions and the hydrocarbon diluent will not be lower than 5/95 weight/weight, preferably 20/80.
- The present invention compositions work placing the scaled parts in contact with the present invention compositions (as such or diluted) for the time necessary to restore the functionality of the above-mentioned mechanical parts. Obviously, this time will be function of the scales quantity and type and of the dilution degree of the present invention composition.
- Finally the present invention compositions can be added to the feed oil of diesel engines, particularly with the purpose of cleaning the injectors and the feeding system. In this case, the ester composition of the present invention will preferably be contained in a quantity of at least 0.05% by weight, more preferably of at least 0.1% by weight compared with the diesel oil weight.
- The following examples are reported for a better comprehension of the present invention.
- Example 1 refers to a typical esterification of the Babassu oil, while examples 2-6 refer to applications of the esterified product obtained in the example 1.
- In a 500ml coated reactor, equipped with a bubble cooler, temperature drill and magnetic stirrer, gr 260 of refined Babassu oil are loaded; then a solution of gr 80 of soda dissolved in gr 110 of methanol is added.
- The system is brought at 64°C and is kept under agitation for 1 hour.
- During the reaction, the temperature decreases slightly (62-63°) as the methanol reacts.
- After one hour, the agitation is stopped and it is left to decant.
- The lower part is left in the reactor, the upper part containing the esters, part of the methanol, the catalyst and also a glycerine quote is submitted to 60° C water extraction.
- The hydrophilic part contains glycerine, water, methanol and catalyst.
- The hydrophobic part contains esters, traces of methanol and water.
- The methanol is stripped under vacuum and then recuperated.
- Analyses show absence of starting acids.
- A composition of methyl esters is obtained, whose characteristics fall in the range reported in table 2.
- Object: BOSH C 0681200502 EFEP 60 H 952. Pumping tool, of manual use for verifying the injectors good functioning.
- Problem: The pump kept on jamming, despite the repeated maintenance interventions, during which it was dismantled, washed with diesel and petrol and lubricated with motor car oil Esso 10/40. Unfortunately, 2 weeks without use were enough to find it again blocked.
- Solution: The tool has been dismantled, cleaned and lubricated with the product of example 1 and since then it has not needed maintenance works and always worked well. Two years have nearly passed from that..
- Object: Hydraulic head of ZEXEL diesel pump
- Problem: The pump piston presented difficulties in sliding.
- It has already been done a washing treatment with diesel and petrol and then the pump was lubricated with motor oil Esso 10/40, but the head was newly blocked after a couple of hours being left unused. It has been tested even a specific additive of Winn's(R) brand, "Diesel Power 3", without valuable results. Before testing our product, the mechanic showed that he could not displace the piston neither with a plier help.
- Solution: Some drops of the product of example 1 have been placed on the piston in the point where it looked blocked and immediately with only one finger pressure, the piston moved until the stroke end. From that moment it has been possible to let it glide to and from without the least friction-taking place. The pump had been left exposed in the garage at air and dust for two months without the piston fluency suffering any limitations in time.
- Object: Diesel pump ZEXEL
- Problem: The pump was kept accelerated because of fluency difficulties of its slider.
- Solution: It has been prepared a mixture of 2 litres of diesel and 500 ml of the product of example 1. Only the entrance and exit tubes of the pump had been removed and their openings had been submerged in a vessel containing the mixture. The pump had been set in motion and maintained in function in order to keep the mixture circulating in its inside for 1 hour. The washing and the lubricating done in this way had restored the perfect functioning to the pump, without being necessary to remove and dismantle it.
- The interventions previously realized consisted in removing and dismantling the pump, then it was washed with diesel and petrol and tried to introduce in the fluency slits of the critical points one of the finest and thinnest sandpaper in order to attempt to remove as much as possible of the scales; at the end the pump was washed again with diesel and petrol and lubricated with motor oil Esso 10/40. Although the intervention complexity and care, the functioning never resulted completely recovered. Attempts were made also using specific products Winn's(R), with even more disappointing results.
- Object: DELPHI injector mounted on Micra DCI Common Rail.
- Problem: Nozzle micro holes completely obstructed.
- Solution: The nozzle has been removed and completely submerged in about 10 ml of the product in object. Recovered and dried after some hours, the nozzle resulted completely cleaned from scales and the micro holes resulted completely descaled. Before the use of the product in object there were no solution known able to recover the part that was substituted with a new one.
- Object: Automotive vehicle Terrano II
- Problem: The car misfired and emitted smoke from the exhaust pipes.
- Solution: 500 ml of the product in object had been poured into the tank in addition to diesel, before putting back into circulation the car. At its return to the garage, after a distance covered of about 100 km, the engine resulted perfectly functioning and the exhausting normalized. The use of the Winn's(R) "Diesel Power 3" additive has not given clear results and then it would have been necessary remove the injection system in order to dismantle it, wash it with diesel and petrol and lubricate it with motor oil Esso 10/40, thus obtaining a functioning recover not comparable with that one obtainable with the product in object which results as the only mean able to give back to the system its entire restoration.
