Definitions
- the present invention relates to a composition based on fatty acid methyl esters, derived from castor oil, having a low pour point.
- This composition is useful in particular as a lubricant or to facilitate the stripping of concrete.
- the fatty acid composition varies considerably from one vegetable or animal oil to another, so that each transesterified oil has different properties.
- a particularly useful product is a mixture of fatty acid methyl esters derived from castor oil.
- This product contains predominantly methyl esters of C1-C22 fatty acids, the main ones being methyl linoleate and methyl oleate.
- This product also contains two specific compounds that are generally not found in products derived from other vegetable oils, namely 10-undecylenic acid and methyl ricinoleate.
- This product is in particular marketed by Arkema under the designation Oleris® Esterai A.
- Oleris® Esterai A a disadvantage of this product is that it has a relatively high pour point, around + 6 ° C. (according to ASTM D97). . As a result, the use of the product is difficult in cold weather.
- the invention firstly relates to a composition
- a composition comprising:
- the pour point of the composition being less than or equal to 0 ° C. According to one embodiment, the pour point of the composition is less than or equal to -5 ° C, preferably less than or equal to -9 ° C.
- the mixture of methyl esters of castor oil fatty acids has an iodine number of 100 to 120 g / 100 g and comprises, in mass proportions:
- the composition comprises a mass proportion of pour point depressant additive of 1 to 2%, preferably from 1.2 to 1.8%.
- the pour point depressant additive is an acrylic polymer (preferably according to the general formula presented below) dissolved in an oil, the proportions preferably being from 60 to 100 parts of acrylic polymer. for 15 to 40 parts of oil.
- the oil is a paraffinic distillate.
- the additive has: a viscosity at 100 ° C. according to ASTM D445 of 200 to 500 mm 2 / s, preferably of 300 to 400 mm 2 / s;
- the invention also relates to the use of the above composition as a lubricant, concrete release agent, degreasing agent or cleaning agent.
- the present invention overcomes the disadvantages of the state of the art. It provides more particularly a mixture of fatty acid methyl esters derived from castor oil which can be used in cold weather.
- FIG. 1 represents the kinetics of crystallization of various compositions, estimated by the thickness of the crystal layer formed (in ordinate, in mm) as a function of the temperature (in abscissa, in ° C). Details are in Example 1 below.
- composition according to the invention is obtained by mixing a mixture of fatty acid methyl esters derived from castor oil and a pour point depressant additive.
- the mixture of fatty acid methyl esters derived from castor oil is obtained by transesterification of a castor oil with methanol.
- the transesterification rate of the mixture is not necessarily 100%, which means that the mixture of methyl esters in question may comprise a certain proportion of unesterified fatty acids.
- the mixture of fatty acid methyl esters derived from castor oil is preferably characterized by a pour point according to ASTM D97 of 5 to 8 ° C; and / or an iodine value of 100 to 120 g / 100 g.
- the iodine number can be determined according to ISO 3961.
- the mixture of fatty acid methyl esters in question preferably comprises:
- the pour point depressant additive is selected such that it makes it possible to lower the pour point of the composition according to the invention below 0 ° C. (preferably below -1 ° C. C, or -2 ° C, or -3 ° C, or -4 ° C, or -5 ° C, or -6 ° C, or -7 ° C, or -8 ° C, or -9 ° C, according to ASTM D97).
- This may include an acrylic polymer (which includes acrylic copolymers) dissolved in an oil.
- the relative proportions are preferably from 60 to 100 parts of acrylic polymer for 15 to 40 parts of oil.
- the acrylic polymer is preferably a polyalkylmethacrylate of the general formula:
- n is an integer, which is preferably from 200 to 2000, and each R is independently a C1-C22 alkyl group.
- the oil can for example be obtained by catalytic hydrogenation of a petroleum fraction and comprise predominantly predominantly saturated C15 to C30 hydrocarbons, and have a viscosity of less than 19 cSt at 40 ° C. It can in particular be the oil referenced under the number CAS 64742-55-8.
- the oil can also be obtained by catalytic hydrogenation of a petroleum fraction and comprise predominantly C20 to C30 hydrocarbons, predominantly saturated, and have a viscosity greater than 19 cSt at 40 ° C. It may especially be the oil referenced under the number CAS 64742-54-7.
- the oil can also be obtained from a petroleum fraction, by removing paraffins by crystallization in a solvent and comprising predominantly C20 to C30 hydrocarbons, and have a viscosity of greater than 19 cSt at 40 ° C. It may especially be the oil referenced under the number CAS 64742-65-0.
- the additive has:
- a viscosity at 100 ° C. according to ASTM D445 of 200 to 500 mm 2 / s, preferably of 300 to 400 mm 2 / s; and or
- an acid number according to ASTM D974 less than or equal to 0.6 mg KOH / g, preferably less than or equal to 0.5 mg KOH / g.
- a particularly suitable additive is the product marketed by Evonik under the reference VISCOPLEX® 1 -21 1.
- the additive may be present in the composition in a weight ratio of 0.1 to 5%, and preferably 1 to 2%.
- Preferred ranges of contents are: from 1.0 to 1.1%; from 1, 1 to 1, 2%; from 1, 2 to 1, 3%; from 1, 3 to 1, 4%; from 1.4 to 1.5%; from 1.5 to 1.6%; from 1.6 to 1.7%; from 1.7 to 1.8%; from 1.8 to 1.9%; and from 1.9 to 2.0%.
- a weight content of about 1.5% is particularly suitable.
- the content of acrylic polymer or copolymer in the composition of the invention is preferably from 0.5 to 2%, more preferably from 0.8 to 1.4% (especially from 0.8 to 0.9%). , or from 0.9 to 1.0%, or from 1.0 to 1.1%, or from 1.1 to 1.2%, or from 1.2 to 1.3%, or from 1 to at 1, 4%).
- the composition consists essentially of the mixture of fatty acid methyl esters derived from castor oil and the pour point depressant additive. According to another embodiment, the composition consists of the mixture of fatty acid methyl esters derived from castor oil and the pour point depressant additive.
- Example 1 illustrates the invention without limiting it.
- pour point depressant additives are added at a level of 1 to 2.5% in a mixture of fatty acid methyl esters derived from castor oil marketed under the designation Oleris® Esterai A by Arkema (point d). flow: + 6 ° C).
- the additives used are:
- VISCOPLEX® 1 -180 (Evonik): acrylic copolymer in a content of 40 to 70%, combined with a neutral oil, having a viscosity of 300 mm 2 / s at 100 ° C;
- VISCOPLEX® 1 -255 (Evonik): acrylic copolymer in a content of 15 to 40%, combined with a neutral oil, having a viscosity of 45 mm 2 / s at 100 ° C.
- the VISCOPLEX® 1 -21 1 additive is particularly interesting because it allows the pour point to drop to -9 ° C at a concentration of only 1.5%.
- Curve 1 represents the control composition without additive
- curve 2 represents the composition manufactured with VISCOPLEX® 1 -255
- curve 3 represents the composition manufactured with VISCOPLEX® 1 -180
- curve 4 represents the composition manufactured with VISCOPLEX ® 10-310
- curve 5 represents the composition made with VISCOPLEX® 1 -21 1.
- compositions obtained with VISCOPLEX® 1 -21 1 are the most advantageous in terms of homogeneity and fluidity, for a content of additive remaining moderate (1, 5%).
