Definitions

• the present invention relates to a method of manufacturing a lubricating grease from oil, especially from sunflower oil.
• the invention also covers the fat obtained.
• Industrial lubricating greases are currently obtained from 12-hydroxystearic acid by a saponification reaction in the presence of an alkali metal hydroxide selected from lithium, calcium or aluminum, to name but a few.
• 12-hydroxystearic acid obtained from castor oil, is its high number of carbons in its hydrocarbon chain and the presence of a hydroxyl group on the carbon 12 of the hydrocarbon chain, which leads to additional interactions by hydrogen bonds, at the level of soap fibers obtained which cause the formation of a gel.
• vegetable oil is intended to mean any extract of oleaginous plant seeds, derivatives such as fatty acids, fatty acid esters, whatever the viscosity, the purity and the chemical composition.
• the object of the present invention is to find another vegetable oil and a method for obtaining a fat from this new vegetable oil, capable of substituting for acids 12 derived from castor oil.
• sunflower oil there is a variety called "sunflower classic” whose seeds provide an oil rich in linoleic acid (C18: 2). This variety is widely spread.
• Oleic sunflower varieties now exist on the market whose seeds contain an oil rich in oleic acid 75% to 90% oleic acid (C18: 1).
• Oleic acid is a fatty acid of 18 carbon atoms with a double bond in the 9-position.
• oleic sunflower oil available from large oil suppliers having an oleic acid content of 75 to 85%.
• the first step is the transformation of the sunflower oil to obtain an intermediate product capable of being associated with an oil-based matrix in order to obtain a fat having satisfactory properties, by the saponification reaction in the presence of a neutralizing base. .
• the present invention provides for producing an intermediate product by subjecting the retained vegetable oil to an epoxidation reaction.
• the two vegetable oils used have, before epoxidation, the following fatty acid compositions: Fatty acids Oleic sunflower oil Classic Sunflower Oil Oleic acid 79.16% 27.77% Linoleic acid 11.41% 60.14% Other * 9.43% 12.09% other fatty acids are for example: palmitic acid, stearic acid, linolenic acid, arachidic acid, acosenoic acid or behenic acid.
• a first means for epoxidation is to use a peracid such as performic or peracetic acid, obtained from the corresponding acid, treated with hydrogen peroxide.
• the four intermediate compounds according to the invention show that the epoxidized fatty acids of conventional sunflower oil C and the epoxidized fatty acids of oleic sunflower oil D have parameters close to those of 12-hydroxystearic acid. whose acid, saponification and iodine values are respectively 175 mg of KOH / g, 180 to 190 mg of KOH / g and 5 g of I 2 / 100g
• the four intermediate compounds according to the invention are tested for the manufacture of a fat by a saponification reaction according to a given manufacturing process.
• This process consists in using a matrix composed of oil of petroleum, vegetable or synthetic origin.
• the example used requires about 90% for the matrix, 8% of one of the four intermediate products according to the invention A, B, C or D and 2% of a neutralizing base chosen from hydroxides. calcium or sodium, but in this case it is chosen lithium hydroxide LiOH about 2%.
• a fat is produced under the same conditions with 12-hydroxystearic acid as intermediate product.
• Part of the matrix is introduced into a cooker and then is added the amount of intermediate compound A, B, C or D according to the invention or the amount of control 12 hydroxystearic acid, with stirring with appropriate temperature rise.
• the neutralizing base is introduced into the mixture so as to form a soap.
• the reaction with acid 12 is as follows: CH 3 - (CH 2 ) 5 -CHOH- (CH 2 ) 10 -COOH + LiOH ⁇ CH 3 - (CH 2 ) 5 -CHOH- (CH 2 ) 10 -COOLi + H 2 O
• the soap has a creamy and smooth texture with a drop point greater than 190 ° C.
• the penetration measurements are of the order of 280 tenths of a millimeter.
• the saponification reaction does not seem to occur and especially the resulting mixture has crystals that makes it unusable industrially as a lubricant.
• the measured drop points of the order of 210 ° C are higher than that of the control fat.
• compound B makes it possible to reach stable penetration measurements of the order of 280 tenths of millimeters. Static test behavior is therefore better.
• This compound B oleic sunflower oil epoxidized, can be used as an intermediate product to allow the formation of a fat since the qualities of the fat obtained are greater than that of the control fat.
• sunflower oil can be replaced by oil from other oleaginous varieties such as rapeseed or soy or a combination thereof .
• the fats obtained by saponification of a matrix in the presence of a neutralizing base and of an intermediate compound obtained by hydroxylation of soybean oil makes it possible to achieve results comparable to those obtained with sunflower oil.
