权利人:TOTALENERGIES ONETECH
摘要:The present invention relates to a method for synthesising an amino spiroboronate compound, comprising: (i) at least one step of reacting at least one hydroxybenzoic acid, optionally substituted with at least one hydrocarbon group, and at least one borated compound; and (ii) at least one step of neutralising the spiroboronate compound obtained at the end of step (i) with at least one amine, step (i) being carried out in the absence of solvent. The invention also relates to a method for preparing a lubricant composition comprising at least one step of mixing the amino spiroboronate compound obtained at the end of the synthesis method with at least one lubricating base oil.

标 题 :Method for the preparation of maleimides

摘要:In accordance with the present invention, there are provided improved methods for the preparation of maleimide monomers. This new method for the synthesis of maleimides is clearly superior to those documented in the prior art. Furthermore, the invention method utilizes materials with reduced toxicity, thus the overall process has a minimal impact on the environment. Thus, in accordance with the present invention, it has been discovered that certain amine salts can be successfully used to replace the polar, aprotic solvents cited in the prior art for the cyclodehydration of maleamic acids. The use of these salts provides competitive reaction times and product yields relative to results obtained with the polar, aprotic solvents. These salts have the advantage of having no vapor pressure and, therefore, have no possibility to co-distill with the water produced by the cyclodehydration reaction. Furthermore, such salts can be tailored to have desirable solubility characteristics (i.e., soluble in the refluxing azeotropic solvent, but insoluble at room temperature) that permit their easy removal from the reaction product. Such salts are not destroyed during the cyclodehydration reaction and, therefore, can be efficiently recycled again and again.

摘要:Novel dissymmetric N,N-dialkylamides which meet the following formula (I): n nwhere R represents a linear or branched alkyl group at C 8 to C 15 . A method for synthesizing these N,N-dialkylamides, and to the uses of same as extractants, alone or in admixture, in order to extract uranium and/or plutonium from an aqueous acid solution, or to totally or separate uranium from plutonium from an aqueous acid solution and, in particular, an aqueous solution resulting from dissolving spent nuclear fuel in nitric acid. Further, a method for processing an aqueous solution resulting from the dissolution of a spent nuclear fuel in nitric acid, allowing the uranium and plutonium contained in the solution to be extracted, separated and decontaminated in a single cycle, without requiring any plutonium reduction operation, and in which one of the aforementioned N,N-dialkylamides or a mixture of same is used as extractant. Applications for the method include the processing of spent nuclear fuels, in particular comprising uranium (e.g. UOX) or uranium and plutonium (e.g. MOX).

摘要:Cyclic amidocarboxy surfactants having general formula (I) wherein: R1 and R2 are independently selected from the group consisting essentially of H or C1-C40 linear or branched, substituted or unsubsituted alkyl, cycloalkyl, alkylene, alkaryl, aryl or R3-O-R4 groups, with R3 and R4 being independently selected from the group consisting essentially of C1-C22 linear or branched, substituted or unsubstituted alkyl, cycloalkyl, alkylene, alkaryl and aryl groups; y is an integer of a value satisfying the valency of M; and M is a cation and is preferably selected from the groups consisting of H, Na, K, NH4 [including (CH3CH2)3NH, (CH3CH2)2NH2, (HOCH2CH2)3NH, (HOCH2CH2)2NH2 and similar ammonium derivatives], Ba, Ca, Mg, Al, Ti, Zr and mixtures thereof. These surfactants are useful in a variety of technical applications, such as fast-break emulsifiers in personal care products; destructible latex polymerization surfactants in manufacture and compounding of various coating or adhesive systems; domestic fabric softening agents; foodstuff emulsifiers; caustic-stabile surfactants; bleach-stabile surfactants; various domestic detergents and hard surface cleaners, emulsifiers for portland cement and concrete; floatation/benefication agents for mining/processing various mineral ores; additives for electroplating and/or surface finishing for metal goods; additives for plaster, gypsum and miscellaneous building materials; enhanced oil recovery additives; wetting and lubricating agents for industrial textile processing; compatibilizers/surfactants for polyurethane/isocyanurate foam systems, wood pulping additives; emulsifiers for various industrial surfactant systems, such as fatty alcohol/water emulsions; pour-point depressants for transporting petroleum crude oils, suspension agents for various particulate materials, such as anti-dandruff materials, i.e., sulfur, zinc pyrithone, etc. and other particulate materials, such as pulverized coal, and other similar uses.
