20090326278 | Modified carbon nanoparticles, method for the production thereof and use thereof - The present invention relates to novel carbon nanoparticles, especially to carbon nanoparticles which comprise or consist of carbon nanotubes and have been modified by means of acyl groups, to a novel process with which these modified carbon nanoparticles, especially carbon nanoparticles comprising or consisting of carbon nanotubes, are obtainable, and to the use of the modified carbon nanoparticles, especially carbon nanoparticles comprising or consisting of carbon nanotubes. | 12-31-2009 |
20130190535 | Method for Synthesis of Ketones from Plant Oils - Ketones may be produced in high yields from glycerides of short chain fatty acids by reaction with a carboxylic acid. The reaction is conducted in the presence of a catalyst and under conditions effective for ketonization of decanoate with the carboxylic acid to produce free ketones. Reaction of a glyceride comprising at least one ester of decanoic acid with a carboxylic acid selected from acetic acid and/or propionic acid produces 2-undecanone and/or 3-dodecanone, respectively. Catalysts of the formula Fe | 07-25-2013 |
20130211144 | MULTI-STAGE REACTION FOR MITIGATINGTHE PRESENCE OF UNWANTED CATIONS - Methods for producing organic products that may include the steps of providing a feed stream comprising a first organic salt and a second organic salt to a reactor; reacting the feed stream at a first temperature to convert at least some of the first organic salt to the organic products, wherein reacting the feed stream results in a first product stream comprising the organic products and second organic salt; separating at least a portion of the organic products from the first product stream resulting in a first reduced product stream comprising second organic salt; and reacting the first reduced product stream at a second temperature to convert the second organic salt to a second organic products. | 08-15-2013 |
20130310608 | PROCESS FOR REDUCING EMISSIONS OF VOLATILE ORGANIC COMPOUNDS FROM THE KETONIZATION OF CARBOXYLIC ACIDS - Disclosed is a process for reducing the emission of volatile organic compounds that are produced during the ketonization of carboxylic acids to ketones. The ketonization of carboxylic acids produces a gaseous by-product stream containing carbon dioxide and volatile organic compounds. This gaseous by-product stream can be fed to a direct-fired furnace used to heat the ketonization reaction feed streams where the volatile organic compounds are destroyed by combustion in the furnace. The carbon dioxide stream further acts as a diluent for the fuel to the furnace. | 11-21-2013 |
20140051892 | Process for chemical synthesis from an alkenone made from a halogenated precursor - Process for synthesizing a chemical, in particular an agriculturally or pharmaceutically active compound, including: a first step comprising reacting a carboxylic acid halide with a vinyl ether to prepare a halogenated precursor of an alkenone; a second step comprising eliminating hydrogen halide from such precursor to form an alkenone, preferably by thermolysis under specific conditions; and a third step which uses the formed alkenone as a building block to synthesize the chemical. First step may be done in a liquid reaction medium comprising an alkenone or a halogenated alkenone precursor, or in a liquid reaction medium in turbulent state, specifically by creation of gas bubbles of the carboxylic acid halide herein. Second step may include a flash thermolysis, vacuum thermolysis, thermolysis under stripping with inert gas, and/or a thermolysis at a temperature from >90° C. to 120° C. Third step preferably comprises reacting the alkenone with a nitrogen-containing compound. | 02-20-2014 |
20140171688 | DECARBOXYLATION OF LEVULINIC ACID TO KETONE SOLVENTS - Ketones, specifically Methyl ethyl ketone (“MEK”) and octanedione, may be formed from six carbon sugars. This process involves obtaining a quantity of a six carbon sugar and then reacting the sugar to form levulinic acid and formic acid. The levulinic acid and formic acid are then converted to an alkali metal levulinate and an alkali metal formate (such as, for example, sodium levulinate and sodium formate.) The alkali metal levulinate is placed in an anolyte along with hydrogen gas that is used in an electrolytic cell. The alkali metal levulinate within the anolyte is decarboxylated to form MEK radicals, wherein the MEK radicals react with hydrogen gas to form MEK, or MEK radicals react with each other to form octanedione. The alkali metal formate may also be decarboxylated in the cell, thereby forming hydrogen radicals that react with the MEK radicals to form MEK. | 06-19-2014 |
20150018581 | Simultaneous Production of Base Oil and Fuel Components from Renewable Feedstock - The present invention provides a method for simultaneous production of components suitable for production of base oil and fuel components. In the method a feedstock comprising fatty acids and/or fatty acid esters is entered into a reaction zone and subjected to a ketonisation reaction in the presence of a dual catalyst system. This system is configured to perform a ketonisation reaction and a hydrotreatment reaction, under hydrogen pressure. Subsequently ketones are obtained. | 01-15-2015 |
