| 20090099345 | Carbon-Based Solid Acid, Catalyst Comprising the Solid Acid, and Reaction Using the Solid Acid as Catalyst - A carbon-based solid acid which has high activity and high thermal stability and is useful as an acid catalyst for various reactions such as hydration of olefins. | 04-16-2009 |
| 20090137850 | Method for Hydrating Olefins - A novel olefin hydration method is provided for efficiently producing alcohols by hydration of olefins containing 2 to 5 carbon atoms in the presence of a catalyst. Thus, alcohols are produced by hydrating olefins containing 2 to 5 carbon atoms at reaction temperature of 100 to 250° C. in the presence of a solid acid catalyst consisting of carbonaceous materials containing sulfonic acid groups obtained from an organic matter by carbonization and sulfonation. In carrying out this method, the organic matter is preferably an aromatic hydrocarbon or a saccharide, the olefin is preferably propylene or a butenes, and the hydration reaction temperature is not lower than 120° C., more preferably not lower than 150° C. | 05-28-2009 |
| 20100305346 | METHOD FOR PRODUCING FATTY ACID MONOESTERIFIED PRODUCT USING SOLID ACID CATALYST - The present invention provides a method for producing a fatty acid monoester product by reacting an animal oil and/or a vegetable oil with an alcohol in the presence of a sulfonic acid group-introduced amorphous carbon catalyst and water. By this method, the production of a fatty acid monoglyceride, which is difficult to separate from the fatty acid monoester, can be suppressed, and the fatty acid monoester can be efficiently produced. | 12-02-2010 |

| 20080227996 | Sulfonated Amorphous Carbon, Process for Producing the Same and Use Thereof - An amorphous carbon having sulfonate group introduced therein is provided which is characterized in that chemical shifts of a condensed aromatic carbon 6-membered ring and a condensed aromatic carbon 6-membered ring having sulfonate group bonded thereto are detected in a | 09-18-2008 |
| 20090131709 | Processes for Producing Higher Fatty Acid Esters - As means for producing a biodiesel oil from a feed oil containing a free fatty acid at high efficiency, the following processes (1) to (3) are provided: (1) a process for producing a higher fatty acid ester, comprising reacting a lower alcohol with a higher fatty acid in the presence of an amorphous carbon having a sulfonate group introduced therein, thereby producing the higher fatty acid ester; (2) a process for producing a higher fatty acid ester, comprising reacting a lower alcohol with a higher fatty acid and a higher fatty acid triglyceride in the presence of an amorphous carbon having a sulfonate group introduced therein, thereby producing the higher fatty acid ester by both of the reaction between the lower alcohol and the higher fatty acid and the reaction between the lower alcohol and the higher fatty acid triglyceride; and (3) a process for producing a higher fatty acid ester, comprising: reacting a lower alcohol with a higher fatty acid and a higher fatty acid triglyceride in the presence of an amorphous carbon having a sulfonate group introduced therein, thereby producing the higher fatty acid ester by both of the reaction between the lower alcohol and the higher fatty acid and the reaction between the lower alcohol and the higher fatty acid triglyceride; and reacting the unreacted lower alcohol with the unreacted higher fatty acid triglyceride in the presence of an alkali hydroxide, thereby producing the higher fatty acid ester. | 05-21-2009 |
| 20090176979 | PROCESS FOR PRODUCTION OF POLYSACCHARIDE AND/OR MONOSACCHARIDE BY HYDROLYSIS OF DIFFERENT POLYSACCHARIDE - The object is to produce a polysaccharide and/or a monosaccharide efficiently by hydrolyzing a different polysaccharide efficiently. The hydrolysis of a polysaccharide is an important means for producing a monosaccharide that can be used as a starting material for the production of ethanol, the solubilization of a water-insoluble polysaccharide, and the production of a useful water-soluble low-polymeric saccharide or the like. For achieving the object, a polysaccharide to be hydrolyzed is reacted with water in the presence of a carbonaceous material having sulfonic acid group therein to cause the hydrolysis of the polysaccharide to be hydrolyzed, thereby producing a other polysaccharide and/or a monosaccharide. | 07-09-2009 |
| 20100048835 | SULFONIC ACID GROUP-CONTAINING CARBONACEOUS MATERIAL - A sulfonic acid group-containing carbonaceous material that is useful as a solid acid catalyst for various reactions such as hydration of olefins and acidolysis reaction of hydroperoxide and also useful as a proton conductor material having excellent proton conductivity is provided. In addition, an economical and environmentally friendly method for producing methyl ethyl ketone is provided. A sulfonic acid group-containing carbonaceous material having high catalytic activities for various acid catalyst reactions and also having high proton conductivity can be obtained by carbonization and sulfonation of a phenolic resin. | 02-25-2010 |
| 20100216953 | METHOD FOR PRODUCING SULFONIC ACID GROUP-CONTAINING CARBONACEOUS MATERIAL, SOLID ACID CATALYST, METHOD FOR PRODUCING ALKYLATION REACTION PRODUCT, AND METHOD FOR PRODUCING OLEFIN POLYMER - The method for producing a sulfonic acid group-containing carbonaceous material of the present invention comprises the step of carbonizing and sulfonating a polymer having a structural unit derived from resorcinol by heating in an inert gas atmosphere to obtain a sulfonic acid group-containing carbonaceous material. A catalyst comprising the resulting sulfonic acid group-containing carbonaceous material is useful for producing a target substance with high efficiency in various reactions in hydrophobic media such as alkylation reaction and polymerization reaction of olefins. | 08-26-2010 |
