20140105994 | Microencapsulated Amino Acid Composition and the Method of Manufacturing the Microencapsulated Amino Acid Composition - The invention relates to a microencapsulated amino acid composition and methods of manufacturing this composition. Amino acids, such as branched-chain amino acids, have low water solubility, poor hydrophilicity, and poor stability. Amino acids are thus difficult to be digested and absorbed. Consequently amino acids can hardly meet human needs of consuming. This microencapsulated amino acid composition that can quickly disperse and dissolve in cold water, resulting clear solution. The method includes (1) adding coating agents, wetting agents, or other excipients to the amino acid mixture, (2) modifying the surface of microencapsulated particles to considerably accelerate the wetting speed. In this composition, the weight ratio of amino acids and excipients is from 100/0.1 to 100/10.0. | 04-17-2014 |

20110046419 | METHOD FOR PRODUCING ETHYLENE GLYCOL FROM POLYHYDROXY COMPOUND - A method for producing ethylene glycol, including (a) adding a polyhydroxy compound and water to a sealed high-pressure reactor, (b) removing air and introducing hydrogen, and (c) allowing the polyhydroxy compound to react in the presence of a catalyst while stiffing. The catalyst includes a first active ingredient and a second active ingredient. The first active ingredient includes a transition metal of Group 8, 9, or 10 selected from iron, cobalt, nickel, ruthenium, rhodium, palladium, iridium, and platinum, and/or a mixture thereof. The second active ingredient includes a metallic state of molybdenum and/or tungsten, or a carbide, nitride, or phosphide thereof. The method is carried out at a hydrogen pressure of 1-12 MPa, at a temperature of 120-300° C. for not less than 5 min in a one-step catalytic reaction. The efficiency, selectivity, and the yield of ethylene glycol are high. The preparation process is simple and the materials used are renewable. | 02-24-2011 |
20120283487 | METHODS OF USING TUNGSTEN CARBIDE CATALYSTS IN PREPARATION OF ETHYLENE GLYCOL - Tungsten carbide catalysts are used in preparation of ethylene glycol by hydrogenating degradation of cellulose. The catalyst includes tungsten carbide as main catalytic active component, added with small amount of one or more transition metals such as nickel, cobalt, iron, ruthenium, rhodium, palladium, osmium, iridium, platinum, and copper as the second metal, supported on one or more porous complex supports such as active carbon, alumina, silica, titanium dioxide, silicon carbide, zirconium oxide, for conversion of cellulose to ethylene glycol. The catalyst realizes high efficiency, high selectivity, and high yield in the conversion of cellulose to ethylene glycol at the temperature of 120-300° C., hydrogen pressure of 1-10 MPa, and hydrothermal conditions. Compared to the existing industrial synthetic method of ethylene glycol using ethylene as feedstock, the invention has the advantages of using renewable raw material resources, environment friendly process, and excellent atom economy. | 11-08-2012 |
