7 results about "Octadecenoic Acid" patented technology

A method to synthesize a silver nanohybrid material. The method includes mixing a nitrate solution with a citrate solution to form silver nanoparticles (AgNPs). The method further includes esterifying a first mixture including octadecanoic acid, octadec-9-enoic acid, and octadeca-9,12-dienoic acid with caffeic acid in the presence of an acid catalyst and a solvent to form an unsaturated carboxylic acid mixture including first, second, and third acrylic acid derivatives. The method includes reacting the unsaturated carboxylic acid mixture with ethylene glycol to form a second mixture including first, second, and third ester derivatives. The method further includes mixing the AgNPs with the second mixture to form a third mixture. The method includes evaporating water from the third mixture to form the silver nanohybrid material. The silver nanohybrid material includes a AgNP core covered with the first, second, and third ester derivatives bonded to the AgNP core.

The present invention relates to an alcoholic beer having an ethanol content of at least 1% ABV and containing 9 (S), 12 (S), 13 (S)-trihydroxy-10 (E)-octadecenoic acid (TOA) and free amino nitrogen (FAN) in a ratio of less than 0.035 mg TOA / mg FAN. The inventors have found that aging of alcohol-containing beer during storage can be retarded by selectively removing 9 (S), 12 (S), 13 (S)-trihydroxy-10 (E)-octadecenoic acid (TOA) from wort prior to fermentation. Another aspect of the invention relates to a method for preparing beer, comprising the following consecutive steps:-providing wort; -contacting the wort with a ZSM-5 zeolite; -separating the treated wort from the ZSM-5 zeolite; -fermenting the treated wort with a yeast to produce a fermented wort having an alcohol content of at least 1% ABV; and-separating the yeast from the fermented wort.

This invention relates to the field of genetic engineering technology, and more particularly to a gene for the biosynthesis of (Z)-13-octadecenoic acid and its application. A gene for the biosynthesis of (Z)-13-octadecenoic acid is provided, the amino acid sequence of which is shown in SEQ ID NO: 1. This invention discovers that expressing a protein with the amino acid sequence shown in SEQ ID NO: 1 in plants in conjunction with a hexadecimal fatty acid-specific thioesterase and a Z11 desaturase can synthesize (Z)-13-octadecenoic acid. The process of synthesizing (Z)-13-octadecenoic acid using plants is green and pollution-free, purification is simple and convenient, environmental pollution is low, and the extraction purity is high.

The invention relates to the technical field of daily chemical industry, in particular to high-activity brushing-free washing powder and a preparation method thereof. The washing powder is prepared from the following raw materials in parts by weight: 1 to 2 parts of anhydrous sodium sulfate, 10 to 15 parts of anhydrous sodium metasilicate, 15 to 20 parts of ethylenediamine tetraacetic acid tetrasodium salt, 3 to 5 parts of lauryl sodium sulfate, 1 to 2 parts of compound protease, 5 to 10 parts of iso-tridecanol polyoxyethylene ether, 6 to 8 parts of cis-9-sodium octadecenoate and 5 to 8 parts of citric acid. According to the washing powder disclosed by the invention, through the synergistic effect of carefully proportioned cis-9-sodium octadecenoate, anhydrous sodium sulfate and compound protease, the decontamination capability and activity of the washing powder are remarkably improved, and the three components are combined to form an efficient compound decontamination system, so that the washing powder can achieve an excellent decontamination effect at low concentration; the requirement for mechanical external force in the washing process is reduced, a user only needs to soak or softly wash, the powerful decontamination effect can be achieved, the user does not need to rub and brush forcefully, and scrubbing-free effect is achieved.
