| 20150299114 | Cyclic process for the production of taurine from alkali isethionate and alkali vinyl sulfonate - The present invention discloses a cyclic process for the production of taurine from alkali isethionate and alkali vinyl sulfonate in a high overall yield of greater than 95% by continuously converting the byproducts of the ammonolysis reaction, sodium ditaurinate and sodium tritaurinate, to sodium taurinate. Sodium sulfate and residual taurine in the crystallization mother liquor are efficiently separated by converting taurine into a highly soluble form of sodium taurinate or ammonium taurinate while selectively crystallizing sodium sulfate. | 10-22-2015 |
| 20160158168 | METHODS FOR THE BIOSYNTHESIS OF TAURINE OR HYPOTAURINE IN CELLS - The present invention describes an approach to increase taurine or hypotaurine production in prokaryotes. More particularly, the invention relates to genetic transformation of organisms with genes that encode proteins that catalyze the conversion of cysteine to taurine, methionine to taurine, cysteamine to taurine, or alanine to taurine. The invention describes methods for the use of polynucleotides that encode cysteine dioxygenase (CDO) and sulfinoalanine decarboxylase (SAD) polypeptides in prokaryotes to increase taurine, hypotaurine or taurine precursor production. The preferred embodiment of the invention is in plants but other organisms may be used. Increased taurine production in prokaryotes could be used as nutraceutical, pharmaceutical, or therapeutic compounds or as a supplement in animal feed. | 06-09-2016 |

| 20100274048 | 2-ACRYLAMIDE-2-METHYLPROPANESULFONIC ACID AND PROCESS FOR PRODUCING THE SAME - A process for producing 2-acrylamide-2-methyl propane sulfonic acid (ATBS) which comprises reacting acrylonitrile, fuming sulfuric acid, and isobutylene. During the reaction, the concentration of 2-methyl-2-propenyl-1-sulfonic acid (IBSA) and/or that of 2-methylidene-1,3-propylenedisulfonic acid (IBDSA) in the reaction system are determined. When the IBSA concentration exceeds 12,000 mass ppm and/or the IBDSA concentration exceeds 6,000 mass ppm, then the concentration of sulfur trioxide in the reaction system is reduced. Thus, ATBS having an IBSA content of 100 mass ppm or lower and an IBDSA content of 100 mass ppm or lower is produced. | 10-28-2010 |
| 20130137893 | PROCESS FOR PREPARING AND PURIFYING SALTS OF ACRYLAMIDO-2-METHYLPROPANESULFONIC ACID - A process for preparing salts of acrylamido-2-methylpropanesulfonic acid (A) using the steps of:

| 20160122295 | PREPARATION METHOD OF SOLID ACRYLAMIDEALKYL SULFONATE - The present invention provides a method for preparing a solid acrylamide alkyl sulfonate. Said method comprises: reacting 2-acrylamido-2-methylpropanesulfonic acid and analogs thereof with an alkaline substance in a solvent. The 2-acrylamido-2-methylpropanesulfonic acid and the analogs thereof and the alkaline substance are significant excess with respect to the solvent, so that the amount of the resulting acrylamido alkyl sulfonate exceeds the solubility under the reaction condition. The acrylamido alkyl sulfonate can be continuously generated and directly massively precipitated, and the precipitated solid product, i.e. the product, is collected. The method of the present invention can greatly improve production efficiency of products, save time, reduce cost, and easy to operate by leaving out the re-crystallization step and the like in the prior art. | 05-05-2016 |
| 20160137596 | METHOD FOR PURIFYING ACRYLAMIDE ALKYL SULFONIC ACID - A method for purifying acrylamide alkyl sulfonic acid comprises: (1) making a material A evenly mixed and contacted with a solvent C, an amount of the material A exceeding a solubility of the material A in the solvent C under the condition where the material A is located, therefore the material A is not completely dissolved by the solvent C; (2) keeping the material A even mixed and contacted with the solvent C for at least 5 minutes; (3) performing a solid-liquid separation to obtain a solid, namely, a purified product B with impurities reduced. In the purifying method according to the invention, the material does not need to be completely dissolved, therefore less solvent is used, and the steps of dissolving the material by increasing temperature, separating out by decreasing temperature or removing the solvent are eliminated, so cost is reduced, efficiency is improved, and operations are simplified. | 05-19-2016 |

| 20140051883 | SYNTHESIS OF MOLECULAR SIEVES FOR MODIFYING THE SURFACES OF NANOPARTICLES HAVING AMPHOTERIC IONS, AND APPLICATION THEREOF - The present invention relates to a surface modification method for improving the dispersion of nanoparticles, and to nanoparticles having improved dispersion properties prepared by the method. More particularly, the present invention relates to a method in which amphoteric compounds are bonded to the surfaces of nanoparticles to improve dispersion at the surfaces of nanoparticles. The present invention also relates to nanoparticles using the method. Both anions and cations are formed on the surfaces of the nanoparticles according to the present invention, and therefore the nanoparticles are electrically stable so as to achieve stability in a wide pH range, are stably dispersed in the event of a high concentration of salts, and the non-specific adsorption thereof is reduced. Novel specific substances or sensors having minimized non-specific adsorption may be produced using the nanoparticles of the present invention. | 02-20-2014 |
