| 20080253926 | Device for Carrying Out Chemical Reactions - The invention relates to a device for carrying out exothermal chemical reactions wherein a gas phase is guided across a fixed bed and allowed to react. Said device comprises a housing and an exchangeable unit wherein the reaction takes place. | 10-16-2008 |
| 20080293974 | PROCESS FOR CONTINUOUSLY PREPARING METHYL MERCAPTAN FROM CARBON- AND HYDROGEN-CONTAINING COMPOUNDS - Provided is a process for continuously preparing methyl mercaptan by reacting a reactant mixture comprising solid, liquid and/or gaseous carbon- and/or hydrogen-containing compounds with air or oxygen, and/or water and sulfur. | 11-27-2008 |
| 20090053130 | REACTION VESSEL FOR THE PRODUCTION OF HYDROGEN SULPHIDE - The invention relates to a reaction vessel in which hydrogen sulphide is produced from sulphur and hydrogen, wherein the reaction vessel is partially or completely made up of a material which is resistant to the reaction mixture and its compounds and/or elements and which remains resistant even at high temperatures. | 02-26-2009 |
| 20090076302 | PROCESS FOR PREPARING a-KETO ACIDS AND DERIVATIVES THEREOF - A method for preparing α-keto acids, especially α-ketomethionine, and/or derivatives thereof, whereby an aldehyde is reacted with thiols to give a corresponding dithioacetal, the dithioacetal formed, is reacted with an electrophile in the presence of a strong base, and the resulting α,α-(dithio)carboxylic acid is solvolyzed with acid-catalysis to release thiol and give the α-keto acid or a derivative thereof. Umpolung of aliphatic or aromatic aldehydes is effected by reaction with thiols. | 03-19-2009 |
| 20090162474 | 2-METHYLTHIOETHYL-SUBSTITUTED HETEROCYCLES AS FEED ADDITIVES - A chemical compound of the general formula I or II is useful as feed additive: | 06-25-2009 |
| 20100098801 | PREPARATION AND USE OF METHIONYLMETHIONINE AS FEED ADDITIVE FOR FISH AND CRUSTACEANS - An animal feed mixture containing DL-methionyl-DL-methionine and salts thereof for animals kept in aquacultures is provided. Methods for preparing DL-methionyl-DL-methionine of formula (I) | 04-22-2010 |
| 20100247707 | DIPEPTIDES AS FEED ADDITIVES - The invention relates to feed additives containing dipeptides or salts thereof, in which one amino acid residue of the dipeptide is a DL-methionyl residue and the other amino acid residue of the dipeptide is an amino acid in the L-configuration selected from lysine, threonine, tryptophan, histidine, valine, leucine, isoleucine, phenylalanine, arginine, cysteine and cystine; feed mixtures containing these additives and method of producing the dipeptides. | 09-30-2010 |
| 20110015443 | PROCESS FOR CONTINUOUSLY PREPARING METHYL MERCAPTAN FROM CARBON COMPOUNDS, SULFUR AND HYDROGEN - The invention relates to a process for continuously preparing methyl mercaptan by reacting a mixture comprising carbon compounds with sulfur and hydrogen, wherein the carbon disulfide and hydrogen sulfide compounds which form are subsequently converted to methyl mercaptan. | 01-20-2011 |
