  • Publication number: 20220348533
    Abstract: The invention relates to a method for the purification of aniline, comprising the following steps: a) providing a raw aniline fraction; b) extracting the raw aniline fraction with an aqueous extractant containing, in relation to the total mass of the aqueous extractant, an alkali metal hydroxide in a concentration range from 0.009 to 2.05 mass % and an alkali metal salt that is different from an alkali metal hydroxide in a concentration range from 2.40 to 25.0 mass %, wherein an organic aniline phase and an aqueous amino phenolate phase are obtained after a phase separation; c) distilling the organic aniline phase from step b), obtaining a flow of purified aniline, a gaseous flow that boils at a lower temperature than aniline and containing organic impurities, and a liquid flow that boils at a higher temperature than aniline and containing organic impurities and aniline.

  • Patent number: 10815189
    Abstract: The invention relates to a method for continuous production of nitrobenzene by means of nitration of benzene with nitric acid and sulfuric acid, in which load change (i.e. a reduction or increase in the quantity of nitric acid supplied to the process per time interval) is particularly advantageously developed. The invention particularly relates to a method in which, in the case of a load reduction, the ratio of the masses of benzene and nitric acid supplied per time interval is significantly increased compared to said ratio before the load change and/or the ratio of the masses of nitric acid and sulfuric acid supplied per time interval is significantly reduced compared to said ratio before the load change. In the event of a load increase, the reverse is carried out.

  • Patent number: 8680064
    Abstract: Short hairpin RNA (shRNA) interference therapy targeting hypoxia inducible factor—lot (HIF-1 ?) prolyl-4-hydroxylase protein (HIF-PHD2) is used for treatment of myocardial ischemia. This treatment can be followed noninvasively by molecular imaging. Provided are compositions comprising novel vectors encoding shRNA targeting the HIF-1? and asparaginyl hydroxylase genes. The vectors encoding shRNA are also useful for the treatment of cardiac diseases, peripheral vascular diseases and decubitis ulcers.
