Abstract:
THIS INVENTION RELATES TO THE RELATIVELY LOW TEMPERATURE TREATMENT OF HYDROCARBONS WITH NITRIC OIDE (NO) AND OXYGEN TO RPODUCE NITRATES, NITRITES AND KETONES AND OTHER OXIDATION PRODUCTS. THROUGH THE USE OF ALKALINE INHIBITORS SUCH AS ALKALI METAL BICARBONATES, THE PRODUCTION OF KETONES AND OTHER NON-NITROGEN CONTAINING OXIDATION PRODUCTS CAN BE MINIMIZED WHILE THE PRODUCTION OF ITRATES AND NITRIES ARE MAXIMIZED.
Abstract:
The invention relates to a method for the continuous production of nitrobenzene, wherein crude nitrobenzene is first produced from benzene by nitration and is then washed successively in at least one acidic wash, in at least one alkaline wash and in at least one neutral wash, wherein at least one additional wash with an aqueous solution of a potassium salt is inserted between the last alkaline wash and the first neutral wash.
Abstract:
Compounds effective in inhibiting replication of Hepatitis C virus ("HCV") are described. This invention also relates to processes of making such compounds, compositions comprising such compounds, and methods of using such compounds to treat HCV infection.
Abstract:
This application discloses provides a process for the introduction of nitro-group functionality into a compound which contains also a site of unsaturation and/or oxygen functionality by direct (one step) oxidation of an oxime functional group mediated by a molybdenum VI/VII peroxo complex, the process comprising: (a) providing a substrate of Formula I containing an oxime functional group; Chemical formula should be inserted here as it appears on the abstract in paper form. wherein R1 and R2 are selected independently from linear, branched or cyclic alkyl and linear, branched or cyclic alkenyl groups, optionally substituted, with the proviso that at least one of R1 or R2 contains a carbon/carbon double bond; and (b) contacting said substrate of Formula I with a molybdenum oxidation complex, thereby oxidizing said oxime functional group to a nitro functional group to yield the structure of Formula III. Chemical formula should be inserted here as it appears on the abstract in paper form. Where R1 and R2 are as defined above.
Abstract:
Nitroalkanes are selectively formed by contacting, at elevated temperature and pressure and in a homogeneous gas phase, an organic carboxylic acid having from two to ten carbon atoms with N0 2 alone or in the presence of oxygen and/or water.
