| 20110028731 | PROCESS FOR THE MANUFACTURE OF NITROPROPANES - Provided is a process for the formation of 2-nitropropane and/or 2,2-dinitropropane by the nitration of propane with dilute nitric acid. | 02-03-2011 |
| 20110028732 | NITRATED HYDROCARBONS, DERIVATIVES, AND PROCESSES FOR THEIR MANUFACTURE - Provided is a process for the formation of nitrated compounds by the nitration of hydrocarbon compounds with dilute nitric acid. Also provided are processes for preparing industrially useful downstream derivatives of the nitrated compounds, as well as novel nitrated compounds and derivatives, and methods of using the derivatives in various applications. | 02-03-2011 |
| 20110092737 | ISOTHERMAL REACTOR FOR HYDROCARBON NITRATION - Disclosed are a process and an apparatus for synthesizing nitroalkanes by reaction of a hydrocarbon feedstock with aqueous nitric acid. By using an isothermal reactor with multiple input ports for aqueous nitric acid, a hydrocarbon feedstock may be sequentially exposed to a plurality of flows of aqueous nitric acid as it flows through the reactor. | 04-21-2011 |
| 20110092748 | Process For Nitroalkane Recovery By Aqueous Phase Recycle To Nitration Reactor - Disclosed are a process and an apparatus for synthesizing nitroalkanes by reaction of a hydrocarbon feedstock with aqueous nitric acid. Energy and capital costs may be reduced by recycling a majority of the aqueous phase back to the reactor. | 04-21-2011 |
| 20110092749 | Process For Downstream Recovery Of Nitroalkane Using Dividing Wall Column - Disclosed are a process and apparatus for synthesizing nitroalkanes by reaction of a hydrocarbon feedstock with aqueous nitric acid. Energy and capital costs may be reduced by using a dividing wall column. | 04-21-2011 |
| 20110092750 | PROCESS FOR THE MANUFACTURE OF NITRATED HYDROCARBONS - Provided is a process for making nitrated hydrocarbons by reacting aqueous nitric acid with a hydrocarbon feedstock and a carboxylic acid under specific reaction conditions. | 04-21-2011 |
| 20110105806 | METHOD FOR ELIMINATING COLOR FORMING IMPURITIES FROM NITRO COMPOUNDS - A method for stabilizing nitro compounds against discoloration. The method comprises reacting nitro compounds containing color-forming impurities with nitric acid, neutralizing and washing the product, and distilling therefrom purified nitro compounds. | 05-05-2011 |
| 20110160496 | HYDROCARBON FEED FLEXIBLE HIGH PRESSURE NITRATION PLANT DESIGN - Disclosed is an apparatus for synthesizing nitroalkanes by reaction of a hydrocarbon feedstock with aqueous nitric acid. The apparatus may be designed such that it can synthesize more than one nitroalkane using the same equipment. | 06-30-2011 |
