20110105804 | Process for producing nitroalcohols - Nitroaldol (“Henry”) reactions between nitroalkanes and aldehydes in the presence of a catalyst and a two-phase reaction medium produce nitroalcohols at increased reaction rates compared to single-phase organic solvent systems, and do not require use of surfactants as is typical of single-phase aqueous solvent systems and solventless systems. The reaction medium comprises an organic solvent phase and an aqueous solvent phase. The aqueous solvent may be 100% water. | 05-05-2011 |
20110224460 | PROCESS FOR MAKING AMINOALCOHOL COMPOUNDS - Provided is a process for making an aminoalcohol compound. The process comprises using an excess amount of aliphatic aldehyde in a condensation step between the aldehyde and a nitroalkane, and using an aldehyde scavenger in a reductive hydrogenation step. The process yields aminoalcohol compounds exhibiting reduced color and odor. | 09-15-2011 |
20130172622 | PROCESS FOR MAKING TERTIARY AMINOALCOHOL COMPOUNDS - Provided is a process for making a tertiary aminoalcohol compound. The process comprises using an excess amount of a carbonyl compound in a condensation step between the carbonyl compound and a nitroalkane, and conducting a hydrogenation/alkylation step to produce the tertiary aminoalcohol. The process uses fewer steps than conventional processes. | 07-04-2013 |
20130261148 | PROTECTED ANTIMICROBIAL COMPOUNDS FOR HIGH TEMPERATURE APPLICATIONS - Provided are protected antimicrobial compounds which are useful for controlling microorganisms in aqueous or water-containing systems, such as oil or gas field fluids, at elevated temperature. The antimicrobial compounds are of the formula I: | 10-03-2013 |
20130267604 | PROTECTED ANTIMICROBIAL COMPOUNDS FOR HIGH TEMPERATURE APPLICATIONS - Provided are protected antimicrobial compounds which are useful for controlling microorganisms in aqueous or water-containing systems, such as oil or gas field fluids, at elevated temperature. The antimicrobial compounds are of the formula I: | 10-10-2013 |
20140145108 | PROCESS FOR MAKING TERTIARY AMINOALCOHOL COMPOUNDS - A process for making a tertiary aminoalcohol compound is disclosed. The process comprises using an excess amount of a carbonyl compound in a condensation step between the carbonyl compound and a nitroalkane in the presence of a catalytic amount of a tertiary aminoalcohol compound, and conducting a hydrogenation/alkylation step to produce the tertiary aminoalcohol. The tertiary aminoalcohol compound used to catalyze the condensation step is preferably the same tertiary aminoalcohol compound produced in the hydrogenation/alkylation step. The process uses fewer steps than conventional processes. | 05-29-2014 |
20140200371 | PROCESS FOR THE PREPARATION OF ALKYLDIAMINES - Provided is a process for preparing alkyl diamine compounds in high purity. The process utilizes an alkyl amine compound during the reduction of a nitroamine, resulting in reduction of the concentration of undesired byproducts. | 07-17-2014 |
20150038746 | Process for the Preparation of Nitroalcohols - A process of preparing a nitroalcohol, e.g., 2-nitro-2-methyl-1-propane, from a nitropolyol, e.g., 2-nitro-2 -methyl-1,3-propanediol, the process comprising the step of contacting under hydrogenation conditions the nitropolyol with hydrogen, a hydrogenation catalyst and, optionally, a chelating agent. | 02-05-2015 |
