摘要： This invention relates to a process for the separation of acrylonitrile used in the cyanoethylation of glycols to produce a bis(cyanoethylated) aliphatic glycol from the resulting glycol which is then reduced with hydrogen to produce the corresponding bis(aminopropoxy) alkane. In this process, acrylonitrile or methacrylonitrile is reacted with an aliphatic glycol in stoichiometric excess and the acrylonitrile removed from the cyanoethylated glycol by reaction with aliphatic primary or secondary alcohol prior to effecting the hydrogenation of the cyanoethylated aliphatic glycol in the presence of the acrylonitrile-amine reaction product. The reaction product then can be separated by conventional techniques such as distillation.

摘要： The invention pertains to tertiary amines used as catalysts for the preparation of polyurethane foams prepared via the catalytic reaction of a polyisocyanate with a polyol in the presence of blowing agents, etc. The tertiary amine catalysts are prepared by reacting an olefinic nitrile with aliphatic polyol having at least secondary hydroxyl functionality in a ratio less than stoichiometric for providing cyanoalkylated polyol having residual hydroxyl functionality. The resulting cyanoalkylated polyol then is reacted with a secondary amine under conditions for effective reductive alkylation.The tertiary amine catalysts, because of residual secondary hydroxyl functionality, provide for uniform dispersion within a polyurethane, formulation; they provude for additional or extended pot life in polyurethane formulations at temperature below reaction condition, and they are bound by reaction on cure.

摘要： This invention relates to a process for the coproduction of propanediamines and alkylated aminopropanediamines. The process contemplates an initial cyanoethylation of ammonia under conditions for producing aminopropionitrile and modest levels of iminobispropionitrile. After separation of the iminobispropionitrile from the aminopropionitrile, the process involves the catalytic reductive alkylation of the iminobispropionitrile by reaction with an aldehyde in the presence of hydrogen to form the alkylated iminobispropionitrile followed by the catalytic hydrogenation of the nitrile group in aminopropionnitrile and iminobispropionitrile to the amine.

摘要： This invention relates to a process for removing trinitrocresols and picric acid contaminants from a wastewater stream generated in the production of nitroaromatics, particularly dinitrotoluene, by the mixed acid technique. The process involves contacting the crude dinitrotoluene generated by the mixed acid technique with an alkaline medium to generate an alkaline wash water containing water soluble nitrocresols and picric acid therein. This wastewater then, is separated from the organic component or may be recycled for contact with further quantities of crude dinitrotoluene product from the reactor. When the concentration of the water soluble salts of trinitrocresols and picric acid is of sufficient concentration, the wash water is treated with aqueous acid in sufficient proportion to reduce the pH to a level from 3-4. After pH adjustment, the medium is contacted with hydrogen peroxide and a ferrous ion under conditions to effect oxidation of a substantial portion of the trinitrocresol to carboxylic acid, nitric acid and carbon dioxide.

摘要： A method is provided for denitrifying the aqueous spent acid of mononitration. The nitric acid in the aqueous spent acid is recovered by adiabatically reacting greater than a stoichiometric amount of a mononitroaromatic hydrocarbon with the aqueous spent acid which has been fortified to a nitric acid concentration of at least about 2 wt %. The denitrification method is useful in treating the aqueous spent acid phase from the mononitration stage of a dinitrotoluene process.
