摘要:
This invention provides for the separation of the contents of the process discharge stream of reaction in which an amine is produced from a nitrile. An inorganic base having a concentration greater than 40 weight percent is introduced into the process discharge stream which is decanted, purged, flashed, and a portion thereof recycled.

NOVEL N,N''-BIS-TRIFLUOROMETHYLTETRAFLUOROETHYLENE DIAMINE AS PREPARED BY REACTING TETRACHLOROETHYLENE-1,2-BISISOCYANIDE DICHLORIDE WITH ANHYDROUS HYDROFLUORIC ACID UNTIL HYDROGEN CHLORIDE EVOLUTION CEASES. THIS NOVEL COMPOUND IS USEFUL IN ORANIC SYNTHESIS AND DIRECTLY AS AN INSECTICIDE.
摘要:
Novel fabric conditioning compounds are formed by reacting a higher alkyl-1, 2-epoxide with a lower alkanediamine. The compounds may be incorporated into a laundry product and used in the wash cycle or may be applied in either the wash cycle or the rinse cycle.
摘要:
Novel dibicyclo [3.1.1] and [2.2.1] heptyl and dibicyclo [3.1.1] and [2.2.1] heptenyl polyamines are useful antimicrobial agents, as well as algae inhibitors. They are especially useful as hard surface disinfectants and as additives to oil well drilling muds, injection brines and industrial water where bacterial control is desired.
摘要:
In the production of amines from nitriles where the nitriles are hydrogenated under pressure in the presence of a Raney Nickel Catalyst using hydrogen produced from methane and containing CO.sub.2, a more efficient separation of the product hexamethylene diamine from the catalyst is obtained by maintaining a specified carbonate concentration. This specific carbonate concentration improves the settling characteristics of the catalyst and reduces catalyst carryover into the crude hexamethylene diamine during decantation.
摘要:
In the production of hexamethylenediamine from adiponitrile an inorganic base is used to facilitate separation of Raney nickel catalyst and crude hexamethylenediamine.
摘要:
Novel dibicyclo [3.1.1] and [2.2.1] heptyl and dibicyclo [3.1.1] and [2.2.1] heptenyl polyamines having a cyclohexylene group in the polyamine moiety are useful antimicrobial agents, as well as algae inhibitors. They are especially useful as hard surface disinfectants and as additives to oil well drilling muds, injection brines and industrial waters where microbial control is desired.
