Surface-active properties of novel cationic surfactants with two alkyl chains and two ammonio groups

A series of bis-quaternary ammonium salts was easily prepared by the reaction of a long-chain tert-alkylamine with epichlorohydrin, and their surface-active properties were measured. The prepared amphipathic compounds had good water solubility and showed characteristic surface-active properties, particularly, extremely excellent foaming ability and foam stability for some specific compounds, such as the compound with a dodecyl and a tetradecyl group as the lipophilic chains. Their critical micelle concentration, which decreased with increased alkyl chainlength, is two orders of magnitude lower compared with the conventional mono-quaternary ammonium salts. In comparison with surface-active properties of bis-quaternary ammonium salts, prepared from various organic dichlorides, there are little differences based on the kind of connecting group in the surface-active properties except for foaming.

METHOD FOR PRODUCING TERTIARY AMINE

The present invention provides a method for producing a tertiary amine by using a secondary amine and an alcohol as starting materials to obtain a corresponding tertiary amine. The method of the present invention includes reacting a secondary amine with an alcohol in the presence of a catalyst, wherein the catalyst is previously used in the reaction of a primary amine with an alcohol to obtain a tertiary amine.

PROCESS FOR PRODUCING NITROGEN-CONTAINING COMPOUNDS

The present invention relates to a process for producing a tertiary amine by reducing an amide compound in the presence of a catalyst containing a sponge copper catalyst obtained by leaching alloy particles containing copper and aluminum and drying the thus leached alloy particles. The present invention provides a process for producing high-purity aliphatic tertiary amines containing a less amount of by-products at a high yield by subjecting aliphatic acid amides to hydrogenation reduction under solvent-free moderate conditions.
