564487

Abstract:

A process for the preparation of secondary methylalkyl amines is disclosed, said process comprising reacting, at elevated temperature and pressure, a hexahydrotriazine compound in the liquid state with hydrogen in the presence of a catalyst material having at least one catalytically active metal, said hexahydrotriazine compound having the formula ##STR1## wherein R. sub. 1, R. sub. 2, and R. sub. 3 are, independently, straight or branched, saturated or unsaturated, linear or cyclic hydrocarbon groups or straight or branched, saturated or unsaturated, linear or cyclic hydrocarbon groups wherein one or more CH. sub. 2 groups are replaced by an oxygen atom or a tertiary amine group, provided that any unsaturated group is separated from nitrogen in the hexahydrotriazine ring by at least one carbon atom, any said oxygen atom is enclosed by two carbon groups and any said oxygen atoms and any said amine groups are separated from other oxygen atoms and other amine groups and from the nitrogen in the hexahydrotriazine ring by at least two carbon atoms.

Abstract:

A fabric softener composition comprising a stable, clear single phase solution of an anionic surfactant having an alkyl radical containing at least eight carbon atoms, a cationic surfactant, water and an effective amount of propylene glycol and an alkali metal salt of benzene, toluene or xylene sulfonate. The fabric softener may be highly concentrated and has the property that when added to a detergent solution it imparts a fabric softening effect but does not lessen the detergency of the solution.
