摘要： The invention pertains to compounds comprising at least one cyclic urea moiety consisting of a head portion and a tail portion connected through an amide moiety or a cyclic amidine moiety, wherein the head portion comprises a polyalkylenepolyamine structure comprising 3 to 10 C2-C4 alkylene moieties present between nitrogen atoms, the nitrogen atom in the amide moiety or cyclic amidine moiety being counted as a nitrogen atom of the polyalkylenepolyamine structure, wherein the alkylene moieties may be the same or different and may be substituted with one or more C1 to C3 alkyl groups, wherein at least one of the alkylene moieties together with its adjoining nitrogen atoms is in the form of a cyclic alkylene urea moiety of the formula (I) wherein A is a C2 to C4 alkylene moiety which may be substituted with one or more C1 to C3 alkyl groups and wherein the tail portion consists of an alkyl or alkenyl group with 6 to 24 carbon atoms which may be substituted. The compounds find use in the prevention of corrosion of a surface susceptible thereto.

摘要： The invention pertains to a process for manufacturing alkyleneamine compounds, comprising the steps of - in a reaction medium reacting an alkyleneurea compound comprising at least one primary amine group, or at least one cyclic secondary amine group, or at least one primary amine group and at least one cyclic secondary amine group, and at least one cyclic alkyleneurea group of formula I wherein A is selected from the group of C2 to C4 alkylene units, optionally substituted by one or more C1 to C3 alkyl groups, with an alkylhalide compound to form an alkyleneamine hydrohalide salt comprising at least one cyclic alkyleneurea group of formula I, the alkylhalide compound being selected from the group of haloalkanes with 2-6 halogen atoms, and haloaminoalkanes, and - reacting the alkyleneamine hydrohalide salt with a base to form an alkyleneamine compound comprising at least one cyclic alkyleneurea group of formula I. In one embodiment the reaction is carried out in the presence of one or more of ammonia and additional alkyleneamine compound. The process according to the invention produces less cyclic and branched side products and more straight-chain higher alkyleneamines than conventional processes, in particular more straight-chain ethyleneamines selected from L-TETA, L-TEPA, and L-PEHA.
