PROCESS FOR MANUFACTURING ALKYLENEAMINE COMPOUNDS
-
Paragraph 0109; 0114-0115, (2021/09/11)
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. The formula I is represented herein.

METHOD FOR PRODUCING POLYETHYLENE POLYAMINES
-
Paragraph 0051-0052; 0060, (2018/02/27)
PROBLEM TO BE SOLVED: To provide a method for producing polyethylene polyamines with high selectivity and high yield. SOLUTION: In the presence of a solid acid catalyst, ethylene amines and aziridine are reacted with each other so that an equivalent of ethylene amines is 3 equivalents or more and 30 equivalents or less relative to aziridine.

Decolorization of polyalkylene polyamines
-
, (2008/06/13)
A process for decolorizing polyalkylene polyamines, which comprises contacting one or more polyalkylene polyamines having an average molecular weight of greater than about 200 and less than about 1000 with carbon at a temperature greater than or equal to about 100° C. and less than or equal to about 300° C. under conditions effective to reduce the color rating of the one or more polyalkylene polyamines.
Process for the dyeing of leather with anionic dyes and polyaminoamide resin as dyeing auxiliary
-
, (2008/06/13)
To improve the affinity of anionic dyestuffs in the dyeing of leather materials, polycondensation products consisting of at least one amine of the formula STR1 in which the radicals have the meanings mentioned in the description with one dicarboxylic acid and, if desired, ω-aminocarboxylic acid or its lactam are highly suitable.
NUCLEOPHILIC CLEAVAGE AND FORMATION OF SATURATED HETEROCYCLES. IX. KINETICS OF THE AMINATION OF 1-AZIRIDINE

1.Enlarging the aminoethyl substituent at the heteroatom of the aziridine ring results in a decrease in reactivity and an increase in substrate selectivity towards nucleophilic cleavage by amines. 2.The reactivity of amines in the nucleophilic cleavage of 1-aziridine is largely governed by the steric accessibility of the nitrogen atoms of the nucleophile.Amino groups in which the environment of the reaction site is the same have similar reactivities.
