Patent number: 10633328
Abstract: This invention relates to polyetheramines based on 1,3-dialcohols, in particular to an etheramine mixture comprising at least 90% by weight, based on the total weight of the etheramine mixture, of anamine of Formula (I) and/or (II), wherein R1-R12 are independently selected from H, alkyl, cycloalkyl, aryl, alkylaryl, or arylalkyl, wherein at least one of R1-R6 and at least one of R7-R12 is different from H, wherein A1-A9 are independently selected from linear or branched alkylenes having 2 to 18 carbon atoms, preferably 2-10 carbon atoms, most preferably 2-5 carbon atoms, wherein Z1-Z4 are independently selected from OH or NH2, wherein at least one of Z1-Z2 and at least one of Z3-Z4 is NH2, and wherein the sum of x+y is in the range of from 2 to 200, wherein x?1 and y?1; and x1+y1 is in the range of from 2 to 200, preferably 2-20, most preferably 2-10, wherein x1?1 and y1?1.

Abstract: Compounds of formula (I) have antibacterial activity: wherein R represents hydrogen or 1, 2 or 3 optional substituents; W is ?C(R1)— or ?N—; R1 is hydrogen or an optional substituent and R2 is hydrogen, methyl, or fluorine; or R1 and R2 taken together are —CH2—, —CH2CH2—, —O—, or, in either orientation, —O—CH2— or —OCH2CH2—; R3 is a radical of formula -(Alk1)m-(Z)p-(Alk2)n-Q wherein m, p and n are independently 0 or 1, provided that at least one of m, p and n is 1, Z is —O—, —S—, —S(O)—, —S(O2)—, —NH—, —N(CH3)—, —N(CH2CH3)—, —C(?O)—, —O—(C?O)—, —C(?O)—O—, or an optionally substituted divalent monocyclic carbocyclic or heterocyclic radical having 3 to 6 ring atoms; or an optionally substituted divalent bicyclic heterocyclic radical having 5 to 10 ring atoms; Alk1 and Alk2 are optionally substituted C1-C6 alkylene, C2-C6 alkenylene, or C2-C6 alkynylene radicals, which may optionally terminate with or be interrupted by —O—, —S—, —S(O)—, —S(O2)—, —NH—, —N(CH3)—, or —N(CH2CH3)—; and Q is hydrogen, halogen, nit
