  • 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.

  • Patent number: 9932293
    Abstract: This invention relates to an etheramine of formula (I) based on glycerine or trimethylolpropane and its manufacturing process, wherein R=H or ethyl, k=0 or 1 A represents a linear or branched alkylene group having C2-C18 carbon atoms, A may be the same as or different from one another, at least one A represents a linear or branched C4-alkylene group, the sum of x, y and z lies in the range of 3 to 100, x?y?1 and z?1, Z=NH2 or OH but at least two Z per molecule are NH2.
