  • Patent number: 6211139
    Abstract: A composition comprising: (a) a compound of the following structural formula: wherein each of R* and R** is independently a linear, branched or cyclic alkylene group containing 2 to 12 carbon atoms, wherein no two nitrogen atoms are separated by fewer than 2 carbon atoms; each of A1, A2, A3, A4, and A5 is independently a straight or branched alkylene containing 2 to 4 carbon atoms; each of R1, R2, R3, R4, and R5 is independently —H or RAC(O)— wherein RA is straight or branched alkyl or alkenyl containing 7 to 21 carbon atoms and 0 to 4 carbon-carbon double bonds; provided that at least one of R1, R2, R3, R4, or R5 is RAC(O)—; each of Q1, Q2 and Q3 is independently —H, —CH3, —C2H5, —C3H7, —C4H5, benzyl, —CH2COOH, or —CH2COOA−; or, if R* is a —CH2CH2— group, Q1 and Q3 together or Q1 and Q2 together may be a —CH2CH2— group to form a six-membered piperazine ring; or, if R** is a —CH2CH2— group,

  • Patent number: 4967008
    Abstract: The present invention is directed to polyamines represented by the following general structure: ##STR1## where R is an organic group, R' is H or CH.sub.3, andx=0-3Tri, tetra, penta, and hexa amines, accordingly, are disclosed.The method for making the novel polyamines comprises a multi-step reaction that commences in step (a) with the cyanoethylation of a primary amine, R--NH.sub.2, with acrylonitrile under cyanoethylation conditions to form an aminonitrile of the structure R--NH--CH.sub.2 --CH.sub.2 --CN. The aminonitrile in step (b) is methylated by reaction with formic acid and formaldehyde under Leuckart reaction conditions to form a monomethyl aminonitrile of the structure R--N(CH.sub.3)--CH.sub.2 --CH.sub.2 --CN. The monomethyl aminonitrile then in step (c) is reduced, preferably by hydrogenation under hydrogenation conditions, to form a monomethyl diamine of the structure R--N(CH.sub.3)--CH.sub.2 --CH.sub.2 --CH.sub.2 --NH.sub.2.
