A method of making a solid triamine composition comprising:
- mixing a triamine and an acid, wherein the acid is a monoacid and/or a diacid, wherein the triamine has the following formula:
- wherein R is a straight chain C1-C12 alkyl group, and wherein the ratio of the acid to the triamine is from about 1:10 to about 1:1;
- and
- at least partially neutralizing the triamine to a pH of about 6 to about 11 to form a solid amine salt;
- wherein the method forms a solid composition at a temperature between about 70° F. (21° C.) and 130° F. (55° C.) without requiring casting, extrusion, or cooling step;
- wherein the monoacid has the formula R—COOH,
- wherein R is a branched or linear C4-C20 alkane or alkene, and wherein the diacid is selected from the group consisting of the structure of (a), (b), (c) and combinations thereof, as shown:
- wherein:
- n=1-20,
- R1 is H, C1-C8 alkyl or COOH,
- R2 is H, C1-C8 alkyl, NH2, OH, or COOH, and
- R1 and R2 substitution occurs on at least one carbon within C1-C20 chain;
- R1 and R2 are each COOH;
- R3, R4, R5 and R6 independently are H, C1-C8 alkyl, OH, or NH2
- R1 and R3 are each COOH;
- R2, R4, R5 and R6 independently are H, C1-C8 alkyl, OH, or NH2
- R1 and R4 are each COOH;
- R2, R3, R5 and R6 independently are H, C1-C8 alkyl, OH, or NH2
- R1 and R5 are each COOH;
- R2, R3, R4 and R6 independently are H, C1-C8 alkyl, OH, or NH2 or
- R1 and R6 are each COOH;
- R2, R3, R4 and R5 independently are H, C1-C8 alkyl, OH, or NH2;
- R1 and R2 are each COOH;
- R3, R4, and R5 independently are H, C1-C8 alkyl, OH, or NH2:
- R1 and R3 are each COOH;
- R2, R4, and R5 independently are H, C1-C8 alkyl, OH, or NH2
- R1 and R4 are each COOH;
- R2, R3, and R5 independently are H, C1-C8 alkyl, OH, or NH2;
- R1 and R5 are each COOH;
- R2, R3, and R4 independently are H, C1-C8 alkyl, OH, or NH2.
