Reaction Steps

Employing the procedure of Example I, an amidoamine oxide was prepared from a polymeric fatty acid containing 87% C36 dimer acid and 13% trimer acid. For the reaction 352.2 gms of the polymeric fatty acid (Empol® 1016) was combined with 30 mls xylene, heated to 200° C. under a nitrogen atmosphere and 147.2 gms (20% equivalents excess) dimethylaminopropylamine added over a 2 hour period. Heating was continued at 200° C. while removing water until the acid value was 2.3. The reaction was terminated at that point and the xylene removed by vacuum distillation. One-hundred and seventy grams of the resulting amidoamine product was then dispersed in water (1000 mls) and reacted with 30% hydrogen peroxide (55.5 gms). The amber liquid product (14.5% solids) was slightly less viscous than the product obtained in Example I, possibly due to the lower solids content. Similar results are obtained when a polymeric fatty acid containing 80% C54 trimer acid and 20% C36 dimer acid is employed.
