초록

본 연구는 트리에탄올아민형 양이온 계면활성제(TEA-EQ)의 합성과 그 응용에 관한 것으로, 지방산과 트리에탄올아민의 특정 몰비와 반응온도에 따라 트리에탄올형 양이온 계면활성제의 mono, di, tri 구조가 다르게 합성되는 것을 알 수 있었고, 분석은 NMR로 해석하였다. 안정성은 섬유유연제에 적용한 후, 각각 45 ℃에서 4개월간 상안정성을 육안으로 확인하였다. 장기안정성은 Tri-TEA-EQ 함량이 증가할수록 감소하였고 Mono-TEA-EQ 함량이 많을수록 증가하였다. 또한 지방산의 종류에 따른 유연력 및 흡수력을 평가하였는데, 포화지방산이 증가할수록 유연력이 증가하고, 불포화지방산이 많을수록 흡수 력이 증가하는 현상을 보였다. 유연력 평가는 일반 가정용 수건의 터치감을 이용한 관능평가로 실시하였으며 흡수력은 유연제 처리 후 흡수되는 물의 높이로 측정하였다.

Triethanolamine-type cationic surfactants were synthesized and their applications were established. The production of mono-, di-, and tri-TEA-EQ (triethanol-amine-esterquater) were dependent on the molar ratio of fatty acid and triethanolamine under the controlled reaction temperature. The structures were elucidated by H1 NMR. Long-term stability was dependent on the amount of mono- and tri-TEA-EQ. When the amount of mono-TEA-EQ was increased, long-term stability was increased. However, the more tri-TEA-EQ made long-term stability decreased. Softening was dependent on the amount of saturated fatty acid, and re-wettability was counted on the amount of unsaturated fatty acid. Softening was measured by the method of sense estimation e.g. touching to home-towel. Absorption was determined to calculate the height of water on a towel after treatment.
