本研究探討聚丙二醇構造對分解性 Ortho Ester型界面活性劑性質之影響。 所使用界面活性劑分別由PG、TPG、PPG700、PPG1000 與triethyl orthoformate (TEOF)及polyoxyethylene stearyl ethe為原料反應而得。此系列合成物使用元素分析法、FTIR及1H-NMR確認其構造式。而合成ㄧ系列產物經緩衝溶液所配製而成之pH=4,7,10 (80℃)在酸、中、和鹼溶液分解後，再由FTIR判定其分解後構造變化，並利用表面張力、接觸角、起泡性、乳化性、耐酸鹼性做分解後產物之基本界面性質探討。
結果顯示，所合成產物其在pH=4,7,10；80℃下已分解產物，其皆具有降低表面張力、接觸角、起泡性、乳化性及精練性等之良好界面活性。

This research discusses of polyoxypropylene structure on properties of cleavable ortho ester surfactants. The surfactant have been synthesized by the reaction of propylene glycol(PG)、tripropylene glycol(TPG)
、polypropylene glycol (PPG M.W. =700, 1000)、triethyl orthoformate (TEOF) and polyoxyethylene stearyl ether.
FTIR, 1H-NMR and element analysis have been used to confirm the structure of these compounds. We used buffer solution pH=4,7,10 to observe the degradation of products under acidic, neutral or alkaline conditions. The structure change of these cleavage products was confirmed by FTIR analysis. The fundamental surface activity including surface tension, contact angle, foaming and emulsifying power was studied.
