탄소수 10∼18 범위에 있는 고급지방산 즉, decanoic acid, dodecanoic acid, tetradecanoic acid, hexadecanoic acid 및 octadecanoic acid 등을 SO_3-dioxane complex로 α-술폰화 한 다음, dodecanol-1에 에틸렌옥사이드를 5몰, 10몰, 20몰씩 부가시켜 제조한 POE 알킬 에테르류와 각각 반응시켜 15종의 올리고머 음이온성 계면활성제를 좋은 수율로 합성하였고, 이들 최종 합성화합물에 대하여 IR, NMR, 원소분석 등 기기분석을 행하여 분리확인하였다.

Anionic oligomer surfactants, dodecyl polyoxyethylene α-sulfo alkanoates, had been synthesized through the esterification of dodecyl polyoxyethylene glycol and α-sulfo alkanoic acid with straight chain alkyl group having from 10 to 18 carbon atoms to good yield. α-sulfo alkanoic acids were obtained by reaction with long chain alkanoic acids and sulfur trioxide-dioxane complex, and dodecyl polyoxyethylene glycols, by addition reaction with dodecyl alcohol and ethylene oxide(addition, 5, 10, 20㏖) respectively. All the synthetic products could be separated by means of the thin layer and column chromatography, and their structure has characterized with IR, ^1HNMR and elemental analysis, respectively.
