The marine pollution with the oil spill becomes the big environmental problem. The development of the oil spill treatment agent with good biodegradability has become desired. We have been investigating the preparation and properties of cleavable surfactants which are designed to decompose into non-surface active species under mild conditions. We have mentioned that the cleavable moiety (noncyclic acetal group, 1,3-dioxolane ring or ester) had a positive effect on the various surface-active properties. In this work, double-chain cleavable nonionic surfactants bearing a 1,3-dioxolane ring or ester were prepared from diethyl tartrate. A sucrose was used as hydrophilic group. We clarified that they have good surface-active properties in seawater, and the decomposition function in acid water. The biodegradabilities of these cleavable surfactants after 28 days were more than 60 % by an oxygen consumption method with activated sludge. We evaluated the biodegradation of heavy oil.

石油泄漏造成的海洋污染已成为重大的环境问题。开发具有良好生物降解性的溢油处理剂已成为迫切需要。我们一直在研究可裂解表面活性剂的制备和性质，这些表面活性剂被设计成在温和条件下分解成非表面活性物种。我们已经提到，可裂解部分（非环状缩醛基团，1，3-二氧戊环或酯）对各种表面活性性质具有积极影响。以酒石酸二乙酯为原料，合成了含1，3-二氧戊环或酯的双链可裂解非离子表面活性剂。蔗糖用作亲水基团。阐明了它们在海水中具有良好的表面活性，在酸性水中具有分解功能。用活性污泥耗氧法测定了这些可裂解表面活性剂在28天后的生物降解率均大于60%。评价了稠油的生物降解性。
