Novel biodegradable and chemically recyclable carbonate-type cationic surfactants consisting of a long chain alkyl group and a quaternary ammonium propyl group were designed and synthesized as a green surfactant. These carbonate-type cationics showed better surface activities in an aqueous solution when compared to the conventional cationics. Novel cationics containing both the carbonate linkage and n-dodecyl group showed strong antimicrobial properties, enzymatic degradabilities for chemical recycling and rapid biodegradabilities by activated sludge.
设计并合成了一种由长链烷基和季铵丙基组成的新型可生物降解且可化学回收的碳酸酯型阳离子表面活性剂，作为绿色表面活性剂。与传统阳离子表面活性剂相比，这些碳酸酯型阳离子表面活性剂在水溶液中表现出更好的表面活性。含有碳酸酯键和正十二烷基的新型阳离子表面活性剂具有很强的抗菌性能、化学回收的酶降解性以及活性污泥的快速生物降解性。
