Novel Zwitterionic Surfactants:Synthesis and Surface Active Properties of N-(3-Alkoxy-2-Hydroxypropyl)-N, N-Dimethyl glycine Betaines
摘要:
Five new zwitterionic surfactants with long chain alkyl betaine structure incorporated with hydroxylpropyl group have been synthesized.Their structures were identified by elemental analysis,IR,1HNMR,and 13CNMR.Surface tension experiments showed that these surfactants have higher surface activity than those without hydroxypropyl group.The values of CMC and γCMC of these surfactants have been determined.
