Characterization and Properties of Series Sulfo-propane Betaines
Wei Ding · Science Technology and Engineering · 2010
Three products of the structures were characterized by FT-IR and 1H NMR spectroscopy,which proved the products are alkyl dimethyl sulfo-butane betaines,and three kinds of sulfo-propane betaines of surface property,foaming property and emulsifying property were studied.The results show that with the increase of alkyl chain length surface properties activity of three kinds of sulfo-propane betaines is gradually improved.As the mass concentration of three kinds of surfactant raised,the foaming power increases firstly and to a certain value essentially unchanged,and foam stability enhances gradually with increasing concentration.As the temperature increased,the foaming power heightenes slowly,while foam stability decreases.
