Abstract:
Som e k inds of fatty a lcohol ether carboxy lates (AEC: C12H25O ( CH2CH2O) nCH2COONa, n = 3, 4, 7, 9) w ere synthesized in wh ich some k inds of fatty alcoho l ether ( AEO: C12H25O ( CH2CH2O ) nH, n= 3, 4, 7, 9) w ere used. The optimum reaction cond it ions w ere determ ined w ith n ( fatty a lcoho l ether) Bn ( ch loroacetic acid) = 1B113, at 100e , fo r 11 h, to atta in 9514% y ie ld. The surface properties o f different productsw erem easured. The results show thatAEC is as much as AEO7 in the surface tension, more than AEO7 in CMC and less than AEO7 inm icellar agg regation number and that all ofAEC s exhibit good foam ing and detergent and decrease in emulsificat ion and w ettingw ith the increasing number o f EO residue.
