Interm e diate product, dodecy l g lycerol ether w as first synthesized and then reacted w ith sod ium ch lo roacetate to obta in the product. T he inf luenc ing factors, such as react ion tem perature, tmi e, m o lar ratio, the am oun t of sodium hydrox ide and react ion m ethod w ere studied. T he appropriate reaction conditionsw ere obta ined as fo llow s: w ith 50% of sodium hydrox ide, n dodecy l glycero l ether) n ch loroace tic ac id sod ium ) = 11. 2, using cyc lohexane as aqua, reacting for 6 h at 150 , the am ount of active m atter reached 87. 6% . Surfactant propert ies w ere m easured, the resu lts show ed that it has good surface tension reduc tion, capac ity increase perfo rm ance and foam stab ility.
