Abstract: Due to the unique emulsification and wettability of polyoxyethylene 2-ethylhexanol ether, the nonionic surfactants have been widely applied in many areas, especially been utilized for replacing a potentially carcinogenic and reproductive toxicity surfactant, polyoxyethylene nonyl phenyl ether. While the reaction of commercial primary alcohol with branched alkyl has not well been known. The kinetic parameters, reaction rate constants, of the chain reaction were investigated by the intrinsic kinetics. The kinetic parameters were further compared with those of 1-octanol or 2-octanol. The results suggested that the ethoxylation rates of 2-ethylhexanol is more than that of 2-octanol, and less than that of 1-octanol; and the product distribution is related to the step kinetic parameters of the chain reaction which was catalized by different alkaline.

Key words: polyoxyethylene 2-ethylhexanol ether, Ethoxylation, Catalyst, Kinetic parameters ,
