Abstract: Polyoxyethylene isotridecanol ether  is one of the  novel nonionic surfactants which was developed on the purpose of partially replacing a potentially carcinogenic  and reproductive toxicity surfactant, polyoxyethylene nonyl phenyl ether in some application areas. While the properties and the performance were well heavily relied on the distribution of the ethoxylates. Conventional homogeneous alkaline catalyst other than heterogeneous alkaline earth metal oxides were examined in order to obtain the narrow distributed ethoxylates by a loop reaction process. Catalyst, feed ratio and other reaction conditions were well investigated in this paper. The optimized reaction conditions were as following: isotridecanol and ethylene oxide of  1 to 3 mole ratio were reacted at 120oC , 0.2 MPa partial  pressure of ethylene oxide which was catalized by 0.3 % (wt) potassium hydride. The properties and the performance were also measured and compared with the commercial products.

Key words: Polyoxylene isotridecanol, Ethoxylation, Catalyst, Narrow distribute ethoxylates,
