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
