Abstract:

The structure-property relationship of iso-tridecanol polyoxyethylene ether with different number of ethylene oxide (EO) units was studied, as well as their performance after blocking with 3 units of propylene oxide (3PO). The surface tension, critical micelle concentration (cmc), wetting properties, foam properties, emulsifying power and cloud point of iso-tridecanol polyoxyethylene ethers and 3PO-blocked iso-tridecanol polyoxyethylene polyoxypropylene ether were investigated. The results show that the minimum surface tension (γcmc), the cmc, the foam stability and the foaming power, the wetting time and the cloud point of iso-tridecanol polyoxyethylene ether are increased with the increase of the EO number. It is also found that when PO is blocked, its surface tension is increased; the cmc, foam stability, foaming and emulsifying ability and cloud point are decreased; when the EO number is greater than 9, the wetting force is increased. In summary, the structure of polyethers affects their properties.

Key words: iso-tridecanol polyoxyethylene ether, iso-tridecanol polyoxyethylene polyoxypropylene ether, ethylene oxide, propylene oxide, structure-property relationship
