Abstract:
A series of branched dodecyl phenol polyoxyethylene ethers (b-DPEO ) were successfully synthesized via alkylation and ethylene oxide addition reactions. The alkylation reaction was conducted by using a branched internal olefin as the raw material. Furthermore, the conversion rate of the branched dodecene was measured to be 98.1% and the selectivity towards branched dodecyl phenol (b-DP) was 95.9%. Moreover, b-DPEO (b-DPEO7, b-DPEO10, b-DPEO12) were obtained via the reaction of ethylene oxide with b-DP. Notably, b-DPEO10 can efficiently reduce the surface tension of water below 31.55 mN m-1 at the critical micelle concentration (cmc) and the cmc value in water was approximately 1.3 × 10-2 g L-1 at 25 °C. The preferable wetting ability of b-DPEO10 was superior to that of commercialized dodecyl phenol polyoxyethylene ether (c-DPEO ), so it will be promoted and used in the textile and pesticide industries.

02:17Physical Properties of Ethers
An ether molecule has a net dipole moment due to the polarity of C–O bonds. Subsequently, boiling points of ethers are lower than those of alcohols of comparable molecular weight and slightly higher than those of hydrocarbons of comparable molecular weight (Table 1).
Ethers can act as hydrogen bond acceptors, making them more water-soluble than hydrocarbons, but since ethers cannot act as hydrogen bond donors, they are much less soluble in water than alcohols. Ethers are considered...
