Several dibasic acid esters containing oxyalkylene units (-OCH
2-, -OC
2H
4-, unit number; 15) were treated with aminimines derived from alkyl (C
8C
12) glycidyl ethers and 1, 1-dimethylhydrazine, giving a new series of bis (aminimides) with the yields of 3040%. The introduction of ether linkage caused a decrease in melting point and Krafft's point of the bis (aminimides). The lower members regarding m (m<3) were more soluble in water and showed high surface activity, but the higher members were less soluble. Cloud point and cmc of these surfactants were found to decrease with increasing m.
They were effective phase-transfer catalysts for aqueous potassium iodide-octyl bromide two phase reaction. Their efficiency increased with increasing m. The efficiency of a higher member (m=5) was much greater than that of dibenzo-18-crown-6 and was close to that of dicyclohexyl-18-crown-6.
