STUDY OF HYDRATION OF OXYETHYLATED DODECANOL BY THE NMR METHOD.

Abstract

Aqueous solutions of oxyethylated dodecanols C//1//2H//2//5(-CH//2-CH//2-O)//5//6OH (OEPEG-56) were investigated by the NMR'H method as a function of the component ratio in the SAM-water mixture at 20, 40, and 60 degree . It was established that the effect of OEPEG-56 on the mobility of the bonded water molecules, the number of which decreases from n equals 5. 5 to n equals 3. 5 H//2O/OE, decreases with an increase in temperature. The effect of OEPEG-56 virtually does not show up on the electronic environment of the water molecule at these moisture contents. The activation energy of molecular mobility was calculated.
