Microemulsifying Polar Oils

The phase behavior and microstructure of C12E6/ether oil/water mixtures have been examined systematically as a function of increasing oil polarity.As the ratio of ether linkages to methylene groups of the ether oils is increased, the oils become more water soluble and more polar (less hydrophobic).When ethylene glycol dibutyl ether is replaced with the more polar ethylene glycol diethyl ether in C12E6/ether oil/water mixtures, the three-phase region shrinks and disappears: the system bypasses a tricritical point.Simultaneously, the liquid crystalline region retreats to higher surfactant concentration, and light and X-ray scattering measurements indicate that the microstructure decreases dramatically in size.According to small-angle X-ray scattering results, C12E6/ethylene glycol diethyl ether/water mixtures retain an interface between oillike and waterlike domains.However, since the ether is highly soluble in the water and interface domains, the microstructure is diffuse.

Preparation method for double-terminated glycol ether

The invention relates to a preparation method for double-terminated glycol ether. The preparation method comprises a step of introducing raw materials containing glycol monoether and monohydric ether alcohol into a reactor for contact and reaction with an acidic molecular sieve catalyst so as to produce double-terminated glycol ether, wherein reaction temperature is 50 to 300 DEG C, reaction pressure is 0.1 to 15 MPa, the mass space velocity of the glycol monoether in the raw materials is 0.01 to 15.0/h, and a mol ratio of monohydric ether alcohol to glycol monoether in the raw materials is 1-100: 1. The preparation method has the advantages that the catalyst has long single-pass life and can be repeatedly regenerated; the target product, i.e., double-terminated glycol ether has high yield and selectivity; energy consumption in separation of products is low; by-products have high economic value; production scale can be large or small; and application of the method is flexible.
