Zusammenfassung: | 1,177,718. Oil emulsion. CHEVRON RESEARCH CO. 29 Nov., 1967 [5 Dec., 1966], No. 54425/67. Heading B1V. [Also in Division C5] An easily-broken oil-in-water emulsion which may be made with sea-water contains from 0.04% to 10% based on the water of a non- ionic surfactant, and from 5 to 75% based on the oil-water mixture of water. Many suitable surfactants are listed of the ether, ester, amide, and multiple linkage types; the most preferred are the nonylphenoxypoly(ethyleneoxy)ethanols. The emulsion may be broken by heating to a temperature of from 200F. to 250F. |
