Method for synthesizing tris(dioxa-3,6-heptyl)amine
Abstract
The invention relates to a method for synthesizing tris(dioxa-3,6-heptyl)amine. The conventional method for synthesizing the tris(dioxa-3,6-heptyl)amine has low selectivity, low yield and long production period. The method comprises the following steps of: catalyzing diglycol simple methyl ether serving as a raw material by a framework Cu-Ni bimetallic catalyst in the absence of solvent; and introducing hydrogen and ammonia under normal pressure and at the temperature of between 130 and 150 DEG C with stirring so as to synthesize the tris(dioxa-3,6-heptyl)amine, wherein the feeding volume ratio of the hydrogen to the ammonia is controlled to be 1:(5-10); and when the mass ratio of the diglycol simple methyl ether to 3,6-dioxa amine in reaction solution reaches (1.5-2):1, ammonia introducing is stopped and hydrogen introducing speed is not changed until the mass percentage of the diglycol simple methyl ether is less than or equal to 2 percent. The method has the advantages of high selectivity, high yield, convenient subsequent separation and suitability for industrialized production and the production and preparation of the tris(dioxa-3,6-heptyl)amine.

Disclosed herein are improved methods of enhanced oil recovery and additives therefor. One or more additives, may be added to steam in steam-assisted oil recovery methods resulting in vapor compositions that comprise the additive and steam. The one or more additives may also be added to water, and the resulting water-additive mixture vaporized to provide a vapor composition comprising the additive and steam. Formation of the vapor composition is followed by injection of the vapor composition into a subterranean reservoir including heavy oil and/or bitumen. [0012] The vapor compositions may condense during and/or after injection to form aqueous condensates. Vapor compositions derived from water-additive mixtures comprising, consisting essentially of, or consisting of water and 125 ppm to 250 ppm of one or more additives condense to form aqueous condensates having a lower oil/water dynamic interfacial tension than water alone. For example,
