The reproducible results obtained by different methods showed that only six cocrystals formed. The crystal structures of the four novel cocrystals, succinic acid?2,2′-bipyridine (1:1, P21/c, I), succinic acid?diphenylcyclopropenone (1:2, P21/c, II), 4-aminobenzoic acid?antipyrine (1:1, P21, III) and 4-aminobenzoic acid?phenazine (1:2, P, IV), are reported. The computed crystal energy landscapes of the cocrystals and their components show why succinic acid(cas:110-15-6) 1,4-dicyanobenzene did not form a cocrystal as well as predicting the observed structure of succinic acid(cas:110-15-6) 2,2′-bipyridine as the most stable. The most stable hypothetical structures of a 1:1 succinic acid(cas:110-15-6) 1,4-dicyanobenzene cocrystal are closely related to those of the components.
Other objects and advantages of the present invention will become apparent as the description thereof proceeds.
In satisfaction of the foregoing objects and advantages, there is provided by the present invention ethoxylated esters of succinic acid(cas:110-15-6) succinic anhydride which are useful as dispersants and more particularly, ester reaction products of long chain hydrocarbyl substituted succinic anhydride with polyethoxylated alcohols and use of these compositions as dispersants or surface active agents.
The present invention also provides an aqueous based hydraulic fluid having characteristics making it particularly suitable for use in water of significant hardness, which composition comprises a dispersant which is an ester reaction product of a hydrocarbyl substituted succinic anhydride with an excess of a polyethoxylated alcohol, a surfactant, corrosion inhibitors and water.
Also provided by the present invention are methods for preparation of the novel dispersant and hydraulic fluid and methods for use of the aqueous based hydraulic fluid of this invention.
