A crystalline dialdehyde, believedto be fumaric dialdehyde, has been isolated from the acid hydrolysis of dimethoxydi- hydrofuran, and its infrared and ultraviolet ...
1) is comparable to analogous com- pounds in showing two absorption peaks,14 225. m p (E 17,000) and 354 mp (E 70). The infrared curve of fumaric.

current for both waves is essentially equal to that for the single wave in the low pH region. Above pH 8, the second maleic acid wave begins to disappear and is.

From these values it can be seen that maleic is the stranger of the two acids and in solution in moderate concentration will have a p H belowpK,, thus causing the ...
