Moreover, the DS tot exceeds the molar ratio of propionic anhydride in some cases when less than three equivalents of propionic anhydride were applied (see samples 4a, 4d, 4e, 4f, and 4m, Table 1). It is assumed that lauric acid and propionic anhydride may form the corresponding mixed anhydride.

It is miscible in any proportion with most organic solvents.
PROPIONIC ANHYDRIDE reacts exothermically with water. The reactions are sometimes slow, but can become violent when local heating accelerates their rate. Acids accelerate the reaction with water. Incompatible with acids, strong oxidizing agents, alcohols, amines, and bases.
