Additional information

The vapour pressure of the substance 2 -butenedioic acid (E)-, di-C12 -18 -alkyl esters (CAS 68921 -51 -7) was estimated using calculated data (SPARC v4.6) in a weight of evidence approach. The values for single boundary components C12 and C18 were calculated and the results were 2.71E-11 Pa and 3.95E-15 Pa, respectively. Thus, the substance is non-volatile.
