Additional information

HATCOL 1765

The dissociation constant of the substance pentaerythritol tetraesters of n-decanoic, n-heptanoic, n-octanoic and n-valeric acids (CAS 68424 -31 -7) was determined by QSAR calculations with SPARC (v4.5) for the two exemplary components covering both ends of the substance specification. No dissociation could be determined within the range pH = -0.2 -14.
