Ethylhexyl Phthalate

Some theories of homogeneous nucleation based on liquid droplet model were tested by comparing with experimental supersaturations of naphthalene, phthalic anhydride, stearic acid, bis(2-ethylhexyl) phthalate, and bis(2-ethylhexyl) sebacate required to bring about the rate of homogeneous nucleation of about 5 drops/cm3 s-1. It was found that except for highly polar substance phthalic anhydride, the classical (Becker-Doring) theory of homogeneous nucleation, if suitably scaled, yielded fairly good predictions of the nucleation behaviour.

Hydrated Titanium

Using synthetic, chromatographic and spectral methods, we studied the side reactions accompanying the preparation of di-2-ethylhexyl phthalate from phthalic anhydride and 2-ethyl-hexane-1-ol in the presence of catalytic amounts of tetra-n-butyl titanate.The catalyst proper was titanium(IV) mono-2-ethylhexyl phthalate. The possibility of a simultaneous gas-chromatographic quantitative determination of mono-2-ethylhexyl phthalate, di-2-ethylhexyl phthalate, 2-ethylhexane-1-ol and tetra-n-butyl titanate, reported in the literature, has been refuted. In the esterification catalysed by hydrated titanium dioxide homogeneous catalysis by the formed organotitanate was dominating. The dissolving of hydrated titanium dioxide in the esterification of phthalic anhydride with 2-ethylhexane-1-ol was studied polarographically.
