A plasticizer composition and a resin composition including the same. The plasticizer composition includes a terephthalate-based material including a mixture of dibutyl terephthalate, butyl(2-ethylhexyl) terephthalate and di(2-ethylhexyl) terephthalate; and a glyceride-based material. The plasticizer composition has improved physical properties such as tensile strength, elongation rate and modulus and also has excellent properties attributable to the inclusion of a terephthalate-based material, such as excellent transmittance, transparency and migration loss properties.

The invention relates to a process for preparing carboxylic acids or salts thereof by hydrolysis or saponification of an ester, which is obtained by alkoxycarbonylation of a C2 to C20 hydrocarbon having at least one multiple bond, preferably having at least one olefinic double bond, in which the homogeneous catalyst system used is separated from the product mixture by means of membrane separation. In a development of the present invention, the ester thus formed is converted into another ester by transesterification and then hydrolyzed or saponified.
