摘要：

Di(2-ethylhexyl) hexahydrophthalate, an environmentally benign plasticizer of polyvinylchloride, could be produced through the hydrogenation of dioctyl phthalate (DOP). The hydrogenation of DOP was compared to that of toluene in this work by using supported nickel catalysts. While the surface acid/base properties significantly affected the activity of toluene hydrogenation, such effect was absent for the hydrogenation of DOP. Such different behavior might be due to the different electron charge distributions among the atoms in the two molecules. Thus, the active nickel surface area and pore size of catalysts might be the two major factors affecting the activity of hydrogenation of DOP. (C) 2011 Elsevier B.V. All rights reserved.
