process for the preparation of products of hydrogenation of the residue of the terephthalate of dimethyle preparation

摘要

Disclosed is a process which comprises hydrogenating to substantially complete ring saturation material selected from the group consisting of DMT process residue and distilled DMT process residue, and the product of the process. The product obtained from undistilled DMT process residue can be distilled to provide a refined product of improved properties. The reaction product of alcoholic material and the product of the hydrogenation process is useful as a plasticizer and as a fluid polyol which can be reacted with isocyanates to form polyurethane end products such as, for example, foams, coatings, films and the like.
