    Abstract: The present disclosure relates to an apparatus for generating glycol and a method thereof. More particularly, the present disclosure relates to an apparatus for generating glycol including (a) an aldol reactor; (b) an extractor for extracting an aldol product, unsaturated aldehyde, using an organic solvent that is not mixed with water; (c) a distillation column for removing a raw material from a solution extract that is discharged from the extractor; (d) a hydrogenation reactor for hydrogenating a solution extract that is discharged from the distillation column; and (e) a divided-wall distillation column for isolating glycol from a hydrogenated solution product that is discharged from the hydrogenation reactor, wherein the hydrogenation reactor is a fixed-bed catalytic reactor that is filled with a copper-based catalyst, and a method of preparing the same.In accordance with the present disclosure, an economical apparatus for preparing glycol which reduces loss of a raw material and provides a high glycol yield while inhibiting generation of by-products, and a method of preparing the same are provided.

    Abstract: An ester composition including terephthalate compounds substituted with a non-hybrid and non-branch type alkyl group, a hybrid and branch type alkyl group, and a non-hybrid and branch type alkyl group, respectively by 0.5 wt % to 9.5 wt %, by 14.5 wt % to 43.8 wt %, and 46.7 wt % to 85 wt % based on the total weight of the ester composition, a method of preparing the same, and a resin composition including the same are provided. The ester composition has a short absorption time with respect to the resin and short fusion time and improves the processability of the resin composition. In addition, good physical properties may be provided when manufacturing a sheet and a compound such as a cable, an interior of a car, a film, a sheet, a tube, a wallpaper, a toy, a flooring material, and the like.
