An embodiment of the present invention provides a method for preparing hydrogenated bisphenol A, comprising: (a) heating a reactor in which bisphenol A, a solvent, and a ruthenium supported catalyst are added; (b) supplying hydrogen into the reactor to react; and (c) blocking the supply of hydrogen to react.

Method for preparing hydrogenated bisphenol A

A styrenated phenol compound in which a hydrazine or a diaminoalkane compound binds to a styrenated phenol, and a method of preparing the same are provided. The styrenated phenol compound may have improved exterior quality and storage stability of a product by maintaining a hardening stimulation property and plasticity and preventing discoloration when mixed with a hardener for an epoxy paint.

Styrenated phenol compound and a method of preparing the same

Provided is a styrenated phenol compound represented by Formula 1 in which styrenated phenol and hydroxylamine bind to each other: In Formula 1, n is one of integers of 1 to 3, and Rand Rare each hydrogen or one of C1 to C4 alkyl groups. The styrenated phenol compound may maintain curing stimulation property and plasticity, and prevent discoloration when being mixed with a curing agent for an epoxy paint, thereby enhancing exterior quality and storage stability of a product.
