US 2023/0075418 A1 · para-PHENYLENEDIAMINE DERIVATIVE, 1,4-CYCLOHEXYLDIAMINE DERIVATIVE, AND FABRICATING METHOD FOR 1,4-DIAMINE CYCLIC COMPOUND DERIVATIVE

Abstract

A fabricating method for a 1,4-diamine cyclic compound derivative includes: performing a first thermal process to form a first compound, in which the first compound has a structure represented by formula (i): in which R represents a C1 to C12 hydrocarbon group; performing a second thermal process, which includes performing a reduction reaction on the first compound to form a second compound, in which the second compound has a structure represented by formula (ii), and performing a third thermal process, which includes performing a reduction reaction on the second compound to form the 1,4-diamine cyclic compound derivative, in which the 1,4-diamine cyclic compound derivative has a structure represented by formula (I) or formula (II): in which R represents a C1 to C12 hydrocarbon group, in which R represents a C1 to C12 hydrocarbon group.
