Provided is an alicyclic epoxy compound product used in applications for forming a cured product excellent in transparency and heat resistance. An alicyclic epoxy compound product of the present disclosure has a purity of a compound represented by Formula (1) of 85 wt. % or greater; and a total content of a compound represented by Formula (a) and a compound represented by Formula (b) of 0.5 wt. % or less, where X represents a single bond or a linking group. The alicyclic epoxy compound product of the present disclosure can be produced through subjecting a compound represented by Formula (1″) to a dehydration reaction to obtain a compound represented by Formula (1′), and reacting the resulting compound represented by Formula (1′) with an organic peracid.

Alicyclic epoxy compound product

Provided is an epoxy-amine adduct. The epoxy-amine adduct is a compound that may be a compound I containing two or more amino groups per molecule, a compound corresponding to the compound I, except being modified with a compound II-1 containing two or more (meth)acryloyl groups per molecule, a compound corresponding to the compound I, except being modified with a lactone II-2, or a salt of the compound I. The compound I is an adduct between an epoxide (A) containing two or more cycloaliphatic epoxy groups per molecule and an amine (B) containing two or more amino groups per molecule. The compound I includes a constitutional unit represented by Formula (I) and a constitutional unit represented by Formula (II) and contains amino groups at both ends. Formulae (I) and (II) are expressed as follows: 

Epoxy-amine adduct, thermoplastic resin composition, sizing agent, sizing agent coated carbon fiber, and fiber-reinforced composite material
