Abstract
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.
Claims16
An alicyclic epoxy compound product, wherein a purity of a compound represented by Formula (1) which is present in the product in an amount of 85 wt. % or greater based on a total weight of alicyclic epoxy compound;
- and a total content of a compound represented by Formula (a) and a compound represented by Formula (b) based on the total weight of alicyclic epoxy compound is from 0.5 wt % or less:
- wherein X of formula (1), (a) or (b) represents a single bond,
- wherein the alicyclic epoxy compound product is made by:
- (1) subjecting a compound represented by Formula (1″) to a dehydration reaction to obtain a compound represented by Formula (1′):
- wherein X of formula (1″) or (1′) represents a single bond;
- (2) reacting the compound represented by Formula (1′) with an organic peracid to obtain a reaction product containing the compound represented by Formula (1);
- and
- (3) fractionally distilling the reaction product using a rectification column with a number of actual plates from 1 to 20 under the conditions below:
- a column bottom temperature of 100 to 250° C.,
- a column top temperature of 80 to 200° C.,
- a column top pressure from 0.1 to 50 mmHg, and
- a column bottom pressure from 1 to 200 mmHg.

- wherein said method comprises:
- (1) subjecting a compound represented by Formula (1″) to a dehydration reaction to obtain a compound represented by Formula (1′):
- wherein X of formula (1″) or (1′) represents a single bond or a linking group;
- (2) reacting the compound represented by Formula (1′) with an organic peracid to obtain a reaction product containing the compound represented by Formula (1);
- and
- (3) fractionally distilling the reaction product using a rectification column with a number of actual plates from 1 to 20 under the conditions below:
- a column bottom temperature of 100 to 250° C.,
- a column top temperature of 80 to 200° C.,
- a column top pressure from 0.1 to 50 mmHg, and
- a column bottom pressure from 1 to 200 mmHg.
