- CEL-3000 since the carbon constituting the epoxy group has a methyl group, the reactivity of the epoxy group is lower than that without the methyl group.
- CEL-2021P and CEL-2081 are hydrolyzable because they have an ester bond in the molecule. Therefore, when used under high temperature and high humidity, or when conditions such as strong acid are generated, the physical properties of the cured product may deteriorate. For this reason, An epoxy compound having an alicyclic skeleton having no steal bond is desired.
- JP-A-48-29899 discloses the following compound (II)
- this percarboxylic acid is a trace amount, it contains hydrogen peroxide and acid catalyst that can be obtained only by moisture, so that the percarboxylic acid becomes unstable in the reaction process and extraction process for producing the percarboxylic acid.
- the concentration may decrease in a short time. Concentration reduction also generates oxygen at the same time, putting the reactor in an extremely dangerous state, and side reactions of the epoxide occur in the epoxy reaction process and the purification process of the generated epoxy compound. This is an industrially disadvantageous method because the production equipment is contaminated with the products of side reactions that become easier and the amount of product recovered is less.
