Continuous preparation method of alicyclic epoxy compound
-
Paragraph 0046-0065, (2021/09/29)
The invention provides a continuous preparation method of an alicyclic epoxy compound. The preparation method comprises the following steps: S1, continuously introducing alicyclic olefin and a hydrogen peroxide aqueous solution into a micro-emulsifier for emulsification to form an emulsion, the concentration of the hydrogen peroxide aqueous solution being greater than or equal to 8wt%; s2, continuously introducing the emulsified liquid into a microreactor for oxidation reaction to obtain a crude product mother solution; and S3, purifying the crude product mother liquor to obtain the alicyclic epoxy compound. According to the preparation method, the dynamic micro-channel reactor is adopted, the homogeneity of the reaction system is ensured through the combination of the micro-emulsifier and the micro-reactor, and the problem of poor mixing effect is avoided, so that relatively high reaction conversion rate and yield of alicyclic epoxy compound preparation can be realized by adopting the low-concentration hydrogen peroxide aqueous solution as the oxidizing agent. Besides, a continuous operation process is adopted, so that the process is small in danger, safe and controllable.

Page/Page column 15-16, (2008/06/13)
A high-purity cycloaliphatic diepoxy compound of General Formula (II) is an epoxidized product of a cycloaliphatic diolefinic compound of General Formula (I) having an isomer content as detected in gas chromatography (GC) of 15% or less: wherein X represents a bivalent group selected from the group consisting of, for example, O, S, -SO-, -SO2-, -CH2-, and -C(CH3)2-; and R1 to R18 may be the same as or different from each other and each represent hydrogen atom, a halogen atom, a hydrocarbon group which may contain oxygen atom or a halogen atom, or an alkoxy group which may be substituted. Such a high-purity cycloaliphatic diepoxy compound is prepared by producing the cycloaliphatic diolefinic compound through distillation, epoxidizing the compound with an aliphatic percarboxylic acid containing substantially no water, carrying out desolvation, and further purifying the epoxidized compound through distillation.
