Description

technical field

[0001] The present invention relates to a preparation method of diphenol-based propane diglycidyl ether, more specifically, the present invention is a method for preparing diphenol-based propane diglycidyl ether by utilizing by-products produced during the production of diphenol-based propane. Background technique

[0002] The by-products of diphenol-based propane refer to the by-products of the production of diphenol-based propane, which are composed of diphenol-based propane isomers, aromatic unit phenols, aromatic dihydric phenols, and aromatic polyphenols. Usually, diphenol-based propane residues are collected and sold externally for the production of phenolic resins, which fails to fully reflect the economic and social benefits of diphenol-based propane residues.

[0003] The production method of diphenol-based propane diglycidyl ether is generally: the ring-opening reaction of diphenol-based propane with an equivalent or slightly excess epichlorohydrin ...
