Document Type and Number:
WIPO Patent Application WO/2023/125001
Kind Code:
A1
Abstract:
A cyclic 1,3-diketonediimine compound, and a synthesis method therefor and the use thereof. The cyclic 1,3-diketonediimine compound has a structure as shown in the following general formulas I, II or III, wherein R1-R8 are each independently selected from H, halogen, and a C1-C10 saturated alkyl, where n = 0, 1 or 2. A cyclic β-diimine has a strong binding capacity to an alcohol compound; after same is combined with an alcohol compound by mean of a hydrogen bond, alcohol molecules can only be completely removed under vacuum at 95°C or higher; and the cyclic β-diimine can be used to remove trace alcohol compounds in a compound.
