Description
Technical Field

Background
The polyacyl chloride is an important chemical raw material, is mainly used for preparing polyamide, polyester, polyimide and other materials or films, and has wide application in the separation and adsorption fields, such as gas separation membranes, organic solvent nanofiltration membranes, microporous adsorption media and the like.
The method for synthesizing the polybasic acyl chloride monomer comprises the step of reacting polybasic carboxylic acid with an acylating agent to obtain the acyl chloride monomer. The acylating agent is selected from one or more of thionyl chloride, oxalyl chloride, triphosgene and phosphorus pentachloride. In 2005, zhou Yong et al synthesized 5-oxo-isopeptidoyl chloride (CFIC), 5-isocyanatoisopeptidoyl chloride (ICIC) and other acyl chloride monomers using triphosgene (e.g., desalination,2005,180,189-196;Journal of Membrane Science,2006,270,162-168; desalination,2006,192, 182-189). In 2009, li Lei, a plurality of polybasic acyl chlorides containing biphenyl structures were prepared by a method of Suzuki coupling and Ni (0) catalytic coupling and thionyl chloride: 3,4, 5-biphenyltriacyl chloride, 3', 5' -biphenyltetra-acyl chloride, 2', 4' -biphenyltetra-acyl chloride (e.g., document Journal of Membrane Science,2007,289 (1/2): 258-267;Journal of Membrane Science,2008,315 (1-2): 20-27;Journal of Membrane Science,2009,335 (1-2): 133-139). Wang Tun in 2013, 2, 4', 6-biphenyltetra-acyl chloride, 2,3',4,5', 6-biphenylpenta-acyl chloride, and 2,2', 4', 6' -biphenylhexa-acyl chloride were synthesized (e.g., document Journal of Membrane Science,2013,440: 48-57).
However, the polymers generated by the existing polybasic acyl chlorides (such as trimesic chloride and biphenyl tetra-acyl chloride) have no micropore characteristic, and the molecular chains are effectively stacked, and the free volume is smaller, so that the densely stacked structure of the polymer film prevents gas and organic solvent from passing through.
