4,4’-Dibenzoic acid is one of the important monomers for the synthesis of general-purpose high-performance polymers and liquid crystal materials. However, this monomer has shortcomings such as long industrial synthesis route, heavy pollution, low selectivity, and poor biodegradability of the synthesized polymer. Under increasingly severe environmental control and carbon neutrality restrictions, its industrial production and polymer application have become increasingly difficult. Subject to many restrictions. Therefore, it is of great significance to develop alternatives to 4,4’-bibenzoic acid.
J&K Scientific exclusively sells 2,2’-difuran-5,5’-dicarboxylic acid, the scientific research result of Professor Yin Guochuan of Huazhong University of Science and Technology.
Product advantages:
It has a similar structure to 4,4’-biphenyldicarboxylic acid, but the polymer product is biodegradable, which solves the problems of carbon neutrality restrictions and serious environmental pollution faced by the production of 4,4’-biphenyldicarboxylic acid.
