1.What is the Isophthaloyl dichloride ?

Isophthaloyl dichloride (IPC) is an organic compound used as an important intermediate. Isophthaloyl dichloride is used in a variety of performance polymers and fibers, where it impacts flame resistance, temperature stability, chemical resistance, and flexibility. In addition, it is an effective stabilizer for urethane prepolymers due to its ability to scavenge water. Also used in aromatic fiber raw materials.

5.What is 1,3-Benzenedicarbonyl chloride (99-63-8) used for?

Isophthaloyl dichloride is commonly used in the production of high-performance polymers such as aramids and liquid crystal polymers. It is a key intermediate in the synthesis of polyaramid fibers, which have high tensile strength, thermal stability, and chemical resistance, making them useful in applications such as protective clothing, aerospace materials, and bulletproof vests. NBD-hydrazine was reacted with isophthaloyl dichloride in THF to synthesize isophthalo-NBD.  Isophthaloyl dichloride is also used in the production of liquid crystal polymers, which have unique properties such as high strength, low dielectric constant, and low coefficient of thermal expansion, making them useful in electronic and automotive applications. Additionally, Isophthaloyl dichloride is used as a cross-linking agent in the synthesis of epoxy resins, which are widely used in adhesives, coatings, and composites.

Abstract

Enhanced both water flux and salt rejection of reverse osmosis membrane through combining isophthaloyl dichloride with biphenyl tetraacyl chloride as organic phase monomer for seawater desalination

, Journal of Membrane Science Volume 522, 15 January 2017, Pages 175-182

In this work, we prepared a novel class of polyamide thin composite film membranes for sea water desalination using isophthaloyl dichloride (IPC) and 3,3′,5,5′-biphenyl tetraacyl chloride (BTEC) as mixed organic monomer.

Entry point into new trimeric and tetrameric imide-based macrocyclic esters derived from isophthaloyl dichloride and methyl 6-aminonicotinate

, Acta Cryst. (2013). B69, 62-69

The one-step reaction of isophthaloyl dichloride with the 2-aminopyridine derivative (methyl 6-aminonicotinate) yields (i) a trimer-based macrocycle (EsIO)3 and (ii) a tetramer-based macrocycle (EsIO)4 in modest isolated synthetic yields (total of 25%), together with (iii) longer open-chain oligomers. The macrocyclization relies on the semi-flexible imide hinge formed by reaction of the 2-amino(pyridine) functional group with two acyl chloride functional groups.
