CAS 100-20-9: Cloruro de tereftaloilo
Descripción:
Cloruro de tereftaloilo, con el número CAS 100-20-9, es un cloruro acilo aromático derivado del ácido tereftálico. Se caracteriza por su forma sólida cristalina blanca y es conocido por su fuerte reactividad debido a la presencia del grupo funcional cloruro acilo. Este compuesto se utiliza principalmente como intermediario en la síntesis de poliésteres y poliamidas, particularmente en la producción de materiales de alto rendimiento como fibras aramidas y elastómeros termoplásticos. Cloruro de tereftaloilo es soluble en disolventes orgánicos como el diclorometano y el cloroformo, pero es insoluble en agua. Es importante manejar esta sustancia con cuidado, ya que puede ser corrosiva y puede causar irritación en la piel, los ojos y el sistema respiratorio. Además, puede reaccionar violentamente con agua, liberando ácido clorhídrico, lo que requiere precauciones de seguridad adecuadas durante su uso y almacenamiento. En general, Cloruro de tereftaloilo desempeña un papel significativo en la industria química, particularmente en el desarrollo de materiales poliméricos avanzados.

CAS:Terephthalaldehyde chloride is a water-insoluble, white solid that is soluble in organic solvents. It forms a protective layer on metal surfaces and plastics, preventing corrosion and microbial growth. Terephthalaldehyde chloride has been shown to be effective against Escherichia coli, Klebsiella pneumoniae, Bacillus subtilis, Pseudomonas aeruginosa, Staphylococcus aureus, and Salmonella enterica. Terephthalaldehyde chloride's antimicrobial activity is attributed to its acid complex with phosphorus pentoxide and electrochemical impedance spectroscopy data indicate that it reacts with the anionic sites of bacterial cell walls. Terephthalaldehyde chloride does not react with human serum proteins or ester linkages; however, it has toxic effects on mice at high doses.Fórmula:C8H4Cl2O2Pureza:Min. 95%Forma y color:PowderPeso molecular:203.02 g/molTerephthaloyl chloride

CAS:Terephthaloyl chloride acts as a monomer with p-phenylenediamine used in the preparation of polymer viz. poly paraphenylene terephthalamide. It is an active component in performance polymers and aramid fibers, which gives flame resistance, chemical resistance, temperature stability, light weight, and very high strength. It is also used as an effective water scavenger, utilized to stabilize isocyanates and urethane prepolymers. Further, it is used in the preparation of liquid crystalline thermosets by thermal cyclotrimerization of dicyanate compounds of ring substituted bis(4-hydroxyphenyl) terepthalates. In addition to this, it is involved in the condensation reaction with difunctional alfa, μ-diaminopolystyrene to get chain-extended polystyrene containing amide bonds along the polymer backbone.
