Electric Literature of 20358-02-5, Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.20358-02-5, Name is 4-Bromobenzo[d]thiazol-2-amine, molecular formula is C7H5BrN2S. In a patent, introducing its new discovery.
The invention discloses a benzothiazole structure of the triamine monomer and its preparation method and application. The invention from the containing a halogen atom and a amino substituted benzothiazole monomer starting, by the Ullmann coupling reaction, Suzuki reaction, the reduction reaction and a series chemical reaction to prepare benzothiazole structure of the triamine monomer. The invention provides benzothiazole structure of the triamine monomer of high heat resistance and heat stability, preparation method and technique is simple, easy purification, therefore is suitable for industrial production. The invention the benzothiazole heterocyclic introduced into the triamine monomer can remarkably improve the thermal stability of the monomer, can also be improved by the preparation of the polymer thermal stability and mechanical performance, significantly improve its processing performance. The invention of the benzothiazole structure of the triamine monomer can be used for synthesizing hyperbranched and functional polyimide, polyamide, polyamide-imide and polyester imide such as polymer.
