Singh, Ajit Shankar;Shukla, S. K.;Mishra, Preeti;Pandey, A. K. research published 《 Synthesis and thermal evaluation of novel mono- and bis-adamantylated resorcinol-based phthalonitrile resins with enhanced solubility》, the research content is summarized as follows. Phthalonitrile (PN) resins are high-temperature-resistant thermosetting polymers which find applications in military as well as aerospace owing to their outstanding performance. At present, most of the PN resins are melt-processed and cured at high temperature via resin transfer molding owing to their poor solubility in common organic solvents. In the present, embodiment efforts have been made to change the PN resin backbone with adamantane as potential functionality. Mono- and novel bis-adamantylated resorcinols 1a and 1b have been synthesized via Amberlyst-15 solid acid resin-catalyzed Friedel-Crafts alkylation reaction, as precursor material for the synthesis of novel phthalonitrile (PN) resin monomers 2a and 2b, resp. The study includes structural and thermal characterization of resin monomers 2a and 2b along with their solubility in common organic solvents. These resins when cured to their thermosets have demonstrated thermal stability ~723 K (5% mass loss) with no glass transition temperature (Tg) up to 673 K. The resin monomers show very good solubility in industry-friendly organic solvents like acetone, Et acetate, Me Et ketone and Me iso-Bu ketone.
Application In Synthesis of 31643-49-9, 4-Nitrophthalonitrile, also known as 4-Nitrophthalonitrile, is a useful research compound. Its molecular formula is C8H3N3O2 and its molecular weight is 173.13 g/mol. The purity is usually > 95%.
4-Nitrophthalonitrile is a chemical substance that can be synthesized by the reaction of sodium carbonate with 3,4,5-trimethoxybenzyl alcohol. It can also be prepared using nitro phenol and sodium hydroxide. 4-Nitrophthalonitrile has been shown to have high photochemical activity in the presence of light. The frequency shift of its infrared spectrum is indicative of a nucleophilic addition reaction mechanism. 4-Nitrophthalonitrile has been used as an intermediate for producing other chemicals, such as herbicides and pharmaceuticals., 31643-49-9.
