| titleOfInvention | 1,3,5-tris(phenylglyoxalyl)benzene as monomer or as comonomer for thermoreactive polyphenylquinoxalins synthesis |
| abstract | The invention relates to trifunctional og- (diketones), in particular 1,3,5-tris (phenylglyoxalyl) benzene of the formula 1,3,5- (СБН5СОС) sСбНз as a monomer or comonomer for the synthesis of thermosetting polyphenylquinoxalines, cured at 230- 290 ° C. The goal is to create a new compound, the use of which allows to obtain thermosetting polyphenylquinoxalines, which harden at 230-290 ° C. Synthesis is carried out by condensation of trimethyl ester of trimezine acid with phenylacetonitrile in the presence of sodium hydride to obtain tris (/ -ketonitrile) trimesic acid and its subsequent hydrolysis and decarboxylating by boiling with sulfuric acid, followed by oxidation of the selenium oxide by boiling in a hydrogen oxide with boiling with sulfuric acid, followed by oxidation of the selenium with boiling silica, by using a w / w material, using the acetic acid, by using a w / w material, to change the pressure, using the w / w material, to change the pressure, using the w / w, to change the pressure, using the w / e, using the w / s, to change the pressure, using the w / s, using the w / s, using the w / s, using the w / s, using the w / s, using the w / s, using the w / s, using the w / s, using the w / s, using the w / s, using the w / s, to transfer the pressure in the w, using the w / s, using the w / e material, by using the w / e material, this will oxidize the oxygen in the form of a mixture of hydrogen, sulfur dioxide and boil; product. Yield 75%, tons, mp 197-198 ° C. 2 tab. sl C |
