Abstract
Inventia se refera la un derivat de benzochinoxalin-5,10-diona si la un procedeu de presare a lui si consta în aceea ca este 2,3-ditio-8-nitrobenzochinoxalin-5,10-diona, substanta cristalina de culoare rosie-purpurie, instabila în prezenta aerului dar care se pastreaza timp nedefinit sub forma de sare de tiouroniu, cu punct de topire la 360 degree C si care este solubila în dimetilfomamida, dimetilsulfoxid si dioxan. Procedeul de obtinere a 2,3-ditio-8-nitro-benzochinoxalin-5,10-dionei, se realizeaza sinteza prin refluxare timp de 2h pe baia de apa a unei solutii etanolice de 2,3-diclor-B-nitrobenzochinoxalin-5,10-diona si tiouree, izolarea produsului în stare pura facîndu-se prin alcalinizarea solutiei cu NaOH si tratarea ei în final cu acid acetic glacial.
