OBTENTION DE SOLUTIONS D'OTA EN MILIEU ACIDE SULFURIQUE CONCENTRE; LESDITES SOLUTIONS; PREPARATION D'ONTA.
摘要:
The present invention relates to a method for obtaining solutions that contain 1,2,4-triazole-5-one (3) (OTA) in concentrated sulphuric acid, said method using 3-amino-1,2,4-triazole (1) (ATA) as a precursor of OTA (3); to said solutions and to a method for preparing 3-nitro-1,2,4-triazole-5-one (4) (ONTA) from said solutions.
