| titleOfInvention | Process for the purification of 1,4-benzoquinone guanylhydrazone thiosemicarbazone (ambazone) |
| abstract | The invention is relates to a process for the purification of 1,4-benzoquinone guanylhydrazone thiosemicarbazone (ambazone) in two steps. At the first step, it takes place the removal of sulfur from ambazone by maceration of ambazone in a non-polar solvent (benzene, n-hexane, toluene or xylene). At the second step, it takes place the recrystallization of ambazone from a mixture N,N-dimethylformamide and lower aliphatic alcohols (C1-C4) at temperatures between 50-80 DEGREE C. |
