Abstract

Inventia se refera la un procedeu de obtinere a diacetilmonoximei, caracterizat prin aceea ca, se trateaza n- butanol cu solutie apoasa de nitrat de sodiu. reactantii fiind luati în raport de greutate de circa 1 : 1, la temperatura de 0 degree C, apoi în amestecul rezultat este adaugat acid clorhidric mentinînd temperatura la cel mult +5 degree C, iar amestecul de reactie este preclucrat în vederea separarii nitrilului de butil obisnuit cu care în continuare se trateaza un maestec format din metiletilcetona si acid clorhidric la temepratura de 30...55 degree C, amestecul fiind prelucrat în vederea separarii diacetilmonoximei.The invention relates to a process for obtaining diacetyl monoxime, characterized in that n-butanol is treated with aqueous sodium nitrate solution. the reactants being weighed at about 1: 1 at 0 ° C, then hydrochloric acid is added to the resulting mixture maintaining the temperature at no more than +5 ° C, and the reaction mixture is pre-worked up to separate the butyl nitrile which is usually treated with a methyl esters of methyl ethyl ketone and hydrochloric acid at a temperature of 30 ... 55 ° C, the mixture being worked up to separate the diacetyl monoxime.
