Beschreibung
Zusammenfassung:	The invention relates to a method of assessing o-chlorobenzylidene malononitrile by measuring the light intensity after a preliminary solubilization thereof in a solvent selected from ethyl alcohol, benzene or chloroform. The hydrolysis of o-chlorobenzylidene malononitrile takes place in a basic medium, directly in the measuring tank of the apparatus by tangential pneumatical stirring or by barbotage with fresh air. Invenţia se referă la o metodă de determinare a o-clorbenzilidenmalononitrilului prin măsurarea intensităţii luminoase, după o prealabilă solubilizare a acestuia într-unul din solvenţii aleşi dintre: alcool etilic, benzen sau cloroform. Hidroliza o-clorbenzilidenmalononitrilului se efectuează în mediu bazic, direct în cuva de măsurare a aparatului, sub agitare pneumatică tangenţială sau prin barbotare cu aer curat.
