DBNPA

Content: ≥99% Property: White crystal. Melting point 125 °C, soluble in general organic solvents such as acetone, benzene, DMF, ethanol, polyethylene glycol (peg), etc.), slightly soluble in water at (25 °C, 100 g water dissolved 1.5 g). In its aqueous solution under acid condition is relatively stable, easy to hydrolysis under alkaline conditions. Improve the pH value, heating, using ultraviolet light or fluorescent light, can make its dissolution accelerated dramatically. Easy by reducing agent, such as hydrogen sulfide debromination into non-toxic cyanoacetic acid amine, the sterilization rate is reduced greatly. The pH from 6.7 to 9.7, the half-life is from 37.0 h to 0.11 h. Specification: Items Specification Appearance White or pale yellow crystalline powder Melting Point 122-126°C PH value(1% aqua) 4.0-7.0 Solubility test in 20% EG Colorless or pale yellow clear liquid ≤50 Pt-Co number Solubility test in 20% EG None Loss on drying wt % ≤ 0.5% Purity, WT % ≥99.0% Application: It is a kind of broad-spectrum efficient industrial microbicides to prevent bacteria and algae in paper making, industrial circulating cooling water, metal processing oil, paper pulp, wood, paint and grow in the plywood.
