FIRE-EXTINGUISHING FOAM GENERATION COMPOSITION Russian patent published in 2007 - IPC A62D1/04 

FIELD: fire-fighting, particularly fire-extinguishing compositions for class A and B fire extinguishment.

SUBSTANCE: foam generation composition comprises organic synthesis still residue, namely waste obtained during tetramethylene glycol, polyvinylpyrrolidone and gamma-butyrolactone production, during methylpyrrolidone distillation, monoethanolamine regeneration, as well as carbamide, C₁₂-C₁₄ higher fatty alcohols, butanol, cyclohexylamine chromate, glycerin and 35% secondary alkyl sodium sulfate solution. Above components are taken in predetermined ratio.

EFFECT: increased foam stability and expansion rate, improved frost-resistance and fire-extinguishment efficiency, as well as possibility to utilize organic synthesis waste.
