METHOD FOR OBTAINING CARBON BLACK AND STUDYING ITS ASH CONTENT
Keywords:
acetylene, ash content, X-ray diffraction analysis, surfactants, GOST 55661-2013, GOST 25699.8-90, technical carbon.Abstract
When producing acetylene, the resulting waste contains low molecular weight substances and salt ions. Salt ions are purified by processing in the form of an aqueous solution with a 5% acid solution. Low molecular weight substances are purified with a 1% surfactant solution. After such processing, carbon black is obtained. The purified substance was dried at a temperature of 120 °C and its ash content was examined according to GOST 55661-2013.
