摘要 technology of preparing industrial sodium formate from aqueous solution of industrial chloral which is chloroform production waste. SUBSTANCE: process is carried out by splitting industrial chloral with sodium hydroxide. Said aqueous solution is evaporated to residual moisture content of 16.8-29.7 wt %, preferably at atmospheric pressure and temperature of 125-132 C.
