gas of a calcium carbide furnace is removed by a drying method and a wetting method; the tail gas is washed with alkali; coal tar is removed; and after CO purification treatment is finished, the tail gas is transmitted into an oxalic acidcompounding device and reacts with sodium hydroxide....
Oxalic acid is catalytically reduced by hydrogen in the presence of ruthenium catalyst to ethylene glycol, and electronically reduced to glyoxylic acid. Oxalic acid reacts with various metals to form metal salts, which are quite important as the derivatives of oxalic acid. It also reacts easily ...
This compound may react violently with furfuryl alcohol, silver, sodium, perchlorate, sodium hypochlorite, strong oxidizers, sodium chlorite, acid chlorides, metals and alkali metals. . The heating of mixtures of Oxalic acid and urea has lead to explosions. This is due to the rapid generation of...

Sodium hydroxide (NaOH) and oxalic acid (OA) were selected as the alkaline and acid additives, respectively, to investigate whether acid and alkaline additives could promote oxidative desulfurization in the UVH 2 O 2 system. The coal samples were investigated via scanning electron microscopy (SEM)...
Oxalic acid reacts with various metals to form metal salts, which are quite important as the derivatives of oxalic acid. It also reacts easily with alcohols to give esters. General DescriptionOdorless white solid. Sinks and mixes with water. ...
