Abstract
THE position of the second explosion limit of carefully dried mixtures of carbon monoxide and oxygen in quartz vessels has been determined. Both the heating and withdrawal methods were used in a static system. Carbon monoxide was prepared from sodium formate and concentrated sulphuric acid, and oxygen by heating potassium permanganate. After being passed through chemical desiccants and then through cold traps, the gases underwent a final drying operation immediately before use. This final drying consisted in allowing the gases (sometimes premixed) to stand in ‘Pyrex’ drying vessels surrounded by liquid oxygen for at least 12 hr.
