WebWhen using continuous scrubbers for phosgene removal, the pH control setpoint is usually pH 10. Maintaining this value is important as too high a pH will reduce the solubility of sodium carbonate and sodium chloride, which may cause scaling and clogging of downstream units. Too low a pH reduces phosgene absorption, which is dangerous due … WebPhosgene is used as an intermediate in the manufacture of many organic chemicals. The largest amount (approximately 80% of world production) is used to produce toluene diisocyanate and other isocyanates used in polyurethane foam production, preparation of plastics, and pesticides.
