The decompositionof 3-sulfolene to form 1,3-butadiene generates 1 moleof sulfur dioxide gasper mole of 1,3-butadiene. Substantial quantities of SO2 would be generated if this decomposition were carried out on a large scale. Suggest a method for trapping the gas to prevent its escape into the environment.
This question is a major industrial problem because SO2 is easily dissolved in water, yielding sulfurous acid:
SO2(g) + H20(l) —-> H2SO3(aq)
The acid will of course lower the pH of the water (with substantial biological impact) and also attack all substances vulnerable to acids in standard acid base reactions …
This solution is provided in 223 words. It discusses the issue of SO2 dissolved in water, and discusses wet scrubbers as a method of trapping the gas.
