Influence of various indexes of calcium hydroxide desulfurizer on the effect
The alkalinity mainly affects the dissolution rate of H2S in the alkaline liquid film and the degree of further dissociation of dissolved H2S. According to the material introduction, the dissociation degree of H2S increases with the increase of pH, but it is not proportional to pH. When pH is 7-9, the desulfurization ability is higher.

Common compounds of oxygen family elements-sulfuryl chloride
Sulfuryl chloride (also known as sulfonyl chloride) is a compound formed after the two-OH groups of sulfuric acid are replaced by chlorine. The molecular formula is SO2Cl2. It is a colorless liquid with a strong pungent smell. It emits smoke in humid air and has a boiling point of 69.1 ℃. It is used as a chlorination reagent in organic chemistry, which can convert the C- H bonds of alkanes, alkenes, alkynes and aromatic compounds into C- Cl bonds, and convert alcohols into chlorinated hydrocarbons
