Chlorine Containers

Sulfuryl chloride is produced in a closed loop by reaction of sulfur dioxide and chlorine in the presence of activated carbon. The crude product that contains about 0.5% of sulphur dioxide and 0.1% of chlorine is freed from excess SO2 or Cl2 by distillation. Sulphuryl Chloride is a colorless to light yellow heavy liquid with obnoxious smell. The container of sulphuryl chloride fumes on opening. On prolonged storage, sulphuryl chloride decomposes partly into the starting substances namely sulphur dioxide and chlorine. The container of sulphuryl chloride bloats on long storage and bumps appear on the outer side of HDPE plastic containers. In air, sulphryl chloride is affected by air humidity leading to hydrolysis products viz. hydrochloric acid and sulphuric acid.
