Sulfur vulcanization a reaction with low levels of unsaturated organic linkers (e.g. 1,3‐diisopropenylbenzene). This process is called inverse vulcanisation and produces polymers where sulfur is the main component. It is not currently of commercial importance but had been investigated as a means of producing polymers for lithium–sulfur batterys and for creating water filters with a high affinity for mercury. The curing of rubber has been carried out since prehistoric times. The name of the first major civilization in Guatemala and Mexico, the Olmec, means 'rubber people' in the Aztec language. Ancient Mesoamericans, spanning from ancient Olmecs to Aztecs, extracted latex from "Castilla
Sulfur trioxide in situ from sulfuric acid or is used as a solution in the acid. Along with being a strong oxidizing agent, sulfur trioxide will cause serious burns on both inhalation and ingestion because it is highly corrosive and hygroscopic in nature. SO should be handled with extreme care as it reacts violently with water and produces highly corrosive sulfuric acid. It should also be kept away from organic material due to the strong dehydrating nature of sulfur trioxide and its ability to react violently with such materials. Sulfur trioxide Sulfur trioxide (alternative spelling sulphur trioxide) is the chemical compound with
