Sulfur vulcanization in the processing and compounding of rubber by Hancock and his colleagues led to a more reliable process. Around 1900, disulfiram was introduced as a vulcanizing agent, and became widely used. In 1905 George Oenslager discovered that a derivative of aniline called thiocarbanilide accelerated the reaction of sulfur with rubber, leading to shorter cure times and reducing energy consumption. This breakthrough was almost as fundamental to the rubber industry as Goodyear's sulfur cure. Accelerators made the cure process faster, improved the reliability of the process and enabled vulcanization to be applied to synthetic polymers. One year after his discovery, Oenslager
The Sulphur Institute Symposium. The symposia are attended by producers, consumers, and traders in sulfur, as well as industry service providers, and feature speakers discussing a range of topics relating to sulfur. The 2010 Sulphur World Symposium was held in Doha, Qatar, from April 12 through April 15, 2010. The 2010 symposium featured a tour of the Ras Laffan Industrial City, which is not normally available to the public. Publications by The Sulphur Institute include market studies, industrial publications, general brochures about sulfur, and brochures on the agricultural uses of sulfur. Symposium proceedings are also available. Most publications are available in English, with
