《Devulcanization of natural rubber industry waste in supercritical carbon dioxide combined with diphenyl disulfide》 was written by Asaro, Lucia; Gratton, Michel; Poirot, Nathalie; Seghar, Said; Ait Hocine, Nourredine. COA of Formula: C12H10S2 And the article was included in Waste Management (Oxford, United Kingdom) in 2020. The article conveys some information:
The elimination of rubber wastes without affecting the environment is one of the most important challenges of the 21st century waste management. Accordingly, the present work is focused on the recycling of natural rubber (NR) industry waste by means of devulcanization in supercritical carbon dioxide (scCO2) atm. With that aim, a novel device allowing to perform rubber devulcanization was developed. It consists of a triaxial compression reactor integrated into a dynamic hydraulic universal testing machine with a heating chamber. NR industry waste was devulcanized in the mentioned device at different temperatures, in scCO2 by using di-Ph disulfide (DD) as devulcanizing reagent. The devulcanization degree and quality of the treated materials were evaluated by the swelling test combined with the Horikx theory. It was appeared that a successful devulcanization, with almost no degradation, was obtained, and the devulcanization degree reached maximum value of ∼90%. Thermogravimetric tests and SEM (SEM) images strengthened these results. Finally, it was concluded that the developed device is appropriate to perform rubber recycling, which contributes to the progress in the environmental protection. In the experimental materials used by the author, we found 1,2-Diphenyldisulfane(cas: 882-33-7COA of Formula: C12H10S2)
1,2-Diphenyldisulfane(cas: 882-33-7) belongs to ethers.Ethers do have nonbonding electron pairs on their oxygen atoms, and they can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. COA of Formula: C12H10S2 The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.
