No. 4,522,630 has disclosed the use of tetrahydro-2,5-furandimethanoldinitrate as a cetane improver for diesel fuels. Although many of these polynitrate esters will function well as cetane improvers, their use is hazardous in that they are explosives and are difficult to handle safely. Polyvinyl nitrate (abbreviated: PVN) is a high-energy polymer with the idealized formula of [CH2CH(ONO2)]. Polyvinyl nitrate is a long carbon chain (polymer) with nitrate groups bonded randomly along the chain. PVN is a white, fibrous solid, and is soluble in polar organic solvents such as acetone. PVN can be … See more Polyvinyl nitrate was first synthesized by submersing polyvinyl alcohol (PVA) in a solution of concentrated sulfuric and nitric acids. This causes the PVA to lose a hydrogen atom from its hydroxy group (deprotonation), … See more Combustion Polyvinyl nitrate is a high-energy polymer due to the significant presence of groups, similar to See more • Nitrate ester • Polyvinyl ester • Vinyl polymer See more PVN is a white thermoplastic with a softening point of 40-50°C. The theoretical maximum nitrogen content of PVN is 15.73%. PVN is a polymer that has an atactic configuration, meaning the nitrate groups are randomly distributed along the main chain. Fibrous … See more Because of the nitrate groups of PVN, polyvinyl nitrate is mainly used for its explosive and energetic capabilities. Structurally, PVN is … See more suzana kledingreparatie
