Product Name:2,4,8,10-Tetraoxa-3,9-dithiaspiro[5.5]undecane 3,9-dioxide
English Name:2,4,8,10-Tetraoxa-3,9-dithiaspiro[5.5]undecane 3,9-dioxide
CAS No.:3670-93-7
Aliases:Pentaerythritol disulfite, Pentaerythritol cyclic sulfite, 3,9-Dioxo-2,4,8,10-tetraoxa-3,9-dithiaspiro[5.5]undecane
Molecular Formula:C5H8O6S2
Physical Properties:White crystalline powder, odorless or with a slight pungent smell. Melting point approximately 130 °C (decomposes). Insoluble in water and slowly hydrolyzes in water; soluble in organic solvents such as ethanol, acetone, and chloroform. Relative density approximately 1.5 g/cm³. Heating can cause decomposition with evolution of sulfur dioxide.
Uses:Primarily used as an organic synthesis intermediate for preparing sulfur-containing polymers, flame retardants, and fine chemicals; also applied as an electrolyte additive in lithium-ion batteries to improve film-forming performance. Further used as a monomer for synthesizing pentaerythritol derivatives and functional materials.
Technical Specifications:
Assay (GC) ≥98.0%
Melting point: 128~130 °C
Loss on drying ≤0.5%
Residue on ignition ≤0.1%
Appearance: white to off-white crystalline powder
