Disclosed is a cetane number improver comprising a tetraoxane-based compound having a specific structure. Fuel oil comprising the cetane number improver and a novel tetraoxane-based compound are also provided. The addition of the cetane number improver to fuel oil improves the cetane number of the fuel oil. This cetane number improver has lower toxicity and superior stability, compared to a conventional cetane number improver, and can greatly improve the cetane number of fuel oil such as diesel, thereby increasing combustion efficiency of fuel oil.
Triflic Acid-Functionalized Silica-Coated Magnetic Nanoparticles as a Magnetically Separable Catalyst for Synthesis of gem-Dihydroperoxides
Triflicacid-functionalizedsilica-coatedmagneticnanoparticles [γ-Fe2O3@SiO2-TfOH] were readily prepared and identified as an effictive catalyst for the transformation of aldehydes or ketones into their corresponding gem-dihydroperoxides with 30% aqueous hydrogen peroxide. The catalyst was easily separated by magnetic decantation and the recovered catalyst was reused for seven cycles without significant

An efficient method has been developed for the synthesis of di(tri)peroxysilacycloalkanes by cyclization of geminal bis-hydroperoxides and 1,1′-peroxybis(1-hydroperoxycycloalkanes) with bis(methoxymethyl)diphenylsilane in the presence of lanthanide catalysts. Conditions have been found for the reduction of diphenylhexaoxasiladispirocycloalkanes to diphenyltetraoxasiladispirocycloalkanes.
