Chemiluminescent oxidation of phosphonates : Phospha-1,2-dioxetanes as possible intermediates
摘要:
Chemiluminescence was observed in autooxidation of the phosphonate carbanions and the related reaction, which gave a strong proof of phospha-1,2-dioxetanes as the intermediates in these reactions.

There is provided a crosslinkable fluorine-containing rubber composition being capable of giving a fluorine-containing rubber crosslinked and molded article having a low friction coefficient and assuring an increased proportion of a fluorine-containing resin around the surface of a fluorine-containing rubber, a molded article obtained by crosslinking the composition, and a method for producing the molded article. The crosslinkable fluorine-containing rubber composition comprises a fluorine-containing rubber (A) comprising vinylidene fluoride unit, a fluorine-containing resin (B) and a polyol crosslinking agent (C),
wherein the fluorine-containing rubber (A) and the fluorine-containing resin (B) are kneaded at a temperature of not less than a temperature being lower by 5°C than the melting point of the fluorine-containing resin (B).

Enthalpies of formation enthalpies of a series of phosphorous acid derivatives were estimated from the heat effects of their reactions. The collected thermochemical data was used to analyze, on the basis of the additive scheme, the experimental enthalpies of formation and vaporization of four-coordinate phosphorus derivatives.
