Kodolov, V. I. published the artcileMechanism of the reaction of diethyl alkylphosphonates with hydroxyl-containing polyethers, Safety of Diethyltrichloromethylphosphonate, the publication is Vysokomolekulyarnye Soedineniya, Seriya A (1968), 10(11), 2541-9, database is CAplus.
Di-Et alkylor arylphosphonates are treated with OH-containing oligoethers to obtain products which are useful as additives possessing fire resistance in foamed plastics, glass reinforced plastics, and other materials. Di-Et phosphonate and methyl-, allyl-, trichloromethyl-, and phenylphosphonates are used, and the oligoethers are HO[CH2CH2O2CRCO]mOCH2CH2OH, where R = -CH2-CH2-, -CH:CH-, or -o-C6H4-, where m is 1-2. The compounds are heated at 160-80° under N. The quantity of condensate increases after 4-6 hrs. with the acid number increasing and the OH-group content decreasing. Chromatograms, kinetic data, and ir spectra are given for the products and discussed, and a mechanism for the reaction, based on the destruction of the oligoether by alcoholysis, followed by a proton-radical exchange between the oligoether and the Et Cellosolve formed is proposed.
Vysokomolekulyarnye Soedineniya, Seriya A published new progress about 866-23-9. 866-23-9 belongs to chlorides-buliding-blocks, auxiliary class Aliphatic Chain, name is Diethyltrichloromethylphosphonate, and the molecular formula is C5H10Cl3O3P, Safety of Diethyltrichloromethylphosphonate.
