Crook, James W. published the artcileBehavior of halogen-containing phosphates and phosphonates in urethane foam, COA of Formula: C5H10Cl3O3P, the publication is Journal of Cellular Plastics (1969), 5(2), 119-22, database is CAplus.
(ClCH2CH2CH2O)3P:O (I) was as effective as (ClCH2CH2O)3P:O (II) as a flame-retardant in urethane foam, but had a lower chem. reactivity than II and thus caused less scorch. Foam was prepared from oxypropylated glycerol 100, II 10, (C7H15CO2)2Sn 0.5, triethylenediamine 0.1, H2O 3.5, siloxane-oxyalkylene copolymer 1.0, and tolylene diisocyanate 45.4 parts. Prior to aging, 90% phosphate could be removed by extraction with boiling C6H6. After aging 48 hrs. at 140°, only 1.7% of the original P content could be extracted by boiling C6H6. Extraction with boiling 1:1 aqueous EtOH removed 78% of the P, and the extract was strongly acidic. The strongly acidic products formed during foam making were responsible for scorch. Heating 220 g. II at 150° for 105 hrs. under N gave 3 g. ClCH2CH2Cl (III). When 57.1 g. II and 15.9 g. N,N’-diphenylurea (IV) were heated at 150° under N for 48 hrs., the products isolated were III 17.6, 1,3-diphenyl-2-imidazolidone (m. 211-13°) 3.6, and N,N’-diphenylpiperazine (m. 165.5-7.6°) 5.4 g. The mechanism of the reaction rates of (BrCH2CH2CH2O)3P:O, I, Cl3CP(O)(OEt)2 (Kosolapoff, 1947), BrCH2CH2CH2P(O)(OEt)2 (prepared according to Eberhard, 1965), (ClCH2CHClCH2O)3P:O, and (BrCH2CHBrCH2O)3P:O with IV were compared. I was the least reactive. I showed greater hydrolytic stability than II and was less reactive toward bases. Foams were prepared using Daltocel SF polyester containing I or II and the fire-retardancy was similar according to ASTM D 1692-59T.
