PRIORITY: US 1995-504855 20 Jul 1995. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Polyurethane foams are prepd. using 31 metal acetylacetonate and acetylacetone in which a urethane mixt. and catalyst is heated to a temp. at which the acetylacetone inhibitor is driven off and the formation of polyurethane is accelerated. This method provides control of the catalyst at higher temps. suitable for foam processing. In an example, a foam was prepd. from Arco 34-45, UC 0200, dipropylene glycol, and Isonate 143L using Fe(III) acetylacetonate and acetylacetone. .

Stability of: Stability of .beta.-diketonates of alkaline earth metals in water-dioxane solutions. Jablonski, Zygfryd; Wasag, Tadeusz; Millo, Selim (Inst. Fundam. Chem., Polytech. Szczecin, Szczecin, Pol.). Rocz. Chem., 50(9), 1467-72 (English) 1976. CODEN: ROCHAC. DOCUMENT TYPE: Journal CA Section: 68 (Phase Equilibriums, Chemical Equilibriums, and Solutions) The compn. and stability consts. were detd. for Be, Mg, Ca, Sr, and Ba chelate compds. with acetylacetone, benzoylacetone, dibenzoylmethane, and thenoyltrifluoroacetone. The detns. were carried out by potentiometric titrn. in water-dioxane solns. The 1st stage in formation of the chelates was a monopos. cation with a chelate ring, follwed by attachment of the 2nd ligand and formation of a 2-ring neutral complex.There are some commonly used reagents with their cas registry numbers 12084-29-6 and 67860-63-3 in this article. The highest stability was obsd. for Be diketonates. For a given element the stability increased with increasing no. of Ph groups in the .beta.-diketone involved. .
