Abstract: Provided is an ionic liquid (IL) having anions and cations with a metalohydride in the IL of borohydrides and/or aluminum hydrides, as fuel and a choice of one or more oxidizers, which fuel and oxidizer have hypergolic tendencies.

Abstract: A hypergolic bipropellant. The hypergolic bipropellant includes a hydrazinium-based ionic liquid, a nitric acid-based oxidizer, and a catalyst.

Abstract: A hypergolic bipropellant. The hypergolic bipropellant includes an ionic liquid fuel and nitric acid, which is operable as an oxidizer. The ionic liquid fuel comprises an open chain amine having at least one quarternized nitrogen and a dicyanamide anion.

Abstract: Provided is a fuel of catalytic metal-containing ionic liquid (MCIL) and an IL, to spur hypergolic ignition of such liquids upon contact with an oxidizer to define a hypergolic bipropellant.

Abstract: Advanced bipropellant fuels with fast ignition upon mixing with storable oxidizer (N2O4, nitric acid) have been synthesized and demonstrated. The bipropellant fuels are based upon salts containing dicyanamide or tricyanomethanide anions and employ at least two hydrazine functionalities in the cations.

Abstract: Methods of preparing heterocyclic triazolium-based nitrate salts by a streamlined process are provided. Such salts offer energetic performance as well as pharmaceutical potential.

Abstract: The invention provides a high yield/isomerically pure synthesis of new 1-amino-3-substituted-1,2,3-triazolium salts and their subsequent transformation into isomerically pure 1-substituted-1,2,3-triazoles. These new 1-amino-3-substituted-1,2,3-triazolium salts are easily isolated and can be stored at ambient conditions with no degradation or isomerization. These quarternary salts are easily converted with appropriate silver salts to a wide array of new quarternary salts with various anions, with many of these new salts having melting points below 100 C, classifying them as ionic liquids. Subsequent diazotization of these 1-amino-3-substituted-1,2,3-triazolium salts results in high yields of isomerically pure 1-substituted-1,2,3-triazoles, that until this invention were problematic to make pure without tedious reagents or workup procedures.

Abstract: A ready-mixed (wet) joint compound comprising a filler, binder, thickener, non-leveling agent and sufficient water to afford a viscosity that renders the joint compound usable, the binder consisting essentially of a polyvinyl alcohol-stabilized vinyl acetate/ethylene polymer emulsion, 0.1 to 10 wt % polyethoxylated tallow amine and 0.1 to 10 wt % urea, the wt % being based on emulsion solids.
