摘要:
In accordance with one embodiment, a processing device includes a heated internal wall and a rotating rod positioned within an interior space formed by the heated internal wall. The rotating rod may be hollow and act as an internal heat exchanger. The processing device also includes a plurality of baffles spaced apart from one another along the rotating rod and extending away from the rotating rod towards the heated internal wall. The plurality of baffles or porous, packed basket that rotates with the rotating rod that also may be configured to provide cooling relative to the heated internal wall. The processing device also includes at least one wiper or roller coupled to an edge of at least one of the plurality of baffles or porous, packed basket, coupled to the rotating rod and that contacts the heated internal wall while rotating together with the rotating rod. In another embodiment, a processing device may be used to adsorb reactive gases into a liquid phase while heat is exchanged.
摘要:
Novel catalysts capable of rendering both polar and non-polar organic fuels hypergolic with rocket-grade hydrogen peroxide are disclosed. These catalysts are complexes formed by reacting alkyl-substituted diamines or triamines, with metal salts of an aliphatic carboxylic acid or metal 1, 3-dione chelates. In addition, the use of various acetylenic compounds as stability enhancing additives and/or promoters is described.

A process for extracting secoisolariciresinol doglycoside (SDG) from de-fatted flaxseed is described. The process comprises contracting defatted flaxseed with an extraction solvent of acetone and water, extracting the de-fatted flaxseed with the extraction solvent to extract SDG-containing compounds, removal pf solvents, followed by alkaline hydrolysis of the extract to liberate free SDG or its salts.
摘要:
A process is described for efficiently recovering at least one of phytosterols and tocopherols in substantially pure form from the deodorizer distillates that may be obtained as by-products of the refining of edible oils. The phytosterol fatty acid esters present in deodorizer distillate are saponified with potassium hydroxide in a solvent medium containing methanol and water, thereby forming a solvent medium containing methanol, water, and the potassium soaps of fatty acids. Unsaponiable matter including tocopherols remain dissolved in this medium, allowing recovery of substantially pure phytosterols. Tocopherols in substantially pure form may be recovered by distillation under reduced pressure.
摘要:
Dietary mineral supplements comprising the calcium and/or magnesium salts of 3-hydroxy-3-methylbutyric acid are disclosed as efficient means of orally administering calcium and /or magnesium in order to prevent or treat calcium and magnesium deficiency pathologies. The conjoint bioavailability of these important minerals is thereby enhanced.
摘要:
Tri- and tetra-substituted ethynylsilanes wherein the substituents are higher homologs of acetylene (e.g., substituted-ethynyl moieties having 3 to 10 carbon atoms) are described. Alkynylsilanes and, more particularly, high energy fuels and rocket propellants containing an alkynylsilanes are also provided.
