摘要:The present disclosure provides a preparation method for hydrothermal synthesis of fly ash silicate aggregate including: mixing sodium metasilicate, potassium hydroxide, and inorganic-organic hybrid excitation monomer as raw materials to obtain an inorganic-organic composite activator; preparing a silicate aggregate raw material, mixing measured fly ash, carbide slag, quicklime, and vitrified micro bubble by mass, adding the inorganic-organic composite activator and continue stirring to produce a mixture; forming a ball disc, wetting an expanded perlite that forms a core of the ball by spraying water, adding a prepared mixture, spraying water while adding, standing and curing, performing a maturation and activation treatment in an autoclave, undergoing a silicon calcium reaction for a hydrothermal synthesis to obtain the silicate aggregates. The present disclosure obtains silicate aggregates with high-performance by accelerating an internal activity of fly ash at an early stage and fully activating the activity of fly ash in all process.

权利人:Monroe Mary Beth; PETRYK NATALIE M
摘要:A degradable polyurethane (PUr) having degradation rates useful for hemostatic dressings for controlling bleeding in traumatic wounds. Degradable PUrs may be synthesized from degradable monomers based on hydrolytically labile esters and oxidatively labile thioethers using rapid click-chemistry reactions. Monomers may include trimethylolpropane tris(3-mercaptopropionate) (TMPMP), dipentaerythritol hexakis(3-mercaptopropionate) (DPEHMP), dipentaerythritol hexakis(3-mercaptopropionate) (DPEHMP) or 2,2'-(ethylenedioxy) diethanethiol reacted with hydroxyethyl acrylate, 3-buten-1-ol, 3-methyl-3-buten-1-ol, or 3-buten-2-ol. Synthesis of these monomers is rapid and has no byproducts or toxic catalysts that require removal, enabling polyol synthesis and immediate use in further polymerization

摘要:The present invention provides unified synthesis of the C1-C19 building blocks of halichondrins and analogs thereof using selective coupling of poly-halogenated nucleophiles in chromium-mediated coupling reactions. The present invention also provides a practical and efficient synthesis of C20-C38 building blocks of halichondrins and analogs thereof. Also provided herein are general methods of selective activation and coupling of poly-halogenated analogs with an aldehyde. The provided coupling reactions are selective for halo-enone and halo-acetylenic ketal over vinyl halide and halide attached to a sp hybridized carbon. The provided efficient selective coupling reactions can allow easy access to the C1-C19 building blocks and C20-C38 building blocks of halichondrins and analogs thereof with limited or no purification or separation of the intermediates.
