权利人:BURKES DOUGLAS E; MOORE JOHN J; AYERS REED A
摘要:A method for making high purity, multiphasic calcium phosphate powders using an Auto-Ignition Combustion Synthesis (AICS) reaction of a calcium salt, a phosphate salt and a fuel is provided. In the method provided, energy released from the AICS reaction between the calcium salt, phosphate salt and fuel ignites at temperatures much lower than the actual phase transformation temperatures and reaches a high temperature rapidly enough for synthesis of the desired product to occur, without the requirement for coprecipitation, an external heat source for calcination and/or additional steps for removing undesired precursors from the desired final product.

摘要:A preparation method of Cu—Pd—CeO 2 /γ-Al 2 O 3 @NP catalyst and a synthesis method of benzopyrazine compounds. The preparation method of the Cu—Pd—CeO 2 /γ-Al 2 O 3 @NP catalyst comprises the following steps: (1) preparing a CeO 2 /γ-Al 2 O 3 carrier; (2) preparing a CeO 2 /γ-Al 2 O 3 @NP carrier; (3) preparing the Cu—Pd—CeO 2 /γ-Al 2 O 3 @NP catalyst by impregnation method. A one-pot method for synthesizing benzopyrazine compounds of formula (III) includes using an o-nitroaniline compound of formula (I) and an aliphatic diol compound of formula (II) as raw materials, carrying out the one-pot synthesis of the benzopyrazine compound of formula (III) under solvent-free condition and under the combined action of the Cu—Pd—CeO 2 /γ-Al 2 O 3 @NP catalyst prepared by the method and an alkali. The Cu—Pd—CeO 2 /γ-Al 2 O 3 @NP catalyst increases the number of basic sites by doping N and P, and meanwhile loads CeO 2 to assist in the extraction of protons, thereby improving the dehydrogenation activity and product selectivity.

摘要:High-purity crystalline ferric phosphate material with desirable characteristics for use in synthesis of nano-sized LFP cathode material are described. The ferric phosphate dihydrate material has as disclosed herein has a molar ratio of phosphorous to iron is from about 1.001 to about 1.05, a surface area of from about 25 m 2 /g to about 65 m 2 /g, and is substantially free of metallic or magnetic impurities. Methods of synthesizing high-purity crystalline ferric phosphate material with desirable characteristics for use in synthesis of nano-sized LFP cathode material are also described. In some embodiments, one or more magnetic traps are used during the reaction process and/or after the formation of the final product to remove magnetic impurities. In some embodiments, a synthetic method of ferric phosphate using multiple steps is described, wherein the intermediate of the synthesis is isolated and purified to improve the purity of the ferric phosphate material. In some embodiments, an iron compound is added to an aqueous solution of phosphoric acid. The solution pH and temperature are controlled to ensure the complete dissolution of the iron compound. The desired iron phosphate crystalline material can be obtained with high purity and high crystalline phase purity by controlling the pH and temperature of the solution.
