20150299226 | TUNABLE METAL-ORGANIC FRAMEWORKS - A method, system, and apparatus for tunable metal-organic frameworks comprises a plurality of metallic ions, a plurality of organic linking anions that connect adjacent metallic ions of the plurality of metallic ions, and a plurality of cations connected to the plurality of organic linking anions, wherein the plurality of cations are selected from the group consisting of inorganic cations, organic cations, imidazolium based cations, pyridinium based cations, and cationic organic polymers and coordinated ligands. | 10-22-2015 |
20150065751 | Preparation of 4-Amino-2,4-Dioxobutanoic Acid - A first process for synthesizing 4-amino-2,4-dioxobutanoate involves reacting a dialkyl oxalate with an alkoxide in ethanol to form a reaction mixture, and afterward adding an alkyl cyanoacetate to the reaction mixture and allowing a reaction to proceed under conditions suitable to form a first reaction product of the formula diethyl 2-cyano-3-hydroxy-butenedioate, and then isolating the diethyl 2-cyano-3-hydroxy-butenedioate, and afterward reacting the diethyl-2-cyano-3-hydroxy-butenedioate with an aqueous hydroxide under conditions suitable to form 4-amino-2,4-dioxobutanoate. A second process for synthesizing 4-amino-2,4-dioxobutanoate involves reacting a dialkyl oxalate with an alkoxide in ethanol to form a reaction mixture, and afterward adding acetonitrile to the reaction mixture and allowing a reaction to proceed under conditions suitable to form a first reaction product in the form of an alkali salt of the formula ethyl 3-cyano-2-oxopropenolate, and then isolating the ethyl 3-cyano-2-oxopropenolate , and afterward either (a) reacting the ethyl 3-cyano-2-oxopropenolate with an aqueous hydroxide under conditions suitable to form 4-amino-2,4-dioxobutanoate; or (b) reacting the ethyl 3-cyano-2-oxopropenolate with hydrogen peroxide and ion exchange resin under conditions suitable to form 4-amino-2,4-dioxobutanoate. In these processes, the 4-amino-2,4-dioxobutanoate may be acidified into 4-amino-2,4-dioxobutanoic acid. | 03-05-2015 |
