- PROCESS FOR PREPARING A METAL-ORGANIC FRAMEWORK
-
The present invention relates to a process for preparing a magnesium formate based metal-organic framework. The process comprises (a) combining magnesium or magnesium oxide with formic acid; (b) heating the reaction mixture of step (a) at a temperature of between 70°C and 200°C; (c) combining formic acid with the reaction mixture of step (b); and (d) heating the reaction mixture of step (c) at a temperature of between 70°C and 200°C. Steps (c) and (d) may be heated up to 5 times.

- METHOD OF PRODUCING ALCOHOLS
-
A method of making alcohols involves forming of alcohol esters from liquid alkane halides and a solution of metallic salts of organic acids to produce gaseous alcohol esters for reaction with magnesium or metal hydroxides to form the alcohol and the metal salt of the organic acids. In an improvement method, liquid phase alcohol esters instead of gaseous alcohol esters are produced from liquid alkane halides and a solution of metal salts of organic acids whose alkane esters are less soluble in water than that of the alkane halide and treating of the alcohol ester formed with magnesium or metal hydroxides to form the alcohol and the metal salt of the organic acids.

- CO2-"Neutral" hydrogen storage based on bicarbonates and formates
-
Let the circle be unbroken! One ruthenium catalyst generated in situ facilitates the selective hydrogenation of bicarbonates and carbonates, as well as CO2 and base, to give formates and also the selective dehydrogenation of formates back to bicarbonates. The two reactions can be coupled, leading to a reversible hydrogen-storage system. dppm=1,2- bis(diphenylphosphino)methane. Copyright

- PROCESS FOR MANUFACTURE OF CARBOXYLIC ACID SALTS
-
The invention relates to a process for manufacture of carboxylic acid salts in the form of alkali metal or alkaline-earth metal carboxylates of 1 to 3 carbon atoms. The continuous manufacturing process comprises: 1) passing carboxylate salt of a starting cation through one or several ion exchange beds containing solid cation exchanger charged with an alkali metal or alkaline-earth metal cation,2) collecting a product solution containing alkali metal or alkaline-earth metal carboxylate eluted from the one or several ion exchange beds in step 1,3) simultaneously with step 1, regenerating one or several ion exchange beds containing solid cation exchanger charged with the starting cation by passing a regenerating solution containing a salt formed by an anion and the alkali metal or alkaline-earth metal cation through the one or several ion exchange beds,4) collecting an effluent solution containing the starting cation and the anion eluted from the one or several ion exchange beds in step 3, and 5) shifting the inlet and outlet points of the solutions in the same direction to other ion exchange beds._________________________________________________________

- Measurement of equilibrium water vapor pressures for the thermal dehydrations of some formate dihydrates by means of the transpiration method
-
The equilibrium water vapor pressures, PH2O for the thermal dehydrations of some formate dihydrates, M(HCO2)2·2H2O, where M is Mg, Mn, Co, Ni and Zn, were measured by means of the transpiration method using a laboratory-made apparatus. These hydrates have a monoclinic isomorphous crystal structure with a space group, P21/C. The thermodynamic data such as ΔG, ΔH and ΔS for the dehydration were derived from the PH2O and correlated to the crystal structures of these hydrates. Although the values of ΔH were expected to increase in the order of the hydrates of Mn2+-OH2 bond, they increased in the order of Mn2)2·2H2O and Zn(HCO2)2·2H2O seemed to be due to the relatively strong hydrogen bond between the water molecules and the formate ions. The values of ΔG obtained at 373 K, ΔG(373) showed a good correlation with the beginning temperatures of the dehydrations, Ti.
