摘要:Process for the preparation of nitride complexes of transition metals for use as radiopharmaceutical products or for the synthesis of novel pharmaceutical products. The process consists in reacting an oxygenic transition metal compound such as 99m Tc , 186 Re or 188 Re , with a first nitrogenous ligand such as sodium nitride or a nitrogenous compound such as S-methyl, N-methyl dithiocarbazate, and a reducing agent consisting of either tin (II) or a dithionite. The product so obtained can be used for the preparation of radiopharmaceutical products by a reaction with a second ligand such as sodium dithiocarbamate.

摘要:Synthesis gas is more effectively produced from the underground gasification of coal from a coal seam when the casing lining is cemented with a cementitious slurry containing a cementitious material, graphite and an aluminum silicate, such as metakaolin. The cementitious slurry of the cement mix sets as a cement sheath at bottomhole static temperatures less than or equal to 65° C. The set cement may withstand extreme dry heat temperatures which are greater than or equal to 800° C.

摘要:The present invention relates to a method for removing water from a compound solution and performing conjugate acid conversion. The method uses a nanometer film to perform reverse osmosis for the compound solution to remove water, and provides a conjugate acid to replace the acidic substances in the compound solution in order to obtain compound conjugate acid salts. The method of the present invention can effectively reduce the water content of the compound solution and replace the conjugate acid of the compound to form the desired compound conjugate acid salt.

摘要:Byproduct ammonium ions remaining in an aqueous solution of a water soluble glucoheptonate salt after its synthesis are reacted with the free acid form of a naphthalenesulfonic acid-formaldehyde condensation product to obtain an aqueous composition which does not produce an ammonia odor when introduced into aqueous media having a pH above 9. The aqueous composition can be dried to obtain a flowable powder. Both the aqueous composition and flowable powder are useful as additives in industrial products. They may be used to prolong the time of hydration of cement.
