摘要:A polynuclear complex of pullulan oligomers of formula (I): wherein n = (100-8200), obtained by process of synthesis of soluble pullulan with insoluble iron (III)-hydroxyde of formula (II): wherein n=(900). The process of synthesis is characterized by technical simplicity and economy. In accordance with suggested process, first of all, preparation of pullulan for synthesis, including its characterization (determination of RG, Mw, Mn, [θ]) is carried out, and subsequently its hydrogenation is carried out in order to eliminate reducing groups, iron(III)-hydroxyde gel is prepared, and synthesis of the complex can start. Obtained complex is afterwards prepared for pharmacological use and it is subjected to the subsequent physical and chemical processes of purification. The preparation obtained in such a way is used for prevention and treatment of syderopenic anemia in human and veterinay medicine.

摘要:An organo-template free method for the manufacture of a ferrierite (FER) zeolite and the ferrierite producible by the method. The method comprises (i) forming a reaction gel comprising an aluminium source, sodium and/or potassium hydroxide, and silica sol; and (ii) heating the reaction gel to a temperature and for a duration suitable for the growth of the FER zeolite. The reaction gel does not comprise seed crystals. Moreover the reaction gel does not comprise an organic structure directing agent (OSDA). The ferrierite (FER) zeolite has the following features: a) a SAR of between 11 and 20; b) a BET surface area of between 320 and 380 m 2 /g; and c) a micropore volume of between 0.1 and 0.2 cm 3 /g.

摘要:Synthesis of cationic-modified water-soluble polysaccharide is disclosed. The cation is pendent to the polysaccharide backbone. Chemical Mechanical Planarization (CMP) slurries comprise abrasives; activator; oxidizing agent; additive comprising cationic-modified water-soluble polysaccharide; and water. The use of the synthesized cationic-modified water-soluble polysaccharide in the CMP slurries reduces dishing and erosion in highly selective tungsten slurries.
