Preparation of calcium hydroxide, a two - or polyhydric alcohol and a rich oil from plant- or animal origin, and its use for the collagen regenerationA pharmaceutical composition comprising calcium hydroxide, a vegetable or animal oil and optionally excipients contains a di- or polyhydric alcohol ...
of 5.8 in solution. The preparation contains 87 per cent protein and about 6 per cent sucrose. Details of the method (Indian patent application pending) as developed by us with the use of calcium hydroxide in sucrose will be published elsewhere later. We have been regularly producing in this...
Through specific surface area and thermo-gravimetric analysis, it was confirmed that the higher the specific surface area of calcium hydroxides, the higher their SO2 reactivity became. 展开 关键词: Calcium hydroxide Sorbent Hydration Organic coating Surface area SO2 reactivity DOI: 10.1016/...
Calcium hydroxide [Ca(OH)2] is one of the major constituents of hydrated portland cement paste. Its content can be used to trace the progress of cement hydration or serve as an indicator of the extent of pozzolanic reaction. The thermogravimetric analysis (TGA) method is often used to determi...

of an aqueous alkali metal hydroxide solution, which comprisesa) starting from a reaction mixture which has been obtained by reacting ascorbic acid with phosphorus oxychloride in the presence of pyridine while maintaining a pH of from 12 to 13 by means of an aqueous potassium hydroxide solution,<...
The aqueous hypochlorous acid solution may be prepared by chlorination of an alkaline compound (e.g. oxide, hydroxide or carbonate) of an alkali metal or alkaline earth metal. The solvent is preferably methyl ethyl ketone. Calcium hypochlorite may be prepared by (1) mixing lime with a solution...
The disordered crystals of calcium hydroxide exhibit better carbonation resulting in the large crystals of calcite; therefore, the mortar prepared from the lump lime has the highest flexural strength and compressive strength 0.8/2.5 MPa, its carbonation is the fastest and exhibits the longest ...
Selective formation of monodisperse spherical vaterite calcium carbonate (CaCO3) precipitate using glycine (Gly) in calcium hydroxide(Ca(OH)2)-Carbon dioxide (CO2) reaction system at room temperature and atmospheric pressure has been reported. Crystalline products were examined by scanning electron micros...
摘要: An improved 1-step process is disclosed for the preparation of thixotropic overbased calcium sulfonate complex thickened compositions containing calcium sulfonate as the dispersing agent and containing CaCO. sub.3 in the form of calcite crystals in colloidal or extremely finely divided form....
