Latest Patents

Werner Ewald holds a patent for a process for producing calcium hydroxide. This process involves slaking finely divided or ground, softly burnt lime by blending it with a slaking liquid composed of 30 to 50 parts by volume water and 70 to 50 parts by volume organic solvent. The blending occurs at a temperature below 45 degrees Celsius in a mixing vessel. The reaction mixture is then transferred to a main reaction vessel, where it is heated to a temperature ranging from 50 to 70 degrees Celsius. The final reaction takes place in another vessel, ensuring that the ratio of lime to slaking liquid is optimized to achieve a final reaction temperature of 85 to 110 degrees Celsius.
