Description
Calcium hydroxide, also known as slaked lime or hydrated lime, is a white powdery substance with the chemical formula Ca(OH)2. It is obtained by adding water to calcium oxide (quicklime), resulting in a process called slaking. Calcium hydroxide is slightly soluble in water and exhibits basic properties.
Uses
Used in Construction Industry:
Calcium hydroxide is used as a building material for its ability to improve the workability and durability of mortar and concrete. It reacts with carbon dioxide in the air to form calcium carbonate, which hardens and strengthens the structure over time.
Used in Agriculture:
In agriculture, calcium hydroxide is used as a liming material to neutralize acidic soils, thereby enhancing soil fertility and promoting plant growth.
Used in Chemical Research:
Calcium hydroxide is used as an intermediate in the production of various chemicals, such as calcium salts and detergents.
Used in Environmental Applications:
It is employed in water treatment processes to neutralize acidic wastewater and remove impurities, as well as in the flue gas desulfurization process to reduce sulfur dioxide emissions.
Used in Dolomite Production:
Calcium hydroxide is used in the production of dolomite, which is utilized for grain mounts, X-ray diffraction (XRD) and microprobe standards, and the identification of unknown minerals.
Used in Food Industry:
In the food industry, calcium hydroxide is used as a processing aid in the production of certain foods, such as tofu and other soy products, to improve their texture and quality.
Used in Pharmaceutical Industry:
Calcium hydroxide is used in the pharmaceutical industry as an ingredient in the preparation of various medications, including antacids and calcium supplements.
Used in Paper Manufacturing:
In the paper manufacturing process, calcium hydroxide is used as a pH regulator and a bleaching agent to improve the brightness and quality of the paper.
Check Digit Verification of cas no
The CAS Registry Mumber 12001-27-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,0 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 12001-27:
(7*1)+(6*2)+(5*0)+(4*0)+(3*1)+(2*2)+(1*7)=33
33 % 10 = 3
So 12001-27-3 is a valid CAS Registry Number.
