Distillation of Calcium Acetate

Calcium acetate is a calcium salt of acetic acid with the chemical formula Ca(CH3COO)2. When it is dry distilled, it undergoes thermal decomposition and gives various products. Let's understand the process and products obtained during the dry distillation of calcium acetate.

Process of Dry Distillation

Dry distillation is a process in which a substance is heated to a high temperature in the absence of air or oxygen. When calcium acetate is heated to a high temperature, it undergoes thermal decomposition, and different products are obtained. The products depend on the temperature at which the dry distillation is carried out.

Products Obtained During Dry Distillation

Calcium acetate when dry distilled gives the following products:

1. Acetone

Acetone is an organic compound with the chemical formula (CH3)2CO. It is a colorless, volatile, and flammable liquid that is used as a solvent and in the production of various chemicals. Acetone is obtained during the dry distillation of calcium acetate at a temperature of 350-400°C.

2. Carbon Dioxide

Carbon dioxide is a colorless, odorless gas with the chemical formula CO2. It is a greenhouse gas that is responsible for global warming. Carbon dioxide is obtained during the dry distillation of calcium acetate at a temperature of 400-500°C.

3. Calcium Oxide

Calcium oxide is a white, caustic, and alkaline solid with the chemical formula CaO. It is also known as quicklime and is used in the production of cement, steel, and other chemicals. Calcium oxide is obtained during the dry distillation of calcium acetate at a temperature of 500-600°C.

4. Calcium Carbonate

Calcium carbonate is a white, insoluble, and alkaline solid with the chemical formula CaCO3. It is a common mineral that is found in rocks and shells. Calcium carbonate is obtained during the dry distillation of calcium acetate at a temperature of 600-700°C.

Conclusion

Calcium acetate when dry distilled gives various products depending on the temperature at which the distillation is carried out. Acetone is obtained during the dry distillation of calcium acetate at a temperature of 350-400°C. Therefore, the correct answer is option 'C'.
