Product Overview
Calcium oxide, commonly known as quicklime, is a highly reactive and versatile reagent-grade compound essential for laboratory applications requiring precise dehydration, pH regulation, or chemical synthesis. This reagent-grade calcium oxide is meticulously processed to ensure high purity, minimal impurities, and consistent performance in critical reactions. Its strong hygroscopic nature makes it ideal for moisture absorption, while its alkaline properties facilitate effective neutralization and pH adjustment in solutions. The fine, white powder dissolves rapidly in water, releasing heat and forming calcium hydroxide, a reaction leveraged in various analytical and preparative procedures. Due to its corrosive nature, proper handling with protective gear is recommended. Store in a tightly sealed container to prevent exposure to atmospheric moisture, which can compromise its reactivity. Whether used as a drying agent, a flux in metallurgy, or a reactant in organic synthesis, this calcium oxide delivers reliable results for demanding laboratory workflows.
FAQs
1. What is the shelf life of reagent-grade calcium oxide?
When stored in an airtight container away from moisture, reagent-grade calcium oxide retains its efficacy for up to 2 years. Exposure to humidity reduces its reactivity over time.
2. Can this calcium oxide be used for food-grade applications?
No, this is a reagent-grade product intended strictly for laboratory use. For food or pharmaceutical applications, food-grade calcium oxide with appropriate certifications is required.
3. How should I dispose of unused calcium oxide?
Neutralize with water to form calcium hydroxide (slaked lime), then dispose of according to local chemical waste regulations. Avoid direct disposal in dry form.
4. Is this calcium oxide compatible with glassware?
Yes, but prolonged contact with moisture can cause etching. Use borosilicate glass and rinse thoroughly after use to prevent damage.
5. What alternatives exist for dehydration reactions?
Silica gel, molecular sieves, or anhydrous magnesium sulfate are common alternatives, though calcium oxide is preferred for high-temperature or bulk moisture removal.
