Proper storage of Diethyl Oxalate is crucial for workplace safety and product integrity. As a key organic chemical widely used in pharmaceutical and industrial applications, this ester requires specific handling conditions to maintain stability. This guide provides essential safety protocols for procurement professionals dealing with Diethyl Oxalate, covering optimal storage temperatures, container materials, and environmental controls to prevent degradation or hazardous situations.

Understanding Diethyl Oxalate Properties

Diethyl Oxalate (C6H10O4) is an organic compound with ester functional groups, widely utilized as a solvent and intermediate in pharmaceutical synthesis. Its molecular structure makes it sensitive to moisture and temperature fluctuations. Key characteristics include:

• Molecular Weight: 146.14 g/mol
• Boiling Point: 185-186°C
• Flash Point: 75°C (closed cup)
• Solubility: Miscible with alcohol and ether, reacts with water

These properties dictate stringent storage requirements. For procurement specialists handling similar compounds like Ethylene glycol monomethyl ether (a versatile solvent with 163.5°C boiling point), understanding material compatibility is equally critical.

Optimal Storage Conditions

Maintaining Diethyl Oxalate quality requires controlled environmental parameters:

Temperature Control

Store between 15-25°C in climate-controlled warehouses. Prolonged exposure to temperatures above 30°C accelerates decomposition, while freezing may cause crystallization. Industrial-grade refrigeration units should maintain ±2°C stability.

Humidity Management

Relative humidity must stay below 45% to prevent hydrolysis. Use desiccant packs in storage containers and install humidity monitors with alarms. This parallels storage protocols for moisture-sensitive solvents like Ethylene glycol monomethyl ether, where purity ≥99% demands similar precautions.

Container Selection Guidelines

Proper packaging prevents contamination and extends shelf life:

Always verify container compatibility through material safety data sheets (MSDS). For reference, our 200kg galvanized iron drum packaging for glycol ether products undergoes rigorous leakage testing.

Safety Protocols for Handling

Implement these measures to mitigate risks:

1. Ventilation: Ensure storage areas have 6-12 air changes/hour
2. Spill Control: Keep acid-neutralizing absorbents (vermiculite or sand) nearby
3. PPE Requirements: Nitrile gloves + chemical goggles for handling
4. Fire Prevention: Class B fire extinguishers within 10m radius

Regular staff training should include emergency response drills and proper disposal procedures per local regulations.

Inventory Management Best Practices

Streamline procurement operations with these strategies:

• Implement FIFO (First-In-First-Out) rotation to prevent aging
• Maintain batch tracking with QR code labeling
• Conduct quarterly integrity checks for container corrosion
• Keep stock levels below 70% capacity to allow for proper air circulation

These measures align with ISO 9001 quality management standards, similar to our production protocols for alcohol series products.
