Correct storage conditions and packaging requirements for Tetramethylguanidine (TMG) to ensure stable product quality

Introduction

Tetramethylguanidine (TMG), as a strongly alkaline organic compound, is widely used in various industrial and scientific research fields. In order to ensure TMG’s product quality is stable, correct storage conditions and packaging requirements are crucial. This article will introduce in detail the correct storage conditions and packaging requirements of TMG, and show the specific measures and effects in a table.

Basic properties of tetramethylguanidine

  • Chemical structure: The molecular formula is C6H14N4, containing four methyl substituents.
  • Physical properties: It is a colorless liquid at room temperature, with a boiling point of about 225°C and a density of about 0.97 g/cm³. It has good water solubility and organic solvent solubility.
  • Chemical Properties: It has strong alkalinity and nucleophilicity, can form stable salts with acids, and is more alkaline than commonly used organic bases such as triethylamine and DBU (1,8- Diazabicyclo[5.4.0]undec-7-ene).

Storage conditions of tetramethylguanidine

1. Temperature control
  • Temperature range: TMG should be stored in a cool, dry environment, and the temperature should be controlled between 10-25°C. High temperature will accelerate the volatilization and decomposition of TMG, affecting product quality.
  • Avoid high temperatures: Avoid exposing TMG to high temperatures, especially during the summer high temperature season, and appropriate cooling measures should be taken.
Storage conditions Specific requirements Reasons
Temperature range 10-25°C High temperature will accelerate volatilization and decomposition, affecting product quality
Avoid high temperatures Avoid exposure to high temperatures High temperatures may cause volatilization and decomposition
2. Humidity control
  • Humidity range: TMG should be stored in an environment with a relative humidity of less than 70%. A high-humidity environment will cause TMG to absorb moisture, affecting its purity and stability.
  • Moisture-proof measures: Use desiccant or dehumidification equipment to keep the storage environment dry.
Storage conditions Specific requirements Reasons
Humidity range Relative humidity < 70% High humidity environment will cause moisture absorption, affecting purity and stability
Moisture-proof measures Use desiccant or dehumidification equipment Keep the storage environment dry
3. Store away from light
  • Light protection requirements: TMG should be stored in a light-proof environment and avoid direct sunlight. Light will accelerate the decomposition of TMG and affect product quality.
  • Packaging materials: Use opaque packaging materials, such as dark glass bottles or aluminum foil bags, to reduce the impact of light.
Storage conditions Specific requirements Reasons
Light protection requirements Store in a dark environment Light will accelerate decomposition and affect product quality
Packaging materials Use opaque packaging materials Reduce the impact of light
4. Good ventilation
  • Ventilation requirements: The environment where TMG is stored should be well ventilated to avoid accumulation of volatile TMG gas and affect the health of operators.
  • Ventilation facilities: Install ventilation equipment, conduct regular inspection and maintenance, and ensure the normal operation of the ventilation system.
Storage conditions Specific requirements Reasons
Ventilation requirements Maintain good ventilation Avoid the accumulation of volatile gases and affect the health of operators
Ventilation facilities Install ventilation equipment, conduct regular inspection and maintenance Ensure ventilation system is functioning properly
5. Avoid contact with acidic substances
  • Isolation requirements: TMG should be stored away from acidic substances to avoid chemical reactions that may affect product quality.
  • Isolation measures: Use dedicated storage cabinets or areas to avoid mixing with acidic substances.
Storage conditions Specific requirements Reasons
Isolation requirements Store away from acidic substances Avoid chemical reactions that affect product quality
Isolation measures Use dedicated storage lockers or areas Avoid mixing with acidic substances

Packing requirements for tetramethylguanidine

1. Packaging materials
  • Container material: Use corrosion-resistant and well-sealed containers, such as glass bottles, stainless steel cans or plastic barrels. Avoid using materials that may react with TMG.
  • Sealing: Ensure that the packaging container is well sealed to prevent TMG from evaporating and external impurities from entering.
Packaging requirements Specific measures Reasons
Container material Use glass bottles, stainless steel cans or plastic buckets Avoid encounters with TMGReaction
Tight sealing Make sure the packaging container is tightly sealed Prevent volatilization and external impurities from entering
2. Packaging specifications
  • Packaging specifications: Choose the appropriate packaging specifications according to actual needs, such as 500 mL, 1 L, 5 L, 20 L, etc. Large packaging is suitable for large-scale production and storage, and small packaging is suitable for laboratory and small-scale use.
  • Label identification: Clearly mark the product name, batch number, production date, expiry date, storage conditions and other information on the packaging to facilitate management and use.
Packaging requirements Specific measures Reasons
Packaging specifications Choose appropriate packaging specifications Meet different usage needs
Tag ID Clearly label product information Easy to manage and use
3. Transportation requirements
  • Shipping container: Use a dedicated shipping container to ensure no leakage or damage during transportation.
  • Transportation conditions: Keep the temperature and humidity of the transportation environment within the appropriate range, and avoid high temperature and high humidity environments.
  • Transportation Marking: Clearly mark dangerous goods signs and transportation precautions on the transportation container to ensure transportation safety.
Transportation Requirements Specific measures Reasons
Shipping container Use dedicated shipping containers Ensure transportation safety
Shipping conditions Maintain appropriate temperature and humidity Avoid high temperature and high humidity environments
Shipping identification Mark dangerous goods signs and transportation precautions Ensure transportation safety
