Product Description

Product Description

Manganese Acetate (Manganese(II) Acetate) Product Introduction

Manganese Acetate, specifically Manganese(II) Acetate (CAS No. 638-38-0 for the anhydrous form, 6156-78-1 for the tetrahydrate), is an important inorganic salt. It typically appears as a pale pink solid (tetrahydrate) or a white powder (anhydrous). It is highly soluble in water and widely used as a catalyst, drying agent, and precursor for other manganese compounds.

Physical and Chemical Properties

1. Physical State:
   • Tetrahydrate: Pale pink monoclinic crystals (most common commercial form).
   • Anhydrous: White powder.
2. Odor: Slight acetic acid odor.
3. Density: 1.589 g/cm³ (tetrahydrate).
4. Melting Point: 80°C (tetrahydrate, loses water); 280°C (anhydrous, decomposes).
5. Solubility: Highly soluble in water (140 g/100 mL at 20°C). Also soluble in ethanol and glacial acetic acid.
6. pH: Acidic (5% aqueous solution has a pH of 4-5).
7. Stability: Stable under normal conditions. Hygroscopic; the anhydrous form readily absorbs moisture from the air to form the tetrahydrate.

 

Main Applications

1. Catalyst:
   • Paints and Coatings: It is a key component in the production of "siccatives" (drying agents) for oil-based paints and varnishes. It accelerates the oxidation and polymerization of drying oils (e.g., linseed oil).
   • Chemical Synthesis: Used as a catalyst in the oxidation of paraffins, the polymerization of olefins, and the synthesis of vinyl acetate.
    
2. Textile Industry:
   • Used as a mordant in dyeing and printing textiles, especially for attaching dyes to cotton and linen fibers.
   • Used in the production of manganese dioxide for battery cathodes.
    
3. Agriculture:
   • Used as a micronutrient fertilizer to correct manganese deficiency in crops (e.g., cereals, fruits, vegetables).
    
4. Laboratory and Chemical Manufacturing:
   • A common precursor for the synthesis of other manganese compounds (e.g., manganese dioxide, manganese carbonate).
   • Used in analytical chemistry as a reagent.
    
5. Other Uses:
   • Component in wood preservatives.
   • Used in the leather tanning process.
    

Performance Characteristics

 

1. Drying Efficiency: Excellent catalytic activity for promoting the drying of alkyd resins and drying oils.
2. Solubility: Its high solubility in water and organic solvents allows for easy formulation into liquid products.
3. Color Stability: While it is pink, it typically does not impart a strong color to the final dry paint film (unlike cobalt driers, which can cause discoloration).

 

Safety, Handling, and Storage

 

1. Health Hazards:
   • Irritation: May cause skin and eye irritation.
   • Inhalation: Dust may irritate the respiratory tract.
   • Ingestion: Harmful if swallowed. Excessive exposure can lead to manganese poisoning (manganism), affecting the central nervous system, but this is typically associated with chronic inhalation of dust/fumes, not casual handling.
    
2. Fire Hazards: Not flammable.
3. Personal Protective Equipment (PPE):
   • Wear protective gloves (latex or nitrile), safety goggles, and a dust mask.
   • Wash hands thoroughly after handling.
    
4. Storage:
   • Store in a cool, dry, well-ventilated area.
   • Keep containers tightly closed to prevent moisture absorption (hygroscopic nature).
   • Incompatibility: Do not store near strong oxidizing agents or strong bases.
