Basic Information
Product Name: 1,2,3,4-Butanetetracarboxylic Acid
Molecular Formula: C8H10O8
CAS Number: 1703-58-8
Appearance: White crystalline powder or colorless crystals.
Solubility: Highly soluble in water (due to polar carboxyl groups); soluble in ethanol and acetone; poorly soluble in nonpolar solvents like benzene and diethyl ether.
Melting Point:~223-225°C (decomposes upon melting).
Acidity: A polyprotic strong acid with four stepwise dissociation steps. Approximate pKa values: pKa1≈1.6, pKa2≈2.0, pKa3≈4.5, pKa4≈5.5.
Applications
Polymer Industry
Crosslinker:
Used in thermosetting resins (e.g., unsaturated polyesters, alkyd resins) to improve mechanical strength and chemical resistance;
Enhances crosslinking efficiency in coatings, adhesives, and composites.
Polymer Modifier:
Introduces carboxyl groups into polymer chains to improve dyeability of polyester fibers or compatibility with polar additives.
Water Treatment
Chelates calcium and magnesium ions in hard water to prevent scaling in industrial pipelines or boilers.
Textiles and Dyeing
Chelates metal dyes or adjusts bath pH to promote dye fixation on cotton and synthetic fibers.
Pharmaceuticals and Agriculture
Pharmaceuticals: Acts as a ligand in drug synthesis or stabilizes metal-containing drugs;
Agriculture: Chelates trace elements (e.g., Fe, Zn) in fertilizers to enhance plant absorption.
Electroplating and Metal Processing
Controls metal ion concentration in electroplating baths for uniform coating deposition.
Safety and Handling
Hazards
Health Risks:
Skin/Eye Contact: Highly corrosive, causing severe burns or irritation;
Inhalation/Ingestion: Irritates respiratory and digestive systems, damaging mucous membranes.
Environmental Risks:
High water solubility may alter water pH and harm aquatic life if discharged untreated.
Safety Measures
Wear chemical-resistant gloves, goggles, and lab coats; operate in a fume hood.
Store in sealed containers, away from bases, oxidizers, and reducing agents.
In case of contact, flush with copious water; if ingested, seek medical help immediately (do not induce vomiting).
