Basic Information
Product Name: 1,6-Hexanediamine Hydrochloride
Molecular Formula: C6H16N2.2HCl
Molecular Weight: 189.13 g/mol
CAS Number: 6055-22-9
Physical and Chemical Properties
Appearance: White crystalline powder or granules; odorless or with a faint amine-like smell (may release trace ammonia if decomposed).
Physical Parameters:
Melting Point: ~220-225°C (decomposes)
Solubility: Highly soluble in water (forms acidic solutions); slightly soluble in ethanol; insoluble in organic solvents like ether or benzene.
pH of Aqueous Solution: Acidic (pH < 7, due to hydrochloric acid dissociation).
Chemical Properties:
A diacid salt formed by the reaction of 1,6-hexanediamine (a strong base) with hydrochloric acid.
Stable under normal conditions but may react with strong bases (e.g., NaOH) to liberate free hexanediamine.
Hygroscopic (absorbs moisture from air), so storage in dry conditions is essential.
Primary Applications
(1) Polymer Industry
Polyamide Synthesis (Nylon Precursor):
Reacted with dicarboxylic acids (e.g., adipic acid) to produce nylon 6,6 via condensation polymerization.
The hydrochloride salt is first converted to free hexanediamine by neutralization with bases (e.g., NaOH) before use in nylon production.
Curing Agent for Epoxy Resins:
Sometimes used as a latent curing agent (after dehydrochlorination) in epoxy formulations, though free amine is more common.
(2) Pharmaceutical and Chemical Intermediates
Drug Synthesis:
As a building block in synthesizing pharmaceuticals (e.g., antihistamines, local anesthetics) due to its diamine structure.
Electroplating:
In acidic plating baths as a complexing agent or pH buffer.
(3) Corrosion Inhibitors
Oil and Gas Industry:
Converted to amine-based inhibitors for metal surfaces in acidic environments (after neutralization).
(4) Laboratory and Research
Reagent in Organic Synthesis:
Used in the preparation of diamine derivatives, Schiff bases, or as a catalyst in certain condensation reactions.
Safety and Handling
Toxicity:
Low acute toxicity (oral LD50 in rats: >2000 mg/kg), but solutions are corrosive to skin and eyes due to acidity.
Inhalation of dust may irritate the respiratory tract; ingestion may cause gastrointestinal discomfort.
Hazard Class: Corrosive (due to HCl content); labeled as Xi (Irritant) in EU CLP regulations.
Handling Precautions:
Wear protective gloves, goggles, and a lab coat.
Avoid contact with skin, eyes, or mucous membranes. In case of contact, flush thoroughly with water.
Store in tightly sealed containers in a cool, dry place, away from bases and oxidizing agents.
Spill Management: Sweep up dry powder or neutralize spills with baking soda before disposal (follow local regulations).
Storage and Stability
Storage Conditions:
Keep in airtight containers to prevent hygroscopicity and reaction with atmospheric moisture or bases.
Avoid exposure to strong bases (e.g., NaOH, KOH), which can liberate ammonia and free amine.
Shelf Life: Stable for 2-3 years if stored properly.
