Chemical Name: Tetradecane
Chemical Formula: C14H30
Common Names: n-Tetradecane, normal Tetradecane
Appearance: Clear, colorless liquid
Odor: Mild, petroleum-like
Molecular Weight: 198.39 g/mol
Use: Labs and industry often turn to tetradecane as a solvent, calibration standard, and specialty chemical, especially in hydrocarbon analysis and as a reference material.
Hazard Class: Flammable Liquid
Health Risks: Inhalation or skin contact can irritate but doesn’t usually cause severe injury; swallowing larger amounts can upset the stomach and nervous system
Explosion Risk: Vapors can ignite if there’s a spark and enough of them in the air
Symbols: Flammable liquid pictogram usually applies, with warnings for environmental risk
Routes of Exposure: Breathing in mist or vapors, skin or eye contact, swallowing
Symptoms: Shortness of breath, coughing, headache, dizziness, gastrointestinal upset if swallowed, mild eye and skin irritation, drowsiness after strong exposure
Ingredient: Tetradecane
CAS Number: 629-59-4
Purity: Most industrial batches run at 98% or higher
Impurities: Trace alkanes of other chain lengths sometimes show up, along with minor amounts of unsaturated hydrocarbons produced in processing
Inhalation: Fresh air matters first, ideally move the person outside and loosen tight clothing; if breathing trouble starts, medical help makes the difference
Skin Contact: Clean, running water and mild soap, rinse for at least fifteen minutes, take off contaminated clothes
Eye Contact: Flush eyes right away with lukewarm water, keep eyelids open and roll eyes gently
Swallowing: Never make someone vomit if tetra-decane got down the hatch, rinse mouth, go for medical help soon, avoid giving them food or drink unless a medical pro says it’s all right
Suitable Extinguishers: Use foam, dry chemical, or carbon dioxide — water can spread burning liquid
Fire Hazards: Gives off vapors heavier than air that can travel and ignite far from the source, burns with a smoky flame though not explosively
Special Instructions: Wear full protective gear and self-contained breathing apparatus; cool tanks and drums with water spray to prevent rupture
Byproducts: Burning can release toxic fumes including carbon monoxide, soot, and unburned hydrocarbons
Containment: Block off spill area, stop leaks if possible without taking risks; use barriers around storm drains to keep it out
Spill Cleanup: Absorb with earth, sand, or other inert material; transfer waste to proper containers for later disposal
Ventilation: Open windows and doors, set up fans, keep air moving if safe to do so
Personal Protection: Wear gloves, eye protection, and if levels get high, a respirator
Environmental Protection: Avoid letting tetradecane run off into streams, lakes, or the soil; even though it’s considered slow to break down, large releases still threaten aquatic life and groundwater
Handling: Only handle tetradecane where there’s clear air flow; keep it away from open flames, electrical sparks, and sources of static; don’t eat, drink, or smoke anywhere it’s used
Storage: Keep it in tightly sealed containers made of steel or compatible plastics, out of the sun and away from heat
Incompatible Materials: Strong oxidizers, acids, halogens; avoid storing it with reactive chemicals that could trigger a fire or release dangerous gases
Labeling: Mark all containers clearly so nobody gets careless or accidentally mixes it with the wrong chemicals
Ventilation: Good exhaust fans prevent buildup of air concentrations above safe levels
PPE: Gloves made of nitrile or neoprene, chemical splash goggles, long-sleeve work clothing
Respiratory Protection: If air tests show higher than recommended exposure, wear an organic vapor respirator
Hygiene: Wash hands after handling, keep contaminated items away from food and drink, don’t bring home used work clothes
Monitoring: On-site tests for vapor levels make a real difference, especially in confined spaces
Physical State: Liquid at room temperature
Color: Colorless
Odor Threshold: Fairly low, slight petroleum smell
Boiling Point: Around 253°C
Melting Point: About 5.9°C
Vapor Pressure: Low at room temperature
Flash Point: Near 100°C, so not the kind of liquid people want near welding torches or hot machinery
Solubility: Does not dissolve in water; mixes well with other organic solvents
Stability: Stays stable under normal storage and handling
Reactivity: Can react with powerful oxidizing agents or acids, which brings risk of rapid burning or dangerous fumes
Hazardous Byproducts: Heat, flame, or strong chemicals can break tetradecane down into carbon monoxide, smoke, and other hydrocarbons
Acute Effects: Breathing high vapor levels of tetradecane for too long in closed rooms might cause headaches, drowsiness, nausea, and lightheadedness
Skin Contact: Frequent exposure removes natural oils, leading to dryness, redness, or mild dermatitis
Chronic Exposure: Long-term, routine contact could increase the risk for minor nervous system effects, though research on lasting harm stays inconclusive
Carcinogenic Status: Current studies do not single out tetradecane as a known carcinogen
Other Health Facts: No hard evidence ties tetradecane to birth defects or reproductive issues, reinforced by animal testing
Environmental Fate: Tetradecane evaporates slowly from soil but breaks down mostly by natural bacteria over weeks or months in open air
Aquatic Impact: Insoluble in water, floats and forms slicks if spillage occurs, harms fish and water bugs because it blocks oxygen exchange and can gunk up gills or other body surfaces
Persistence: While not extremely long-lived, can linger in contaminated groundwater or shoreline sand after large spills
Waste Management: Never pour tetradecane down the drain or into soil; used material should head to approved facilities for chemical disposal
Empty Containers: Even small leftovers in drums or bottles can pose fire hazards, so rinse or treat as hazardous until professionally cleaned
Community Responsibility: People handling waste should verify the site’s license to deal with organic solvents and follow local environmental rules closely
Regulatory Status: Tetradecane falls under flammable liquid rules for trucks, trains, and ships
Packing: Uses sealed steel cans or high-density plastic drums, always protected against leaks with secondary containment
Risks in Transit: Main dangers trace back to spills leading to road or river contamination, or fires set off by accidents at loading sites
Emergency Response: Crews trained in flammable liquid spills rely on foam and specialized barriers, not water jets, to contain fires or leaks
Workplace Exposure Limits: No strict federal exposure limits for tetradecane alone, though similar aliphatic hydrocarbons do have recommended limits
Labeling: Shipped and stored with flammable liquid warnings and hazard symbols as prescribed by bodies such as OSHA and EU-GHS
Documentation: Any large users or traders must keep material transfer and storage records, follow shipping laws on placards and emergency procedures, and carry out regular safety training
