Chemical Name: S-Butyl Acetate
CAS Number: 105-46-4
EC Number: 203-300-1
Commercial Synonyms: sec-Butyl acetate
Physical Appearance: Colorless, flammable liquid with a fruity odor
As producers, S-Butyl Acetate runs in many of our batch processes. You notice its signature odor before you see it, so we always keep tabs on ventilation where this ester is present. All of our labels show clear chemical names and hazard pictograms, giving teams that extra moment of caution with each drum or tank transfer.
GHS Classification: Flammable Liquid, Eye Irritant, Narcotic Effects
Major Hazards: Easily ignites, vapors tend to collect in low-lying areas, heavy inhalation can cause dizziness or headaches
Signal Words: Danger
We respect that vapors from S-Butyl Acetate can cause fire if not respected, so our plants carry out regular inspections for leaks and proper grounding of equipment. Employees who have spent years at our sites learned quickly that quick fixing a loose fitting is never an option with volatile liquids.
Component: sec-Butyl Acetate
Concentration: 99% or higher
Key Impurities: Minimal byproducts from esterification remain far below regulatory thresholds
Our reaction units and refining systems are locked into specific parameters to keep byproduct formation extremely low. We confirm purity in every lot before filling tanks for delivery. This keeps performance reliable at the next customer process and limits the introduction of unwanted reactivity downstream.
Inhalation: Remove immediately to fresh air, keep person calm and warm
Eye Contact: Rinse thoroughly with plenty of water for at least 15 minutes, seek medical advice
Skin Contact: Remove contaminated clothing and shoes, wash skin with soap and water
Ingestion: Rinse mouth, do not induce vomiting, get medical help immediately
Operators working onsite are trained yearly on these practical responses. Anyone exposed faces rapid escalation to the medic, not to their own devices. Everything from safety showers to eye-wash stations sees regular checks and drills, so our people know their way even when alarm bells are sounding.
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical, carbon dioxide
Specific Hazards: Highly flammable vapor-air mixtures, explosive risk in confined spaces
Special Protective Equipment: Full turnout gear and self-contained breathing apparatus
We only allow trained responders near a flaming vessel. Site protocols prohibit water jets because they spread burning liquid. The response is always coordinated with local emergency services, and our internal teams drill alongside them to make sure we all speak the same language in a crisis.
Personal Precautions: Evacuate unnecessary personnel, ventilate area, eliminate ignition sources
Environmental Precautions: Prevent from entering drains, waterways, or soil
Cleanup Methods: Use inert absorbent material, collect for disposal in suitable containers
This is where site diligence shows its value. All process flooring and containment zones are designed to channel spills to recovery tanks. We learned fast that quick cleanup limits product loss and risk of fire. The local team always works in pairs during cleanups to keep one eye on the work and another on safety.
Handling Practices: Only open containers in well-ventilated areas, avoid breathing vapors
Storage Requirements: Store in tightly closed original containers, away from ignition sources and incompatible chemicals like oxidizing agents
Temperature Sensitivity: Keep between 5°C and 35°C to avoid vapor pressure swings
Every barrel entering our warehouses gets logged in real time. We store everything with allowance for spill trays and strict zoning by hazard class. Regular deep cleaning and security checks ensure nothing sits unnoticed, and our tank farms use automated monitoring to flag temperature or pressure deviations before they spark trouble.
Engineering Controls: Local exhaust ventilation, gas detection alarms, process enclosure where feasible
Personal Protective Equipment: Chemical splash goggles, nitrile gloves, flame-resistant lab coats, approved respirators
Permissible Exposure Limit: Our plants monitor workplace concentrations and maintain values well below regulated levels
We emphasize maintenance. Exhaust ventilation and sensors come under strict schedules, not just post-incident reviews. No one enters a pump house during transfer without gear checks. Gloves and goggles hang in every doorway, and local supervisors inspect PPE for wear before every shift begins.
Boiling Point: 112–116°C
Flash Point: Approximately 25°C (closed cup)
Autoignition Temperature: 430°C
Vapor Pressure: Moderate, increases rapidly above room temperature
Solubility: Slightly soluble in water, easily mixes with most organics
It’s part of our daily controls to monitor temperature and pressure in every line, not just for quality assurance but to keep operations within the steady states that make physical properties less of a hazard. Sudden shifts are flagged in the control room, and by reinforcing a culture where operators speak up, small deviations never wait long for correction.
Chemical Stability: Stable under recommended storage conditions
Incompatible Materials: Strong acids, oxidizing agents, bases
Decomposition Products: Oxides of carbon under fire conditions
We run continuous risk reviews, often guided by lived experience. There is no shortcut around incompatibles: every transfer pipe and storage area is mapped and signed for what can safely move through it. Segregation is rigorously enforced, and we update controls any time process chemistry changes.
Acute Toxicity: Inhalation may affect the central nervous system, causing headache or drowsiness
Skin Contact: Prolonged or repeated exposure can lead to mild irritation
Long-Term Effects: Repeated over-exposure shows no evidence of chronic toxicity at controlled levels
Every health finding prompts us to review operating procedures and workplace hygiene. We keep detailed exposure logs, which show real-life exposures rarely come close to hazard thresholds, thanks to worker engagement and carefully managed air monitoring.
Aquatic Toxicity: Harmful to aquatic life with long-lasting effects
Persistence and Degradability: Readily biodegradable under aerobic conditions
Bioaccumulation: Low potential
Production lines include dedicated containment for liquid wastes. Discharge is never a question, the only policy is collection and certified offsite treatment. We work with local authorities to monitor groundwater and surface water in the plant vicinity, and data trends inform next season’s upgrades to our recovery systems.
Recommended Disposal: Incineration in licensed facilities, or transfer to authorized chemical waste handlers
Container Management: Do not reuse; triple rinse and treat as hazardous
We never cut corners on disposal, since improper handling bounces right back to haunt the manufacturer as well as the community. We audit our contractors, checking manifest records and, in several cases, running spot checks to confirm proper destruction of waste. Each campaign run produces clear waste accounting, right down to used rags and filter pads.
UN Number: UN1123
Proper Shipping Name: Butyl Acetates
Transport Hazard Class: 3 - Flammable Liquids
Packing Group: III
We don't let logistics become an afterthought. All shipping partners prove their drivers and equipment meet code. CFR training applies to everyone laying hands on a drum, both before and after it leaves our gate. Vehicles arrive sealed and inspected before unloading at the customer site. Documentation traces every step, so nothing goes missing in the system.
Global Inventories: Registered with major regulatory frameworks such as REACH, TSCA, AICS
Hazard Classifications: Complies with GHS and local chemical safety standards
We follow updates from regulatory bodies and communicate changes to our process managers the moment guidance arrives. Internal audits measure compliance performance, and findings direct extra training or systems upgrades so the standards remain enforceable on the ground, not just on paper.
