Tert-butyl propanoate

Tert-butyl propanoate is an organic chemical compound with the molecular formula C7H14O2 and CAS number 20487-40-5. It belongs to the ester family, formed by the reaction between propanoic acid and tert-butanol. With a molecular weight of 130.18 g/mol, this compound is classified as a flammable liquid (Flam. Liq. 2) under GHS regulations and requires careful handling due to its fire hazard properties.

Tert-butyl propanoate is typically a clear, colorless liquid at room temperature with a characteristic fruity ester odor. As an ester compound, it exhibits limited solubility in water but is generally soluble in organic solvents such as alcohols and hydrocarbons. The compound has a relatively low boiling point due to its ester structure and displays typical properties of aliphatic esters including moderate volatility.

Tert-butyl propanoate is primarily used as a solvent in various industrial applications, particularly in coatings, paints, and adhesives formulations. It serves as an intermediate in organic synthesis and chemical manufacturing processes. The compound is also utilized in the production of specialty chemicals and can function as a flavoring agent in certain applications due to its pleasant fruity odor characteristic of esters.

Tert-butyl propanoate must be handled with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods to prevent vapor accumulation. Eliminate all ignition sources as the compound is classified as Flam. Liq. 2. Avoid skin and eye contact, and ensure emergency washing facilities are readily available during handling operations.

Tert-butyl propanoate should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames. Storage areas must be equipped with appropriate fire suppression systems due to its flammable nature (Class 3 ADR). Keep containers away from incompatible materials such as strong oxidizing agents and store in areas with temperature control to prevent vapor buildup.

In case of skin contact with tert-butyl propanoate, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for 15 minutes while holding eyelids open. If inhaled, move the person to fresh air immediately. In case of ingestion, do not induce vomiting and seek medical attention promptly.

Tert-butyl propanoate waste must be disposed of according to local, national, and European waste regulations as a flammable liquid waste. The compound should be collected in appropriate containers and handed over to licensed waste disposal companies specializing in chemical waste treatment. Incineration at approved high-temperature facilities is typically the preferred disposal method. Never dispose of this substance down drains or in regular waste streams.

Tert-butyl propanoate is classified under ADR Class 3 (flammable liquids), Packing Group II, requiring specific transport packaging and labeling according to dangerous goods regulations. Packages must display the appropriate hazard labels and UN identification numbers. Transportation vehicles must comply with ADR requirements including proper ventilation, fire extinguishing equipment, and driver certification for dangerous goods transport. Special routing restrictions may apply in certain areas.

Tert-butyl propanoate is subject to European CLP regulation requiring classification as Flam. Liq. 2 with danger signal word and GHS02 pictogram. Under REACH regulation, it requires registration for manufacture or import above certain tonnages. The compound is not classified as a Substance of Very High Concern (SVHC). Standard industrial chemical regulations apply regarding workplace exposure limits, safety data sheet requirements, and professional use restrictions.
