Butyl Aldehyde: A Versatile Intermediate for Chemical Synthesis and Manufacturing
Butyl aldehyde, also known as butanal, is a valuable industrial chemical that serves as an essential building block in the production of a variety of everyday materials. As a low molecular weight aldehyde, it exhibits reactivity that makes it ideal for organic synthesis, resin manufacturing, and plasticizers production.
At United Chem, we supply high-purity butyl aldehyde to support industrial and research needs with a focus on quality, consistency, and safety. In this blog, we’ll explore what butyl aldehyde is, its main uses, safety considerations, and why sourcing from a reliable supplier is critical to operational success.
What Is Butyl Aldehyde?
Butyl aldehyde (C₄H₈O) is a colorless, flammable liquid with a pungent, sharp odor. Chemically, it belongs to the aldehyde family, characterized by the presence of the –CHO functional group. Its structure includes a straight-chain four-carbon backbone, making it one of the simplest aliphatic aldehydes.
Alternate names:
- Butanal
- 1-Butanal
- n-Butyl aldehyde
Key Properties of Butyl Aldehyde
- Molecular Formula: C₄H₈O
- Molar Mass: 72.11 g/mol
- Boiling Point: ~75°C
- Solubility: Slightly soluble in water, highly soluble in organic solvents
- Appearance: Clear, colorless liquid
- Odor: Strong, irritating odor typical of lower aldehydes
Butyl aldehyde is highly reactive and prone to oxidation, polymerization, and condensation reactions, making it a versatile compound in chemical manufacturing.
Industrial and Commercial Applications
Butyl aldehyde is primarily used as an intermediate in the synthesis of more complex chemicals. Its primary applications include:
1. Plasticizers Production
One of its largest end uses is in the production of 2-ethylhexanol, which is then used to make plasticizers such as DEHP (di(2-ethylhexyl) phthalate). These plasticizers are essential for softening PVC and other plastics.
2. Solvents and Resins
Butyl aldehyde is used in the manufacture of resins, coatings, and solvents. It contributes to the production of alkyd resins used in paints, varnishes, and printing inks.
3. Flavor and Fragrance Precursors
In controlled, food-grade forms, butanal may also be used as a flavoring agent or as a fragrance precursor in perfumery, though only under strict regulations due to its reactivity.
4. Chemical Synthesis
Butyl aldehyde is a useful starting material for the synthesis of alcohols, acids, and amines. It is widely used in laboratory research and pilot-scale chemical development.
Safety and Handling Guidelines
Due to its volatility and flammability, butyl aldehyde must be handled with care:
- Ventilation: Always work in a fume hood or well-ventilated area.
- Protective Equipment: Use chemical-resistant gloves, goggles, and lab coats.
- Storage: Store in tightly sealed containers away from heat, sparks, and oxidizing agents.
- Spill Response: In case of spills, use non-sparking tools and absorbents to contain and clean the area.
At United Chem, we include a Safety Data Sheet (SDS) with every order and are available to consult on safe handling practices.
