Understanding Butylene
Applications and Supply Types
What is Butylene?
Butylene, also known as butene, is a versatile hydrocarbon belonging to the alkene family. It plays a crucial role in various industrial applications due to its reactive double bond, making it an essential building block in the production of numerous chemicals and materials. In this blog post, we’ll explore what butylene is, its key applications, and the different supply types available in the market.
Butylene (C4H8) is an unsaturated hydrocarbon with four carbon atoms and a single double bond. It exists in four isomeric forms:
1. 1-Butene: A straight-chain isomer with the double bond between the first and second carbon atoms.
2. 2-Butene (cis and trans): A straight-chain isomer where the double bond is between the second and third carbon atoms. The cis and trans forms refer to the arrangement of hydrogen atoms around the double bond.
3. Isobutene (2-methylpropene): A branched isomer where the double bond is at the end of the chain.
Each isomer has unique properties and is used for different industrial purposes.

Key Applications of Butylene
Butylene is an important raw material in the petrochemical industry, with its applications spanning across various sectors:
1. Production of Polyethylene and Polypropylene: Butylene is a vital comonomer in the production of polyethylene and polypropylene, which are used to manufacture a wide range of plastic products, including packaging materials, containers, and automotive components.
2. Butyl Rubber: 1-Butene is used in the production of butyl rubber, a synthetic rubber known for its excellent impermeability to gases. Butyl rubber is widely used in the manufacture of inner tubes, tires, and other automotive products.
3. Fuel Additives: Butylene is used in the production of alkylate, a high-octane component of gasoline. Alkylate improves the quality of gasoline by reducing engine knocking and lowering emissions.
4. Chemical Intermediates: Butylene is a key intermediate in the production of various chemicals, including butylene oxide, butanol, and maleic anhydride. These chemicals are further used in the production of resins, solvents, and plasticizers.
5. Detergents and Surfactants: Isobutylene is used to produce surfactants and detergents, which are essential components in household cleaning products and personal care items.
6. Agricultural Chemicals: Butylene derivatives are used in the synthesis of herbicides and pesticides, contributing to the agricultural sector’s productivity.
Supply Types of Butylene
Butylene is available in different supply types depending on the specific industrial requirements:
1. Gaseous Form: Butylene is commonly supplied as a gas, stored in high-pressure cylinders or bulk storage tanks. The gaseous form is typically used in large-scale industrial processes where continuous supply is required.
2. Liquid Form: Butylene can also be supplied in a liquefied form under pressure or at low temperatures. This form is easier to transport and store, especially for smaller-scale operations.
3. Pipeline Supply: In areas with extensive petrochemical infrastructure, butylene is often supplied via pipelines directly to industrial facilities. This method ensures a continuous and reliable supply, essential for large-scale operations.
4. Bulk Delivery: For facilities without pipeline access, bulk delivery of butylene in specialized tankers is a common supply method. This ensures the efficient transport of large volumes of butylene to the required site.
5. Cylinder Supply: Smaller quantities of butylene can be supplied in gas cylinders, which are ideal for laboratories, research facilities, and smaller industrial applications.
Butylene is a versatile hydrocarbon with a wide range of industrial applications, from plastics production to fuel additives and chemical intermediates. Its availability in different supply types ensures that industries can access this crucial raw material according to their specific needs. Understanding the properties and uses of butylene is essential for optimizing its application in various sectors, ultimately contributing to the advancement of modern industrial processes.
