Examples of uses of this molecule in Industry and Healthcare
1-Butene is used as a co-monomer for the production of high density (HDPE) and linear low density (LLDPE) polyethylene products and for the manufacture of polybutylene. 1-Butene is also used as feedstock for the production of 1,2-butylene oxide, methylethylketone (MEK), maleic anhydride and n-butyl derivatives. Butene-1 has good solvent properties.

Recommendations : Air Liquide has gathered data on the compatibility of gases with materials to assist you in evaluating which materials to use for a gas system. Although the information has been compiled from what Air Liquide believes are reliable sources (International Standards: Compatibility of cylinder and valve materials with gas content; Part 1- Metallic materials: ISO11114-1 (March 2012), Part 2 - Non-metallic materials: ISO11114-2 (April 2013), it must be used with extreme caution and engineering judgement. No raw data such as these can cover all conditions of concentration, temperature, humidity, impurities and aeration. It is therefore recommended that this table is only used to identify possible materials for applications at high pressure and ambient temperature. Extensive investigation and testing under the specific conditions of use need to be carried out to validate a material selection for a given application.

General information
1-Butene, also known as butylene, is an alkene with the formula C4H8. It is a gas at room temperature and pressure, but can be liquefied by lowering the temperature or raising the pressure on it, in a manner similar to pressurised butane. This gas is colourless, highly flammable with no distinct odour. Although not naturally present in petroleum in high percentages, it can be produced from petrochemicals or by catalytic cracking of petroleum.
