1,3-Butadiene (/ ˌ b juː t ə ˈ d aɪ iː n / ⓘ) [8] is the organic compound with the formula CH 2 =CH-CH=CH 2. It is a colorless gas that is easily condensed to a liquid. It is important industrially as a precursor to synthetic rubber. [9] The molecule can be viewed as the union of two vinyl groups. It is the simplest conjugated diene.

1,3-butadiene, which is used extensively in the synthetic rubber industry, is a highly reactive, potentially explosive compound, presenting particular problems for the design and execution of inhalation toxicity studies.

butadiene, either of two aliphatic organic compounds that have the formula C 4 H 6. The term ordinarily signifies the more important of the two, 1,3-butadiene, which is the major constituent of many synthetic rubbers. It was first manufactured in Germany during World War I from acetylene.

1,3-butadiene is often referred to simply as butadiene. However, the general term butadiene includes both the common industrial chemical 1,3-butadiene and 1,2-butadiene, a contaminant in some industrial processes. Physical characteristics of 1,3-butadiene are shown below.

1,3-butadiene is produced through the processing of petroleum and is mainly used in the production of synthetic rubber, but is also found in smaller amounts in plastics and fuel.

2024年6月5日 · Learn about 1,3-butadiene, exposure to which can raise your risk of leukemia. 1,3-Butadiene is a gas used to produce synthetic rubber products, such as tires, resins, and plastics. Other sources of exposure include car exhaust; tobacco smoke; and polluted air and water near industrial facilities.

2025年1月31日 · EPA preliminarily determined that 1,3-butadiene presents an unreasonable risk of injury to human health for workers and the general population (including fenceline communities). Workers may be exposed to 1,3-butadiene when making products or otherwise using 1,3-butadiene in the workplace.

2024年4月24日 · Butadiene is primary used as a monomer or comonomer in synthetic rubber production. It contributes to styrene-butadiene rubber, polybutadiene rubber, acrylonitrile-butadiene rubber, and chloroprene rubber. Beyond rubber production, butadiene plays a crucial role in several plastics.

2024年3月4日 · NIOSH: Pocket Guide to Chemical Hazards - 1,3-Butadiene Literature References ACGIH: Documentation of the Threshold Limit Values (TLVs) and Biological Exposure Indices (BEIs) - 1,3-Butadiene. See annual publication for most recent information.

1,3-Butadiene is a colorless gas with a mild gasoline-like odor. 1,3-Butadiene is almost always found at low levels in urban air samples, but it breaks down quickly in the air. In sunny weather, half of 1,3-butadiene goes away from the air in about 2 hours.
