Basic Info of 1-Bromobutane

What is 1-Bromobutane?

1-Bromobutane is a natural bromine substance with the chemical formula CH3 (CH2) 3Br. It is a colorless fluid, although the unclean example is light yellow. It is generally utilized as a resource of butyl in organic synthesis.

1-Bromobutane is inappropriate with solid bases and also oxidants.

Bromobutane, also known as 1-bromobutane, is an important fine chemical product, mainly used as an alkylating agent in organic synthesis; Intermediate; organophosphine compound tributylphosphine, phase transfer catalyst and surfactant tetra-n-butylammonium bromide. It is also used as a solvent, an extractant for rare elements, a raw material for the synthesis of pesticides, medicines, dyes, and spices, and as a refrigerant and solvent.

1-Bromobutane Uses

  • 1-Bromobutane is made use of as an alkylating representative and also in the prep work of organometallic substances, such as n-butyl lithium.
  • 1-Bromobutane reacts with magnesium to prepare Grignard reagent, which is made use of to form carbon bond.
  • 1-Bromobutane can be utilized as a derivative reagent of multiple practical teams (amino, carboxyl and phenolic hydroxyl) of amino acids to enhance the hydrophobicity and also alkalinity of amino acids. It can likewise be used as an internal criterion for the metrology of 1 – as well as 2-bromopropane in human urine by headspace gas chromatography.
  • 1-Bromobutane is an intermediate in between the fungicides dimethylphenol and pyrimethamine.
  • 1-Bromobutane is utilized as a rare component extraction representative, an alkylating representative and also a basic material for natural synthesis, and also can likewise be made use of as a raw material for medication, dyes and scents.

Application of 1-Bromobutane

Preparation of 1-Bromobutane

The existing synthesis technology of bromobutane mainly includes n-butanol and sodium bromide sulfuric acid method, n-butanol and hydrobromic acid sulfuric acid method, n-butanol and hydrobromic acid solid acid catalysis method, n-butanol and bromine sulfurization method. and so on.

Hydrobromic acid and n-butanol react in the presence of a catalyst to produce 1-bromobutane. Since hydrobromic acid is a by-product of mass production of aryl bromide flame retardants, it is economically reasonable and has been a research hotspot in recent years. Sulfuric acid as a catalyst will produce a large amount of dilute sulfuric acid in the production process, and the post-processing is relatively troublesome; the solid acid catalysis method is easily affected by the failure of the catalyst, resulting in unstable product yield, and the complex synthesis and regeneration process of the catalyst affects the promotion of this process.
