Isobutanol is a short-chain alcohol that has been considered as a biodegradable fuel. This compound can be used as an alternative fuel to gasoline and other fossil fuels. Here are some of the features and benefits of isobutanol in the production of biodegradable fuels:

  • Renewable resource: Isobutanol can be produced from biological sources such as starch, sugar, and other organic materials, making it a sustainable option.
  • Emission reduction: Using isobutanol as a fuel can lead to reduced greenhouse gas emissions and air pollutants.
  • High performance: Isobutanol has better combustion properties than other alcohols such as ethanol, which can improve engine performance.
  • Solubility and miscibility: Isobutanol mixes well with gasoline and other fuels, allowing for blended use.
  • Stability: This compound is stable at various temperatures. It can be easily stored and transported under various conditions.

These properties make isobutanol a suitable option for the production of biodegradable fuels. And it can help reduce dependence on fossil fuels.

How is isobutanol made?

Today, isobutanol is produced from fossil fuels.

Isobutanol is obtained from the carbonylation of propylene. This method is carried out industrially by two methods.

Hydroformylation is the most common method of producing this chemical. In this method, a mixture of isobutyraldehydes is obtained.

CH3CH = CH2 + CO + H2 ——> CH3CH2CH2CHO

The above reaction is catalyzed by cobalt or rhodium accumulation. The resulting aldehydes are hydrogen-bonded to the alcohols and then separated. In carbonylation, the same products are obtained. But hydrogenation occurs by a water-gas exchange reaction.
