Butanol from the fermentation process was first discovered Alcohol fusel oil obtained by the French C.-A. Wurtz in 1852. In 1913, the British Strange - Graham company first corn production by fermentation process acetone, butanol is used as the main byproduct. Later, due to the increased demand for n-butanol n-butanol manufacturers, fermentation plants modified to produce n-butanol-based, acetone, ethanol as a byproduct. During World War II, the German chemical company Ruhr butanol Oxo propylene production. 1950s, the rise of petroleum chemical n-butanol, n-butanol synthesis is developing rapidly, especially in the fastest propylene Oxo. 3 Industrial production method editor industrial system n-butanol fermentation mainly, propylene Oxo alcohol and acetaldehyde, formaldehyde condensation three. In addition, higher alcohols from ethylene system also byproducts n-butanol. Fermentation cereals (corn, corn cob, rye, wheat) starch, water mixed into the mash, the retort sterilization, adding pure acetone-butanol bacteria at 36 ~ 37 ° C butanol fermentation price quotes, fermented mash separated by distillation of n-butanol, acetone and ethanol. Molasses can also be used as raw material. Oxo propylene, carbon monoxide and hydrogen by cobalt or rhodium catalyst (see complex catalyst) Oxo reaction of n-butyraldehyde and isobutyraldehyde, the hydrogenation of n-butanol and isobutanol. Absorption band position of solvent effects on the absorption band of the impact with the solvent, solute and transition band categories. Depending on the nature of both the solute and solvent have different effects, if stronger than the ground state, the absorption of the relevant transition between the molecules of the excited state of the stabilizing effect with bathochromic. On the contrary, those who make more stable ground state, then to blue shift. When a non-polar solute molecules, interactions between non-polar solvent with only weak dispersion, the effect of solvent on the solute tend to be small, the spectrum of the solution is close to the gaseous state. If the solute excited state dipole, or accompanied by charge transfer, the absorption band wavelength with the dielectric constant or increasing the refractive index of the solvent and the redshift.
