What is N-Butanol?

N-Butanol, likewise known as 1-butanol, butanol, is a kind of alcohol, each molecule has four carbon atoms, and its molecular formula is CH3CH2CH2CH2OH. There are three isomers, isobutanol, sec-butanol, as well as tert-butanol. It is a colorless, wine-scented fluid at space temperature level, with a boiling point of 117.7 ° C, a thickness (20 ° C )of 0.8109 g/cm3, a freezing point of -89.0 ° C, a flash point of 36 ~ 38 ° C, as well as an auto-ignition factor of 689F. The refractive index (n20D) is 1.3993. The solubility in water at 20 ° C is 7.7% (weight), the solubility of water in n-butanol is 20.1% (weight), as well as it is miscible with ethanol, ether and also other organic solvents. Vapor and air develop an eruptive blend with an explosion restriction of 3.7%~ 10.2% (quantity portion). n-Butanol is the raw product for the manufacturing of plasticizer dibutyl phthalate, and is additionally used as a solvent for the manufacture of butyl acrylate, butyl acetate and butyl glycol ether.

N-Butanol Uses

  1. N-Butanol is utilized as a reagent for chromatographic analysis and is additionally utilized in organic synthesis, etc.
  2. N-Butanol is a food flavor enabled by my nation’s “Sanitary Requirements for using Food Additives”, and also is primarily made use of to prepare edible tastes such as banana, lotion, whiskey as well as cheese. The dosage is 34mg/kg in candy; 32mg/kg in baked products; 12mg/kg in soft drinks; 7.0 mg/kg in chilly beverages; 4.0 mg/kg in cream; 1.0 mg/kg in alcohol.
  3. N-Butanol is an intermediate of the herbicides 2,4-D-butyl ester, butachlor, diflufenapyr (Banzaide) as well as fenflufenacil.
  4. N-Butanol is an edible spice that is enabled to be used in GB 2760-96. Generally made use of for the prep work of flavors such as banana, lotion, whiskey as well as cheese. Likewise made use of as extraction solvent as well as pigment diluent.
  5. N-Butanol is mainly made use of to make n-butyl ester plasticizers of phthalic acid, dibutyl phthalate, aliphatic dibasic acid and also phosphoric acid, which are commonly utilized in various plastic as well as rubber products. It is also the raw product for the production of butyraldehyde, butyric acid, butyl acetate, butylamine as well as butyl lactate in organic synthesis. It is likewise an extractant for the manufacturing of melamine material, acrylic acid, oil, medications (such as anti-biotics, hormonal agents and vitamins) as well as scents, ingredients for alkyd resin finishings, etc. It can also be utilized as a solvent for natural dyes as well as printing inks, as a dewaxing representative.
  6. n-Butanol is a primary aliphatic alcohol historically used as a solvent in nail care cosmetics, but new use concentration data suggest that it is also used at low concentrations in eye makeup, personal hygiene and shaving cosmetics.

Production Method of N-Butanol

The preparation methods of n-butanol are as follows.
In the past, butanol was obtained by hydrolysis and fermentation using potatoes, grains or sugars as raw materials. The product obtained from the fermentation broth contains about 54.8% to 58.5% of n-butanol, 30.9% to 33.7% of acetone, and 7.8% to 14.2% of ethanol. With the development of petrochemical industry, the fermentation method is gradually eliminated. The reaction equation is as follows: (C6H10O5)n[n(H2O)]→[strain]n-C6H12O6[fermentation]→CH3COCH3+C4H9OH+C2H5OH
The obtained fermentation broth is then fractionated to obtain acetone, ethanol and n-butanol respectively.

Acetaldehyde method
Using acetaldehyde as a raw material, add dilute alkali solution, the temperature is below 20 ° C to obtain 2-hydroxybutyraldehyde, when the reaction reaches 50%, it will be terminated, the alkali is neutralized with acid, the unreacted acetaldehyde is recovered, and 2-hydroxybutyraldehyde is extracted at the bottom of the tower. Hydroxybutyraldehyde is dehydrated at 105-137°C with acid catalysts such as sulfuric acid and acetic acid to form crotonaldehyde, and then hydrogenated with copper complex catalyst at 160-240°C to obtain crude n-butanol and butyraldehyde, which are rectified to obtain finished products. CH3CH=CHCHO+H2[catalyst]CH3CH2CH2CHO+CH3CH2CH2CH2OH propylene oxo synthesis
Use propylene, carbon monoxide and hydrogen to react on the catalytic bed, the catalyst is zeolite adsorption of cobalt salt or fatty acid cobalt, the reaction temperature is 130 ~ 160 ℃, the reaction pressure is 20 ~ 25MPa, the reaction generates n-butyraldehyde and isobutyraldehyde, after refining Distillation for separation, catalytic hydrogenation of n-butyraldehyde to obtain n-butanol. CH3CH2CH2CHO+H2→CH3CH2CH2CH2OH
It is also possible to use a low-pressure method to synthesize butanol from propylene, carbon monoxide and water in one step. The reaction temperature is 100-104 °C and the pressure is 1.5 MPa. The mixture of pentacarbonyl iron, n-butylpyrrolidine and water is used, but the single-pass conversion rate of propylene is relatively high. Low, only 8% to 10%. Reaction equation: CH3CH=CH2+3CO+2H2O→n-C4H9OH+2CO2

Production of Renewable N-butanol by Catalytic Route

Fluctuating petroleum rates and also international ecological worries such as worldwide warming as well as environment adjustment have actually led to an expanding need for the manufacturing of eco-friendly chemicals as choices to petrochemicals. Butanol is a non-polar alcohol that is utilized in a variety of customer items and also as an important industrial intermediate. As a result, the manufacturing of butanol from renewable energies, such as biomass and natural waste, has actually drawn in fantastic attention from researchers. While typical eco-friendly butanol is generated by means of a fermentative route (i.e. acetone-butanol-ethanol (ABE) fermentation of biomass-derived sugars), fermentative butanol manufacturing suffers from troubles such as reduced butanol returns as well as by-product development as well as various other drawbacks, such as acetone and also ethanol. To prevent downsides, it has actually just recently been proposed to generate renewable butanol by means of a non-fermentative catalytic path. This review aims to supply a review of three different arising as well as assuring catalytic paths from biomass/organic waste-derived chemicals to butanol. The very first path entails the conversion of ethanol to butanol over steel and oxide stimulants. Unpredictable fats can be feedstock chemicals for the manufacturing of butanol utilizing permeable materials and metal drivers. Furthermore, biomass-derived syngas can be transformed to butanol over alkali metal-promoted non-precious metal drivers. The possibility of catalytic sustainable butanol manufacturing is additionally talked about. This evaluation aims to provide an introduction of 3 various emerging as well as promising catalytic pathways from biomass/organic waste-derived chemicals to butanol. The very first route involves the conversion of ethanol to butanol over steel and also oxide drivers. Unstable fats can be feedstock chemicals for the production of butanol using permeable materials as well as metal catalysts. On top of that, biomass-derived syngas can be converted to butanol over alkali metal-promoted non-precious metal stimulants. The possibility of catalytic sustainable butanol production is also reviewed. This review aims to offer a review of three different arising and also guaranteeing catalytic pathways from biomass/organic waste-derived chemicals to butanol. The initial route involves the conversion of ethanol to butanol over steel as well as oxide stimulants. Unstable fats can be feedstock chemicals for the production of butanol making use of porous products and also metal drivers. On top of that, biomass-derived syngas can be transformed to butanol over alkali metal-promoted non-precious steel drivers. The possibility of catalytic sustainable butanol manufacturing is additionally discussed. Biomass-derived syngas can be transformed to butanol over alkali metal-promoted non-precious metal catalysts. The possibility of catalytic sustainable butanol production is likewise gone over. Biomass-derived syngas can be converted to butanol over alkali metal-promoted non-precious steel stimulants. The possibility of catalytic sustainable N-Butanol manufacturing is likewise gone over.
