1-Butanol Usage And Synthesis
Characteristics and history of discovery 1-Butanol is a type of alcohol with four carbon atoms being contained per molecule. Its molecular formula is CH3CH2CH2CH2OH with three isomers, namely iso-butanol, sec-butanol and tert-butanol. It is colorless liquid with alcohol odor. 
It has the boiling point of being 117.7 ℃, the density (20 ℃) being ??0.8109g / cm3, the freezing point being -89.0 ℃, flash point being 36 ~ 38 ℃, self-ignition point being 689F and the refractive index being (n20D) 1.3993. At 20 ℃, its solubility in water is 7.7% (by weight) while the water solubility in 1-butanol was 20.1% (by weight). It is miscible with ethanol, ether and other kinds of organic solvents. It can be used as the solvents of a variety of paints and the raw material for producing the plasticizers, dibutyl phthalate. It can also be used for the manufacture of butyl acrylate, butyl acetate, and ethylene glycol butyl ether and also used as the extract of intermediates of organic synthesis and biochemical drugs and can also used in the manufacture of surfactants. Its steam can form explosive mixtures with air with the explosion limit being 3.7% ~ 10.2% (volume fraction). 
1-butanol was first discovered by C-A. Wurtz (French) from the fusel oil obtained from the fermentation process of alcohol in 1852. In 1913, the British Strange - Graham Companies have used corn as raw material for production of acetone through the fermentation process with butanol being the main byproduct. Later, due to the increasing demand for butanol, the fermentation production factory began to mainly synthesize n-butanol with acetone and ethanol being the major byproduct. During the Second World War, the German chemical company (Ruhr) began to apply propylene carboxyl method for the production of 1-butanol. With the rise of the oil industry in 1950s, the 1-butanol synthesis method had gotten rapid development with the propylene carboxyl method having the fastest speed.
Preparation of water saturated 1-butanol solution Add 21 mL of water and 100 mL of 1-butanol to separating funnel of 150 mL, shake for 3 min, stand for layering; and then remove the lower layer with the upper layer being water-saturated 1-butanol solution. (The density of water: 1 g / ml; 1-butanol density: 0.808 ~ 0.811 g / ml).
Content Analysis For the determination of 1-butanol and volatile impurities according to the general gas chromatography (GT-10), use the following conditions: 
Column steel column, length: 1.8m; inner diameter: 6.4mm, the packing material should be 10% polyethylene glycol 400M (PEG 400M) with the carrier being 60/80 mesh diatomaceous soil carrier.
Carrier gas: Helium with a flow rate of 45ml / min. Detector: Flame ionization type.
Injector temperature 150 ℃, column temperature 90 0 ℃ detector 150 ℃.

Chemical Properties It is colorless liquid with alcohol odor. At 20 ℃, its solubility in water is 7.7% (by weight) while the water solubility in 1-butanol was 20.1% (by weight). It is miscible with ethanol, ether and other kinds of organic solvents.
Uses It can be used as chromatography analysis reagents and also applied to organic synthesis, etc. 
Butanol is the allowable food flavors documented in the "food additives health standards" of China. It is mainly used for the preparation of food flavors of bananas, butter, cheese and whiskey. For the candy, the usage amount should be 34mg / kg; for baked foods, it should be 32mg / kg; for soft drinks, it should be 12mg / kg; for cold drinks, it should be 7.0mg / kg; for the cream, it should be 4.0mg / kg; for alcohol, it should be 1.0mg / kg. 
Butanol can be used as the intermediates of herbicide 2,4-D butyl ester, butachlor, fluazifop and fluazifop P butyl. 
GB 2760-96 provides it be the food flavor allowed by using it. It can be mainly used for the preparation of bananas, butter, cheese, whiskey and other flavor. It can also be used as extraction-purpose solvent and pigment diluent.
It is mainly used for the manufacture of the n-butyl plasticizers of phthalic acid, aliphatic dicarboxylic acid and phosphoric acid that are widely applied to various kinds of plastic and rubber products. It can also be used as the raw material of producing butyraldehyde, butyric acid, butyl-amine and butyl lactate in the field of organic synthesis. It can also be used as the extraction agent of oil, drugs (such as antibiotics, hormones and vitamins) and spices as well as the alkyd paint additives. It can be used as the solvent of organic dyes and printing ink and de-waxing agent.
It can be used for the production of the plasticizers of butyl acetate, dibutyl phthalate and phosphate and can also be used in the production of melamine resin, crylic acid, and epoxy varnish, etc.
Production method There are several methods for their preparation. 
Fermentation
In the past, the production of butanol has also used potatoes, grain or sugar as raw material and through their hydrolysis fermentation. The resulting product from the fermentation broth contains a butanol content of 54.8% ~ 58.5%, acetone content of 30.9% ~ 33.7%, and the ethanol content of 7.8% -14.2%. With the development of petrochemical industry, fermentation method has been gradually phased out. The reaction equation is as follows: (C6H10O5) n [n (H2O)] → [strain] n-C6H12O6 [fermentation] → CH3COCH3 + C4H9OH + C2H5OH
The resulted fermentation broth was further fractionated to obtain acetone, ethanol and n-butanol separately. 
Acetaldehyde method
Take acetaldehyde as raw material, add dilute alkali solution to give 2- hydroxybutyraldehyde at temperature below 20 ℃ with the reaction being stopped upon reaching 50%. Use alkali to neutralize the acid and recycle the unreacted acetaldehyde and extract the 2- hydroxybutyraldehyde. Then use acidic catalyst such as sulfuric acid and acetic acid for dehydration to obtain crotonaldehyde at 105 ~ 137 ℃, then use copper complex catalyst for hydrogenation at 160 ~ 240 ℃ to obtain the crude butyraldehyde and 1-butanol with distillation to obtain the products. CH3CH = CHCHO + H2 [catalyst] CH3CH2CH2CHO + CH3CH2CH2CH2OH
Its synthesis method including the following several ways:
Fermentation and Propylene carbonyl synthesis 
Put propylene, carbon monoxide and hydrogen to the catalytic bed for reaction with catalyst being zeolite for absorbing cobalt salt or fatty acid cobalt with the reaction temperature being 130 ~ 160 ℃ and the reaction pressure being 20 ~ 25MPa. The reaction can generate n-butyraldehyde and iso-butyraldehyde with separation via distillation and further catalytic hydrogenation of the n-butyraldehyde to obtain the 1-butanol. CH3CH2CH2CHO + H2 → CH3CH2CH2CH2OH
You can alternatively use low pressure method with first-step method of propylene, carbon monoxide and water for synthesizing the butanol with the reaction temperature being 100 ~ 104 ℃ and pressure being 1.5MPa. It applies the mixture of iron pentacarbonyl, n-butyl pyrrolidine and water. However, the one-way conversion of the propylene is low with only 8% to 10%. Reaction equation: CH3CH = CH2 + 3CO + 2H2O → n-C4H9OH + 2CO2
