N-butyraldehyde, is also known as Aldehyde butyrique (French), Aldeide
butirrica (Italian), Butal, Butaldehyde, Butalyde, Butanal, n -
Butanal (Czech), Butanaldehyde, Butyl aldehyde, n - Butyl aldehyde,
Butyral, Butyraldehyd (German), n - Butyraldehyde, Butyric aldehyde,
and NCI - C5629.
N-butyraldehyde is a clear, mobile, flammable, liquid with a pungent
odor.
It is miscible with all common solvents, e.g., alcohols, ketones,
aldehydes, ethers, glycols, and aromatic and aliphatic hydrocarbons,
but is only sparingly soluble in water. It is an extremely flammable
liquid and vapor. The vapor may cause a flash fire.
N-butyraldehyde may irritate the skin and burn the eyes. Upon
degradation,
peroxides are formed. Inhalation of vapors and mists may cause a
narcotic effect.
----------------------------------------------
******APPLICATIONS******
The primary use for n-butyraldehyde is as a chemical intermediate in
producing other chemical commodities such as 2-Ethylhexanol (2-EH) and
n-butanol. Other products requiring n-butyraldehyde include
trimethylolpropane (TMP), n-butyric acid, polyvinyl butyral (PVB), and
methyl amyl ketone. Smaller applications include intermediates for
producing pharmaceuticals, crop protection agents, pesticides,
synthetic resins, antioxidants, vulcanization accelerators, tanning
auxiliaries, perfumery synthetics, and flavors.
----------------------------------------------
N-butyraldehyde is available in bulk quantities only.
N-butyraldehyde is neither explosive nor spontaneously flammable in
air.
However, it is flammable.

The primary use for n-butyraldehyde is as a chemical intermediate in
producing other chemical commodities such as 2-Ethylhexanol (2-EH) and
n-butanol:
2-Ethylhexanol (2-EH) -
2-Ethylhexanol is a valuable intermediate product for the chemical
industry. It finds application in a variety of plasticizers and is
also used in the synthesis of specialty chemicals. This alcohol
contains one primary hydroxyl group, which is terminally located.
2-Ethyhexnol is used in the production of dioctyl phthalate, other
plasticizers, coatings, adhesives and specialty chemicals. In these
end use areas, it contributes significantly to many high performance
characteristics such as flexibility, good adhesion, lower emissions
and fuel performance improvement.
The most important fields of application for 2-Ethylhexanol are the
manufacture of :
1. PLASTICIZERS
2-Ethylhaxanol is a feedstock for the production of low volatility
esters. The most common is di-(2-ethylhexyl) phthalate (DOP). Other
esters for use in plasticizer application are formed in the reaction
with the following acids: adipic acid, para-hydroxybenzoic acid ,
sebacic acid, azelaic acid, trimellitic acid, stearic acid,
terephthalic acid and phosphoric acid.
Also 2-Ethylhexanol is used in the production of heavy metal salts
used as PVC stabilizers.
2. ADHESIVES
2-Ethylhexanol gives an excellent balance of adhesiveness and low
emission qualities to adhesives. It also improves adhesion to a
variety of substrates.
3. COATINGS
2-Ethylhexanol is used as a low-volatility ingredient in solvent
blends for the dye stuffs and coatings industry. It is used as a flow
and gloss improver in baking finishes, as well as an additive in
dispersing and wetting agents for pigment pastes.
4. OTHERS
2-Ethylhexanol derivatives are used as an additive for diesel fuel to
reduce emissions. They are also used as additives to improve the
performance of lube oils and mining chemicals.

n-butanol
n-Butanol is a clear, mobile, neutral liquid with a characteristic
odor. It is miscible with all common solvents,
e.g., alcohols, ketones, aldehydes, ethers, glycols, and aromatic and
aliphatic hydrocarbons, but is only sparingly soluble in water.
n-Butanol may irritate the skin, eyes and mucous membranes. Inhalation
of
vapors or mists may cause a narcotic effect. Harmful effects on the
liver and kidneys have been observed in experiments on animals.
******Applications*******
A large part of the n-Butanol produced is converted into derivatives
(primarily esters) for use as solvents in
the coatings industry. n-Butanol is an eminently suitable solvent for
acid-curable lacquers and baking finishes
derived from urea (Plastopal), melamine (Luwipal), or phenolic resins.
Some butyl esters of dicarboxylic ac-
ids, phthalic anhydride, and acrylic acid are established plasticizers
for plastics, rubber mixes, and dispersions. The most important are
dibutylphthalate (DBP), benzylbutyl phthalate (BBP), and butyl
acrylate. Dibutyl sebacate (DBS) and dibutyl azelate (DBZ) are of
subordinate importance. The corresponding adipate is too volatile to
be a plasticizer and is therefore of no practical significance in
these applications.
The applications in which normal
butane can be used are as follows:
* solvent for dyes, e.g. in printing inks
* extractant in the production of drugs and natural substances such as
antibiotics, hormones, vitamins, alkaloids and camphor
* additive in polishes and cleaners, e.g. floor cleaners and stain
removers
* solubilizer in the textile industry, e.g. additive in spinning baths
or carrier for coloring plastics
* additive in deicing fluids
* gasoline additive (antiicing)
* mobile phase in paper and thin-layer chromatography
* humectant for cellulose nitrate
* feedstock for the production of glycol ethers (in reactions with
ethylene or propylene oxide)
* starting material for various butylmonocarboxylates, e.g. butyl
acetate and butyl butyrate, that are widely used as solvents.
* feedstock for the production of flotation aids, e.g. butyl xanthate
