DESCRIPTION AND APPLICATIONS
There are three isopropanolamines called mono, di and tri-propanolamine with formula with formula CH3CH(OH)CH2NH2, CH3CH(OH)CH2]2NH, and CH3CH(OH)CH2]3N respectively. Monoisopropanolamine is a liquid at room temperature, while diisopropanolamine and triisopropanolamine are white solids. Isopropanolamine is a clear to yellow, corrossive, combustible liquid with a faint ammonia odor; boils at 159.9 C. It is soluble in water and very soluble in benzene and ether. Diisopropanolamine is a clear to yellow hygroscopic crystalline lumps; boils at 241 C, decomposes on heating producing toxic nitrogen oxides. It is a medium strong base and reacts violently with strong oxidants. It turns yellow when exposed to light and air. Diisopropanolamine and triisopropanolamine are commercially available in liquid grades contain deionized water typically 15%. These liquid grades should not be stored in the presence of aluminum due to the possibility of excessive corrosion and potential chemical reaction releasing flammable hydrogen gas at above 60 C. Isopropanolamines are used as an absorbent of acid gases in the refinery of natural gas and purification of ammonia. They are used as an emulsifying agent soluble in water and low alkalinity. They are used as a crosslinking catalyst in the production of polyurethanes. They are used as a component of insecticide, surfactants, rubber chemicals, corrosion inhibitors and pigment dispersants.

  • Gas-scrubber
    • Natural and refinery gas operations
    • Hydrogen sulfide (H2S) and CO2 gas removal

GENERAL DESCRIPTION OF AMINO ALCOHOL
Amino alcohols which have the physical and chemical characteristics of both alcohols and amines in one molecule . The amino alcohols are highly useful materials for a wide variety of applications.

•Chemcial intermediate application

    The amino alcohols are useful intermediates for a wide variety of synthesis. Many chemical reactions are common to the amino alcohols to form following examples;

    • amides and amide esters with carboxylic acids and organic acid esters
    • amino acids by oxidation of the alcohol and by hydrolysis of the amide
    • diamines with nitro alcohols
    • heterocyclic organic compounds such as oxazoline by dehydration
    • oxazolidine with aldehydes or ketones
    • oxazoline esters and diesters with three moles of an organic acid
    • poly(amideester) with dibasic acid
    • salts with inorganic acids

•Emulsifier applications

    Amino alcohols are used for production of efficient anionic emulsifiers and nonionic polyethylene emulsions. They appear in personal care products formulations and show better base strength, lower neutral equivalent, and lower volatility than traditional amine emulsifiers. Amino alcohols are used in personal-care products with the neutralization function of acid raw materials. They render resinous materials water-soluble. They provide base strength values with low odor levels, good water and alcohol solubility and color stability in cosmetics.

•Coating application

    The difunctionality of amino alcohols makes them useful as raw materials in polymer applications in both water- and solvent-based to increase the solubility of other components and improve solution stability. They function as a pigment dispersion-aid dispersant to enhance the wetting and viscosity stability. The salts of the amino alcohols are also used in coating to improve the package stability.

•Corrosion Inhibition application

    Amino Alcohols maintain a constant alkalinity in the boiling water flows and condensate not to form solid products which would impede line flow. This function is applied for corrosion Inhibits. They are widely employed in the preparation of  water soluble cationic flocculants and ion exchange resins which adsorb solid and colloidal particles by electrostatic attraction. They are used for water treatment, metal treatmet and absorption of CO2 gas.

•Catalyst application

    The salts of the amino alcohols like not only hydrochloride salts but also nitrate, sulfate, phosphate, and sulfonate salts can be used alone or in combination with other catalysts for balanced curing action with selected textile-resins.

•Biochemical application

    In biological field, amino alcohol structure is widely found in many drugs especially antihistamines. Shingosine, the major base of the sphingolipids in mammals for signal transmission and cell recognition is an amino alcohol.  Amino alcohol compounds are the starting materials in the preparation of beta-lactam antibiotics, humectant for foods and cosmetics, flavouring agents as well as many oral, injectable or topical pharmaceuticals. Amino alcohols are amine buffers used in a variety of medications.
