Lower aliphatic amines are derivatives of ammonia with one, two, or all three of the hydrogen atoms replaced by alkyl groups of five carbons or less. Amines with higher alkyl groups are known as fatty amines. Amines are toxic, colorless gases or liquids, highly flammable, and have strong odors. Lower mol wt amines are water soluble and are sold as aqueous solutions and in pure form. Amines react with water and acids to form alkylammonium compounds analogous to ammonia. The base strengths in water of the primary, secondary, and tertiary amines and ammonia are essentially the same. The lower aliphatic amines are widely used as intermediates in the manufacture of medicinal, agricultural, textile, rubber, and plastic chemicals. Some commercially important alkylamines are methylamine, dimethylamine, ethylamine, n ‐propylamine, isopropylamine, allylamine, n ‐butylamine, isobutylamine, sec ‐butylamine, ethyl‐ n ‐butylamine, n ‐amylamine. The formation of salts with acids is the most characteristic reaction of amines. Alkylamine are corrosive to copper, copper‐containing alloys (brass), aluminum, zinc, zinc alloy, and galvanized surfaces. Lower aliphatic amines can be prepared by a variety of methods, using many different types of raw materials. By far the largest commercial applications involve the reaction of alcohol with ammonia to form the corresponding amines. Other methods are employed depending on the particular amine desired, raw material availability, and plant economics. The U. S. Department of Transportation requires labeling of all shipments of amines commensurate with the associated hazards. Alkylamines are toxic. Both the liquids and vapors can cause severe irritation to mucous membranes, eyes, and skin. Protective butyl rubber gloves, aprons, chemical face shields, and self‐contained breathing apparatus should be used by all personnel handling alkylamines.

Lower aliphatic amines are derivatives of ammonia with one, two, or all three of the hydrogen atoms replaced by alkyl groups of five carbons or less. Amines are toxic, colorless gases or liquids, highly flammable or combustible, and have strong odors. Lower molecular weight amines are water‐soluble and are sold as aqueous solutions and in pure form. Amines react with water and acids to form alkyl ammonium compounds analogous to ammonia. The lower aliphatic amines are widely used as intermediates in the manufacture of medicinal, agricultural, textile, rubber, and plastic chemicals. Lower aliphatic amines can be prepared by a variety of methods using different types of raw materials. By far the largest commercial applications involve the reaction of alcohol with ammonia to form the corresponding amines. Because of the hazards and toxicity of alkylamines, protective clothing, and a suitable respirator should be used when handling alkylamines, and proper labeling of shipments is required.

Methylamines are derivatives of ammonia with one, two, or all three hydrogen atoms replaced by methyl groups. Amines with alkyl groups of 2‐6 carbons are known as aliphatic amines, and amines with still larger alkyl groups are known as fatty amines. Methylamines are soluble in various organic solvents. All have a strong fishy odor. Methylamines are toxic, colorless gases or compressed liquids. They are highly flammable. Methylamines can be prepared by a variety of methods. Commercial processes involve reaction of methanol with ammonia to form the corresponding mono‐, di‐, and tri‐methylamines. Methylamines are used as intermediates for the manufacture of solvents, agricultural chemicals, water treatment chemicals, pharmaceuticals, surfactants, rubber chemicals, and food/feed additives.

Methylamines are derivatives of ammonia with one, two, or all three of the hydrogen atoms replaced by methyl groups. Methylamines are harmful, colorless gases or compressed liquids, highly flammable, and have very strong fishy or ammonia‐like odors. They are water soluble and are sold as either aqueous solutions or in pure form. Due to their high reactivity, the range of possible applications for methylamines is vast. Products manufactured from methylamines include solvents, crop protection agents, pharmaceuticals, surfactants, rubber chemicals, ion‐exchange resins, explosives, animal feed, building blocks for the paper industry, and water treatment materials.
