Description | Isopropylamine (propan-2-amine, IUPAC) is a colorless, volatile liquid. It is highly flammable, with a flammable range of 2%–10.4% in air. Boiling point is 93°F (33°C), flash point is ?15°F (?26°C), and ignition temperature is 756°F (402°C). It is miscible with water, with a specific gravity of 0.69, which is lighter than water. Vapor density is 2.04, which is heavier than air. In addition to flammability, isopropylamine is a strong irritant to tissue and has a TLV of 5 ppm in air. The four-digit UN identification number is 1221. The NFPA 704 designation for isopropylamine is health 3, flammability 4, and reactivity 0. Primary uses for isopropylamine are pharmaceuticals, dyes, insecticides, and as a dehairing agent. |
Chemical Properties | Isopropylamine is a colorless, flammable liquid. Isopropylamine is miscible with water, alcohol, and ether.The odor threshold reportedly ranges from 0.21 to 0.70 ppm; the pungent, ammoniacal odor becomes irritating at 24mg/m3 (110). |
Physical properties | Colorless liquid with a penetrating, ammonia-like odor. Experimentally determined detection and recognition odor threshold concentrations were 500 μg/m3 (210 ppbv) and 1.7 mg/m3 (700 ppbv), respectively (Hellman and Small, 1974). An odor threshold concentration of 25 ppbv was reported by Nagata and Takeuchi (1990). |
Occurrence | Not reported found in natu |
Uses | Isopropylamine is used as a dehairing agentand as an intermediate in the preparation ofmany organics. |
Uses | Isopropylamine is an organic compound is a widely used for the synthesis of pharmaceutical and agricultural goods such as glyphosphate herbicides and as an additive for petroleum industry. |
Uses | Solvent, intermediate in synthesis of rubber accelerators, pharmaceuticals, dyes, insecticides, bactericides, textile specialties, and surface-active agents, dehairing agent, solubilizer for 2,4-D acid. |
Production Methods | Isopropylamine can be produced from the corresponding alcohol by reacting with ammonia in the presence of a dehydrating catalyst, or from the chloride by reacting with ammonia under pressure. It is also reported that this amine can be produced from acetone and ammonia or from the acetone oxime (HSDB 1989). |
Definition | ChEBI: A member of the class of alkylamines that is propane carrying an amino group at position 2. |
Aroma threshold values | High strength odor; fishy type; recommend smelling in a 0.10% solution or less. |
General Description | A clear colorless liquid with an ammonia-like odor. Flash point -35°F. Boiling point 90°F. Less dense than water Vapors heavier than air. Produces toxic oxides of nitrogen during combustion. Used as a solvent and to make other chemicals. |
Air & Water Reactions | Highly flammable. Water soluble. |
Reactivity Profile | Isopropylamine is a colorless, alkaline liquid, very volatile, moderately toxic, highly flammable. Dangerous fire hazard when exposed to heat, flame, sparks, or strong oxidizers. When heated to decomposition Isopropylamine emits toxic fumes of oxides of nitrogen [M. K.]. A mixture of Isopropylamine and perchloryl fluoride resulted in an uncontrolled oxidation and/or explosion, [J. Org. Chem., 1980, 45, 4036]. The reaction of 1-chloro-2,3-epoxypropane and the amine and most probably other nitrogen bases, yields a violent exotherm, [Chem. & Ind., 1971, 994]. |
Hazard | Highly flammable, dangerous fire risk. Strong irritant to tissue. |
Health Hazard | Isopropylamine is a strong irritant to theeyes, skin, and respiratory system. A shortexposure to 10–20 ppm can cause irritationof the nose and throat in humans (Procturand Hughes 1978). Prolonged exposure tohigh concentrations may lead to pulmonaryedema. Skin contact can cause dermatitisand skin burns. Exposure to 8000 ppm for4 hours was lethal to rats. LD50 value, oral (mice): 2200 mg/kg. |
