| Pyrrolidine Usage And Synthesis |
| Pyrrolidine |
Pyrrolidine is also known as tetrahydro pyrrole, and it is colorless to pale yellow liquid with a pungent ammonia odor, smoke in air, and toxic. The relative density is 0.8618, the boiling point is 88~89℃, refractive index is 1.4402 (28℃). It is strong alkaline, miscible with water, soluble in alcohol, ether and chloroform. Pyrrole can synthesize pyrrolidine by catalytic hydrogenation, pyrrolidine present in tobacco and carrot leaves, and it is natural substances, the molecular structure of pyrrolidine is cyclic secondary amine, which is generally the same with the reaction of amine. Pyrrolidine is an important organic chemical raw material, it can be used for drug preparation, fungicides and insecticides. Preparation: 1. 1,4-butanediol as the raw material, dehydrate to tetrahydrofuran, and then reacte with ammonia, then pyrrolidine can be obtained. 2. Furan as raw material, react with ammonia in the catalyst at 400℃ can obtain tetrahydro pyrrole. 3. The 1,4-dichloro-butane as raw material, react with ammonia, pyrrolidine can be obtained. 4. Pyrrole as raw material, with the catalyst of rhodium or ruthenium, with the reaction of reduction can obtain . The above information is edited by the chemicalbook of Wang Xiaodong. |
| Chemical Properties | It is colorless, transparent liquid with special smell. When exposed to light or moist air, it can turn yellow. It can be soluble in water, ethanol. It is corrosive and flammable. Boiling point is 87.0~89.0℃. |
| Uses |
Pharmaceutical raw materials, organic synthesis, special organic solvents. It can be used for the preparation of drugs, fungicides, insecticides, etc. |
| Category | Flammable liquid. |
| Toxicity grading | Highly toxic. |
| Acute toxicity | Oral-rat LD50: 300 mg/kg; Oral-Mouse LD50: 450 mg/kg. |
| Flammability hazard characteristics | When exposed to fire, high temperature, oxidant, it is flammable; when heat, toxic nitric oxide gas can produce. |
| Storage Characteristics | Treasury ventilation low-temperature drying; oxidants, acids stored separately. |
| Extinguishing agent | Dry, dry sand, carbon dioxide, foam, 1211 fire extinguishing agent. |
| Occupational standards | STEL 0.1 mg /m. |
| Chemical Properties | colourless to pale yellow liquid with a penetrating |
| Chemical Properties | Pyrrolidine has a penetrating amine-type odor, reminiscent of ammonia and piperidine. It is nauseating and diffusive |
| Occurrence | Reported found in beer, bread, wheat bread, salmon caviar, fish, milk, leaves and stalks of celery, Camembert cheese, Limburger cheese, Russian cheeses, tilsit cheese, other cheeses, caviar, raw fatty fish, beer, Finnish whiskey, white wine, red wine, coffee, radish, malt, roasted peanut, sweet corn and roasted barley. |
| Uses | Uses of this compound in any major scalehave not been made. It occurs in tobacco andcarrot leaves. It is formed by reduction ofpyrrole. |
| Uses | A heterocyclic compound used as a building block in the synthesis of wide range of pharmaceutical compounds, namely matrix metalloprotein inhibitors (MMPIs) and aminopeptidase N inhibitors (APNIs). |
| Definition | ChEBI: A cyclic amine whose five-membered ring contains four carbon atoms and one nitrogen atom; the parent compound of the pyrrolidine family. |
| Definition | pyrrolidine: A saturated heterocycliccompound having one nitrogenatom in a five-membered ring,C4H9N; r.d. 0.87; m.p. –63°C b.p.87°C. It is found in certain plants andthe ring structure is present in manyalkaloids. |
| Preparation | Via overall 5-endo-trig cyclizations of homoallylic tosylamides. |
| Aroma threshold values | Detection: 20.2 ppm |
| Taste threshold values | Taste characteristics at 50 ppm: ammonia and fishy, amine-like with seaweed and shellfish nuances. |
| General Description | A colorless to pale yellow liquid with an ammonia-like odor. Flash point 37°F. Density 0.85 g / cm3. Vapors heavier than air. Produces toxic oxides of nitrogen during combustion. |
| Air & Water Reactions | Highly flammable. Very soluble in water. |
| Reactivity Profile | Tetrahydro pyrrole neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. May generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrides. An explosion occurred when a mixture of Tetrahydro pyrrole, benzaldehyde, and propionic acid was heated in an attempt to form porphyrins. |
| Hazard | Flammable, dangerous fire risk. Toxic by ingestion and inhalation. |
| Health Hazard | May cause toxic effects if inhaled or ingested/swallowed. Contact with substance may cause severe burns to skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution. |
| Health Hazard | The acute toxicity of pyrrolidine is moderateon test animals. It is somewhat less toxicthan pyrrole. The vapors are an irritant tothe eyes and respiratory tract. The liquid iscorrosive to the skin. Contact with the eyescan cause damage. The oral LD50 value inrats is 300 mg/kg, while the inhalation LC50value in mice is 1300 mg/m3/2 h (NIOSH1986). |
| Fire Hazard | Flammable/combustible material. May be ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. |
| Safety Profile | Poison by ingestion and intravenous routes. Moderately toxic by inhalation. Dangerous fire hazard when exposed to heat or flame; can react vigorously with oxidizing materials. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits hghly toxic fumes of NOx. |
| Enzyme inhibitor | This colorless liquid (FWfree-base = 71.122 g/mol; B.P. = 88.5-89°C), also known as tetrahydropyrrole, is the structural foundation of many biomolecules, including proline. Pyrrolidine has also been reported in tobacco and carrot leaves. Pyrrolidine is miscible in water and is a strong base (pKa = 11.27 at 25°C). Target(s): D-amino-acid oxidase, weakly inhibited; and prolyl-tRNA synthetase. |
| Purification Methods | Dry pyrrolidine with BaO or sodium, then fractionally distil it, under N2, through a Todd column (p 11) packed with glass helices. [Beilstein 20 H 159, 20 I 36, 20 II 79, 20 III/IV 2072, 20/1 V 162.] |
