Tetrahydro pyrrole Usage And Synthesis
PyrrolidinePyrrolidine 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 .

Standards for Use of Food AdditivesThe maximum amount of food additives permitted and maximum allowable residue limits
Chemical PropertiesIt 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℃.
UsesPharmaceutical raw materials, organic synthesis, special organic solvents.
It can be used for the preparation of drugs, fungicides, insecticides, etc.
CategoryFlammable liquid.
Toxicity gradingHighly toxic.
Acute toxicityOral-rat LD50: 300 mg/kg; Oral-Mouse LD50: 450 mg/kg.
Flammability hazard characteristicsWhen exposed to fire, high temperature, oxidant, it is flammable; when heat, toxic nitric oxide gas can produce.
Storage CharacteristicsTreasury ventilation low-temperature drying; oxidants, acids stored separately.
Extinguishing agentDry, dry sand, carbon dioxide, foam, 1211 fire extinguishing agent.
Occupational standardsSTEL 0.1 mg /m.
Chemical Propertiescolourless to pale yellow liquid with a penetrating
UsesA 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).
DefinitionChEBI: A cyclic amine whose five-membered ring contains four carbon atoms and one nitrogen atom; the parent compound of the pyrrolidine family.
General DescriptionA 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 ReactionsHighly flammable. Very soluble in water.
Reactivity ProfileTetrahydro 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.
Health HazardMay 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.
Fire HazardFlammable/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.
