화학적 성질

Pyrrolidine appears as a colorless to pale yellow liquid with an ammonia-like odor. It is infinitely miscible with water and conventional organic solvents such as methanol, acetone, ether, and chloroform. It acts as a lachrymator. Chemically, pyrrolidine behaves like a secondary amine in every respect. For example, it undergoes Leuckart –Wallach and Mannich reactions and is readily converted into an enamine. In the presence of a catalyst, such as platinum at 360°C or rhodium at 650°C, pyrrole is formed. In the presence of a copper catalyst, N-methylpyrrolidone is converted into N-methylpyrrolidine.

상호 작용Formation of n-nitrosopyrrolidine in a dog's stomach from Na nitrate & pyrrolidine. N-nitrosopyrrolidine disappeared rapidly from stomach, probably due to absorption.
환경 거동TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 42(SRC), determined from a log Kow of 0.46(2) and a regression-derived equation(3), indicates that pyrrolidine is expected to have very high mobility in soil(SRC). The pKa of pyrrolidine is 11.31(4), indicating that this compound will primarily exist in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5). Volatilization of pyrrolidine from moist soil surfaces is not expected to be an important fate process as cations do not volatilize(SRC). Pyrrolidine is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 62.7 mm Hg(6). Pyrrolidine was found to degrade anaerobically via denitrification in 7-15 days in microbial consortia from freshwater sediments, estuarine sediments and activated sludge(7).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 42(SRC), determined from a log Kow of 0.46(2) and a regression-derived equation(3), indicates that pyrrolidine is not expected to adsorb to suspended solids and sediment(SRC). A pKa of 11.31(4) indicates pyrrolidine will exist almost entirely in the cation form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(5). According to a classification scheme(6), an estimated BCF of 3(SRC), from its log Kow(2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Pyrrolidine was found to degrade anaerobically via denitrification in 7-15 days in microbial consortia from freshwater sediments, estuarine sediments and activated sludge(8).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), pyrrolidine, which has a vapor pressure of 62.7 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase pyrrolidine is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC)the half-life for this reaction in air is estimated to be 5 hours(SRC), calculated from its rate constant of 7.8X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Pyrrolidine does not contain chromophores that absorb at wavelengths >290 nm(4) and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).

Soil Adsorption/MobilityThe Koc of pyrrolidine is estimated as 42(SRC), using a log Kow of 0.46(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that pyrrolidine is expected to have very high mobility in soil.

용도

Pyrrolidine is a flammable alkaline liquid that undergoes reactions typical of secondary amines. It is used to prepare pesticides and rubber accelerators and as a chemical intermediate (usually the hydrochloride form) in the pharmaceutical industry. There is relatively limited industrial exposure to this material.

일반 설명

Pyrrolidine is a saturated heterocycliccompound having one nitrogenatom in a five-membered ring. It is a colorless to pale yellow liquid with an ammonia-like odor. It is found in certain plants andthe ring structure is present in manyalkaloids. Flash point 37°F. Density 0.85 g / cm3. Vapors heavier than air. Produces toxic oxides of nitrogen during combustion.

제조 및 합성 방법

제조 방법

Pyrrolidine is formed by reduction of pyrrole. Via overall 5-endo-trig cyclizations of homoallylic tosylamides. Pyrrolidine can be produced from butanediol and ammonia, e.g., over an aluminum thorium oxide catalyst at 300°C or over a nickel catalyst at 200°C and 20 MPa under hydrogenation conditions. It can also be produced from THF and ammonia over aluminum oxide at 275-375°C.
