Comments

N-methyl-2-pyrrolidone (NMP) is a chemical compound. It can be viewed as a lactam of N-methylaminobutyric acid and is thus a γ-lactam. - Recovery and preparation - N-methyl-2-pyrrolidone is produced on a large scale by reaction of γ-butyrolactone with methylamine at temperatures of 250-400 °C and pressures of 60-120 bar in adiabatically operated tubular reactors. The reaction proceeds exothermically. The product mixture is then depressurized and separated by distillation. The yield of N-methyl-2-pyrrolidone is usually more than 97%. - The starting material γ-butyrolactone is itself produced practically exclusively from 1,4-butanediol, which in turn can be produced by numerous processes from fossil or renewable raw materials. - Properties - Physical Properties - N-methyl-2-pyrrolidone is a light-sensitive, hygroscopic, colorless to yellowish liquid with a faint amine-like odor, which is miscible with water. The viscosity at 25 °C is 1.65 mPa-s, and the surface tension is 40.7 mN/m. Under normal pressure, the compound boils at 203 °C. According to Antoine, the vapor pressure function is given by log10(P) = A-(B/(T+C)) (P in kPa, T in K) with A = 7.4, B = 2570 and C = 0 in the temperature range from 361 K to 477 K. - The density of NMP decreases with increasing temperature. The temperature dependence function can be described by a quadratic equation according to ρ=α+β-T+γ-T2 with α = 1.26202, β = -7.0026-10-4 , γ = -2.8771-10-7 and T = temperature in Kelvin. - The specific heat capacity increases with temperature. - Compilation of main thermodynamic properties Critical temperature Tc = 721.7 K; Critical pressure pc = 45.2 bar ; Critical density ρc = 3.22 mol-l - Melting enthalpy ΔfH = 18.1 kJ-mol-1 at melting point; Vaporization enthalpy ΔVH = 49.5 kJ-mol-1 at normal pressure boiling point - NMP has a refractive index very close to that of commercial glass (1.4700). Consequently, glass rods and glass pipettes virtually disappear optically in this chemical. - Chemical properties - NMP is a very weak base. When treated with hydrogen chloride, a solid hydrochloride can be obtained which melts at 86-88 °C. The aqueous solution reacts alkaline. A 10% aqueous solution shows a pH of 7.7 to 8.0. The compound is chemically very stable. The lactam ring can be opened only by means of strong acids and bases, resulting in 4-N-methylaminobutyric acid. NMP has limited stability to oxygen, with oxidation starting at the 5-position and forming the N-methylsuccinimide via various intermediates. This product can be prepared selectively from NMP using ruthenium tetroxide as oxidant. With halogenating agents, such as phosgene or phosphorus pentachloride, the compound reacts to give the 2-chloro-1-methylpyrrolidinium chloride, which can be further reacted with various nucleophiles, such as amines or alkoxides. - NMP acts as a catalyst in the synthesis of carboxylic acid chlorides from the carboxylic acids.- With strong bases such as lithium diisopropylamide, NMP can be deprotonated in the 3-position, forming an amidenolate structure that can be reacted with alkyl halides or aryl bromides.- Safety Characteristics - NMP forms flammable vapor-air mixtures above the flash point of 86 °C. The explosion range is between 1.52 vol% (63 g/m3) as the lower explosion limit (LEL) and 9.5 vol% (392 g/m3) as the upper explosion limit (UEL). A correlation of the lower explosion limit with the vapor pressure function results in a lower explosion point of 79 °C. The limiting oxygen concentration is 8.1% by volume at 200 °C. The limiting gap width was determined to be 0.93 mm. This results in an assignment to explosion group IIA. The ignition temperature is 265 °C. The substance thus falls into temperature class T3. NMP decomposes at a temperature above 300 °C, producing carbon monoxide, carbon dioxide, nitrous gases and hydrogen cyanide. The conductivity is 2-10-6 S/m at 25 °C. - Uses - NMP is often used as a solvent because of its thermal stability and high polarity. It is suitable as a solvent for polymers such as acrylates, epoxies, polyurethanes, polyvinyl chloride, polyimides, polyamideimide and for numerous organic syntheses. Other important applications include paint removal and the production of polyurethane foam (PU foam). An important technical application is the extraction of 1,3-butadiene from C4 hydrocarbon streams. It is also used to absorb acidic components in gas scrubbing.
