CHARACTERISTICS OF N-METHYL-2-PYRROLIDONE (NMP):
N-Methyl-2-pyrrolidone (NMP) is a polar aprotic solvent with a high boiling point, strong polarity, low viscosity, good solubility, non-corrosivity, low toxicity, strong biodegradability, low volatility, and excellent chemical and thermal stability.
N-Methyl-2-pyrrolidone (NMP) is mainly used in the petrochemical, plastics, pharmaceuticals, pesticides, dye, and lithium-ion battery industries.
For example, N-Methyl-2-pyrrolidone (NMP) is widely used in the extraction of aromatic hydrocarbon, purification of acetylene, olefins, and diolefins, as well as in solvent for polymers and polymerization, including polyamide, polyimide, polyphenylene sulfide, and other engineering plastics or aramid, fiber.
In addition, N-Methyl-2-pyrrolidone (NMP) is also used in the manufacture of insulation materials, pesticides, pigments, and electronic products.
SYNTHESIS METHOD OF N-METHYL-2-PYRROLIDONE (NMP):
Based on the raw materials used, several processes such as succinonitrile route, condensation of γ-butyrolactone and methylamine, 4-oxidized methyl butyrate method, and 1,4-succinic acid route for manufacture of N-Methyl-2-pyrrolidone (NMP) were developed.
However, the only process currently employed in the industry is the condensation from γ-butyrolactone and methylamine.
The process technologies are similar in all N-Methyl-2-pyrrolidone (NMP) producers, yet the main difference is the production method for γ-butyrolactone intermediate.
BASF developed a process that included dehydrogenating BDO to γ-butyrolactone and then condensing with methylamine to produce N-Methyl-2-pyrrolidone (NMP).
Mitsubishi Chemical Corporation of Japan developed a process that included hydrogenation of maleic anhydride to γ-butyrolactone and condensation with methylamine to yield N-Methyl-2-pyrrolidone (NMP).
Synthesis of N-Methyl-2-pyrrolidone (NMP) by the condensation of γ-butyrolactone and methylamine in the absence of a catalyst was developed by BASF in 1936.
γ-Butyrolactone and methylamine are reacted at a temperature of 240–285 °C and a pressure of 5.0–8.0 MPa for 2–3 h, and the resulting N-Methyl-2-pyrrolidone (NMP) is purified by fractional distillation to obtain a high-purity product. Its reaction equation is as follows:
The reaction is carried out in two steps.
The first step is the reaction of γ-butyrolactone with methylamine to form N-methyl-γ-hydroxybutanamide, which is a reversible reaction and can be carried out at lower temperatures and lower pressure.
The second step is dehydrating and cyclizing N-methyl-γ-hydroxybutanamide to N-Methyl-2-pyrrolidone (NMP) under higher temperatures and pressure.
The two-step reactions can be carried out batch-wise in an autoclave or continuously in a tubular reactor.
Since the boiling point of N-Methyl-2-pyrrolidone (NMP) (204 °C) is very close to that of the raw material γ-butyrolactone (206 °C), separating them by fractional distillation is difficult.
Therefore, a large excess of methylamine is applied in the reaction (molar ratio of methylamine to γ-butyrolactone from 1.5 to 1.8) for complete conversion of γ-butyrolactone, simplifying the product separation process.
Anhydrous methylamine can be used as the raw material, but adding some water to the reaction system can increase the selectivity of N-Methyl-2-pyrrolidone (NMP).
The reaction solution is subjected to fractional distillation in the amine removal tower, in which the unreacted methylamine is distilled from the top and recycled to the reactor.
The bottom product of the tower is introduced into the light fraction removal tower, and all the remaining water is distilled from the top of the tower.
The light fraction is collected from the sideline on the tower's upper section.
The bottom product of the light fraction removal tower is introduced into the heavy fraction removal tower.
The heavy fraction is removed from the bottom of the tower, and N-Methyl-2-pyrrolidone (NMP) of high purity is obtained from the top.
The yield of N-Methyl-2-pyrrolidone (NMP) is up to 99% based on γ-butyrolactone.
PURISOL PROCESS OF N-METHYL-2-PYRROLIDONE (NMP):
In the Purisol process, developed by Lurgi AG in the 1960s, a cold (ca. -15 °C) aqueous solution of N-Methyl-2-pyrrolidone (NMP) is used to remove hydrogen sulfide from sour gas and from hydrodesulfurization facilities.
N-Methyl-2-pyrrolidone (NMP) offers some advantages over the
Selexol process in that N-Methyl-2-pyrrolidone (NMP) is more selective for hydrogen sulfide.
Furthermore, N-Methyl-2-pyrrolidone (NMP) promotes the hydrolysis of some carbonyl sulfide, a common component of sour gas:
COS + H2O → CO2 + H2S
This hydrolysis step further enriches the hydrogen sulfide content of the off-gas when the N-Methyl-2-pyrrolidone (NMP) is stripped.
The sulfur-rich gas is well suited for a Claus unit, which affords solid elemental sulfur.
PREPARATION OF N-METHYL-2-PYRROLIDONE (NMP):
N-Methyl-2-pyrrolidone (NMP) is produced industrially by a typical ester-to-amide conversion, by treating gamma-butyrolactone with methylamine.
Alternative routes include the partial hydrogenation of N-methylsuccinimide and the reaction of acrylonitrile with methylamine followed by hydrolysis.
About 200,000 to 250,000 tons are produced annually.
