What is N Methylformamide used for?
N-Methylformamide (NMF) is a colorless, nearly odorless, organic compound and secondary amide with molecular formula CH3NHCHO, which is a liquid at room temperature. NMF is mainly used as a reagent in various organic syntheses with limited applications as a highly polar solvent.
How do you find boiling point at different pressures?
If the boiling point values for a specified substance at a specified BP temperature and pressure are given, one can determine the Boiling Point at different vapor pressure values using the Clausis-Clapeyron Equation. The Clausis-Clapeyron Equation is derived from VP2=VP1e−ΔHvRT at two different temperatures.
Does DMF evaporate at room temperature?
On my system, DMF will evaporate at ~ 50 deg C, so if your compound is stable at elevated temperature, you can give that a try, large scale or not.
Is NMP soluble in water?
N-Methyl-2-pyrrolidone (NMP) is an organic compound consisting of a 5-membered lactam….N-Methyl-2-pyrrolidone.
|Boiling point||202 to 204 °C (396 to 399 °F; 475 to 477 K)|
|Solubility in water||Soluble|
|Solubility in Ethanol, acetone, diethylether, ethyl acetate, chloroform, benzene||Soluble|
What is the rate constant of vapor phase reaction of N-methylformamide?
The rate constant for the vapor-phase reaction of N-methylformamide with photochemically-produced hydroxyl radicals has been estimated as 6.8X10-12 cu cm/molecule-sec at 25 °C (SRC) using a structure estimation method (1).
How to measure N-methylformamide concentration in urine?
THE SENSITIVITY OF THE METHOD CAN BE INCREASED TO MEASURE 0.5 UL/L OF N-METHYLFORMAMIDE BY CHROMATOGRAPHING DICHLOROMETHANE EXTRACTS OF CONCENTRATED URINE RESIDUES. Methylformamide concentrations in urine may be determined by flame-ionization gas chromatography, involving direct sample introduction.
What is the Henry’s Law constant for N-methylformamide?
The Henry’s Law constant for N-methylformamide is estimated as 2.0X10-8 atm-cu m/mole (SRC) based upon its vapor pressure, 0.253 mm Hg (1), and water solubility, 1.0X10+6 mg/l (2). This Henry’s Law constant indicates that N-methylformamide is expected to be essentially nonvolatile from water surfaces (3).
Does N-methylformamide biodegrade in the environment?
Therefore, N-methylformamide may biodegrade in the environment (SRC). The rate constant for the vapor-phase reaction of N-methylformamide with photochemically-produced hydroxyl radicals has been estimated as 6.8X10-12 cu cm/molecule-sec at 25 °C (SRC) using a structure estimation method (1).
