What is 1 methyl?
1-Methylimidazole is prepared mainly by two routes industrially. The main one is acid-catalysed methylation of imidazole by methanol. The compound can be synthesized on a laboratory scale by methylation of imidazole at the pyridine-like nitrogen and subsequent deprotonation.
What is the density of 1 methylimidazole?
1.03 g/cm³1-Methylimidazole / Density
What is NMP in chemistry?
N-Methyl-2-Pyrrolidone (NMP) is a high boiling, polar aprotic, low viscosity liquid. NMP has a good solvency for a wide range of organic and inorganic compounds and it is miscible with water at all temperatures and has a high chemical and thermal stability.
How do you remove imidazole from a reaction mixture?
If it is necessary to eliminate the imidazole, it can be removed by dialysis, ammonium sulfate precipitation, ultrafiltration or by using a size-exclusion desalting column.
What is imidazolium ionic liquid?
Imidazolium-based ionic liquids in nanomaterial synthesis. Generally, ILs have chemical attributes such as non-volatility, negligible vapor pressure and most importantly, high thermal stability [59]. Several ILS-incorporated methods and protocols have been reported for the fabrication of inorganic nanomaterials.
What does imidazole mean in chemistry?
Imidazole is an organic compound with the formula C3N2H4. It is a white or colourless solid that is soluble in water, producing a mildly alkaline solution. In chemistry, it is an aromatic heterocycle, classified as a diazole, and has non-adjacent nitrogen atoms.
Why is imidazole a base?
Explain why N1 of imidazole is most basic In the cyclic structure, there are 2 pi bonds (between C2-C3 and N1-C5) and one lone pair on N4 that can interact with each other to form a delocalised pi system. Therefore the lone pair will be available for donation, which makes N1 the strongest base in this question.
What is structure of pyrrolidine?
C4H9NPyrrolidine / Formula
What is the molecular weight of 1-methylimidazole?

What is the mechanism of acylation of 1-methylimidazole?
Acylation of 1-methylimidazole at C-2 takes place via the azolium salt which deprotonates to form an ylide, and then rearranges 〈84TL1715, 86CHE587〉. This reaction has similarities to the Regel acylation process (see CHEC-I).
What is the precursor of pyrrole-imidazole?
1-Methylimidazole is also the precursor for the synthesis of the methylimidazole monomer of pyrrole-imidazole polyamides. These polymers can selectively bind specific sequences of double-stranded DNA by intercalating in a sequence dependent manner.
