Talk:Methylamine

Headline text

I took a crack at filling in some of the chemical data for this. It would be useful for someone to proofread my work though, and there is a lot more to add.

A material safety data sheet is here and is probably useful for this.

Can anyone recommend open source software for drawing the structure? --Pmetzger 17:36, 22 September 2005 (UTC)

Recommended Software

I use Accelrys to model SMILES and molecules, then save the file as a .pdb and open it with Qutemol.

Really a solvent?

This compound is a gas at room temperature. I understand it is usually found as a solution. Is it really used as a solvent? How??? --Rifleman 82 02:14, 11 November 2007 (UTC)

Ammonia is sometimes used as a solvent, despite having an even lower boiling point, so that shouldn't be a problem. --Itub 13:00, 12 November 2007 (UTC)

I don't know how much it is actually used in practice, but research on its use as a solvent dates from 1906! LIQUID METHYLAMINE AS A SOLVENT, AND A STUDY OF ITS CHEMICAL REACTIVITY. H. D. Gibbs; J. Am. Chem. Soc.; 1906; 28(10); 1395-1422. --Itub 13:05, 12 November 2007 (UTC)

While I've heard of liquid ammonia and supercritical CO2 as solvents, I've never heard of liquid methylamine... See Ed's comments at User talk:Shaddack#Solvent over-enthusiasm?. --Rifleman 82 13:24, 12 November 2007 (UTC)

After further searching, I've only been able to find very few obscure mentions of it as a solvent. So perhaps it doesn't deserve being categorized as a solvent, or even being mentioned as a solvent unless some specific example is given with a reference. --Itub 13:53, 12 November 2007 (UTC)

Synthesis equation

In the synthesis of methylamine using ammonium hydrochloride, the last equation is wrong, because, the HCl formed is missing : The right equation is : CH₂NH₂-HCl + H₂CO + H₂O → CH₃NH₂ • HCl + HCOOH Source: [1] Kafein (talk) 08:38, 14 May 2008 (UTC)

pKa - incorrect value

According to D. H. Everett and B. R. W. Pinsent, Proc. Roy.SOC. (London), 215, 426 (1952) which is cited as a resource of information in Hall, H.K., J. Am. Chem. Soc., 1957, 79, 5441., the number that claimed to be pKa of methylamine is in fact pKa of methylammonium ion. I suggest removing that number. Unfortunately, I was not able to find the right value, but the old one is definitely wrong. 147.231.123.171 (talk) 12:14, 21 April 2011 (UTC)

IUPAC name

Can methylmaine be also called aminomethane under IUPAC naming?

In rule 811.3 of the Blue book, it mentions that if NH2 is the principal group, has to be given the name with the suffix amine, such that methanamine is okay, but aminomethane is not.
