Hey you all,
I've been meaning to ask 2 things. First, as I understand about methylamine, a great excess of it is added to Br substitutions since it catches some of the forming HBr... (1 kg of 2b4m is 4.4 mol and 2 L of 40% methylamine contains 25.8 moles). So, since the methylamine is usually aqueous, my question is whether we could just use half of the methylamine and dissolve some quantity of NaOH with it (25.8/2=12.9 mol => 500 g NaOH)? If yes, then can we do it with every solvent, or will it react with some? Would ethyl acetate be ok?
My second question is about ethyl acetate in water - I once mixed small amounts of 2b4m, ethyl acetate and 40% methylamine, and after some stirring, it became a homogenous mixture. I heated it then, but the second time I didn't heat it, it remained biphasic. I wanted to ask you if this homogeneity can be achieved every time and if yes, then what are the conditions? Is it heat, or strong stirring, ratio to water?
