Question solution of methylamine 40% from methylamine hcl?

"like others had said in earlier posts, methylamine forms an aqueous solution.
Take methylamine hydrochloride salt then dissolve it in an appropriate amount of water, then cool the solution to around 5* C and you add enough (pre-cooled) dilute NaOH(aq) to create aqueous methylamine freebase in solution with NaCl.
The higher the methylamine concentration is in the water, the more likely it will form a gas and separate so cooling the temperature will help you prevent it from escaping. Methylamine salt and base are plenty soluble in water. The salt is actually hygroscopic."
found this on sciencemadness, hope it could help :b
