Crystallization is also a chemical solidâliquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs.In chemical engineering crystallization occurs in a crystallizer.or crystallization (see also recrystallization) to occur from a solution it must be supersaturated. This means that the solution has to contain more solute entities (molecules or ions) dissolved than it would contain under the equilibrium (saturated solution).

Methylamine is an organic compound with a formula of CH 3 NH 2. This colorless gas is a derivative of ammonia, but with one H atom replaced by a methyl group.It is the simplest primary amine. It is sold as a solution in methanol, ethanol, THF, and water, or as the anhydrous gas in pressurized metal containers.Industrially, methylamine is transported in its anhydrous form in pressurized railcars and tank trailers.ethylamine is prepared commercially by the reaction of ammonia with methanol in the presence of a silicoaluminate catalyst. Dimethylamine and trimethylamine are coproduced; the reaction kinetics and reactant ratios determine the ratio of the three products.
