Process for the separation and refining of amines

A process for the separation and refining of lower alkyl amines which comprises treating a mixture containing alkyl amines, alcohol and water with 15% to 40% sulfuric acid, whereby the amines are converted to amine sulfates with heat generation, employing the generated heat in 60 assisting in the vaporization of alcohol and water from the amine sulfates, liberating amines from the amine

History Developments and Applications | Titanium

This process allows the industry to extract and refine titanium at a commercially sustainable level, but it is still far from the effective process used for other metals Metals like iron can be refined with a continuous flow through a blast furnace, but titanium must be processed in batched The ore and sponge can be sealed in the reactors for days, and the total extraction and processing time can take weeks
