Abstract
The application pertains to processes for producing alkali hydroxides or alkali sulfites using large molecular weight acid intermediates. Generally, a component comprising an alkaline-earth cation—small molecular weight acid anion may be reacted with a component comprising an alkali sulfate to form a component comprising an alkali cation—small molecular weight acid anion and a component comprising an alkaline-earth sulfate. A series of additional steps results in forming a component comprising an alkali hydroxide, or an alkali carbonate, or an alkali bicarbonate, or any combination thereof.

A process comprising:
- reacting a component comprising an alkaline-earth cation—weak acid anion with a component comprising a small molecular weight acid to form a component comprising an alkaline-earth cation—small molecular weight acid anion and a component comprising a weak acid derivative;
- reacting the component comprising an alkaline-earth cation—small molecular weight acid anion with a component comprising an alkali sulfate to form a component comprising an alkali cation—small molecular weight acid anion and a component comprising an alkaline-earth sulfate;
- reacting the component comprising an alkali cation—small molecular weight acid anion with a component comprising a large molecular weight acid anion;
