For over 50 years, Unipar has been a role model in the manufacture of the chemicals present in our daily basic activities. Some of the components that we produce, such as chlorine and caustic soda, are essential in the health, textile and food industries, among others.
The uses and applications of these products are extensive. They range from water and sewage treatment, cotton and linen bleaching, and paper and cellulose production, to household cleaning products manufacture.
Here you’ll find detailed information on each of these compounds with their main features, their manufacture process and, mainly, their many applications

Hypochlorite is produced by a reaction between gaseous Chlorine and a Caustic soda solution being cooled down.
EDC (Dichloroethane) is obtained through a reaction between liquid chlorine and ethylene (inserted through a tube) and it is purified by distillation.
Hydrochloric acid is produced by a controlled combustion reaction of Chlorine and hydrogen, followed by absorption in treated water.
Caustic soda is produced by electrolysis and reduced through the evaporation process.
Then, the Soda is cooled down and stored in tanks, before being shipped.
(3) La salmuera se trata para eliminar impurezas, se filtra (4) y pasa por un estricto control (5) para alimentar las CÉLULAS ELECTROLÍTICAS.
If there are salt (sodium chloride) and water in stock, you need to supply our transformers with electricity.
(11) El cloro en esta forma se almacena en tanques (12) donde se carga en camiones especiales
La ELECTRÓLISIS tiene lugar en la celda. Y así, la energía eléctrica actúa sobre la salmuera y la transforma en SODA CÁUSTICA, CLORO E HIDRÓGENO.
A Soda Cáustica é produzida na eletrólise e concentrada pelo processo de evaporação.
The ELECTROLYSIS takes place in the cell. This way, electric energy acts on the brine and transforms it into CAUSTIC SODA, CHLORINE AND HYDROGEN.
(3) A SALMOURA é tratada para eliminar impurezas, filtrada (4) e passa sob um rigoroso controle (5) para alimentar as CÉLULAS ELETROLÍTICAS.
Next, prepare the PICKLE obtained from dissolving the salt in the water to use afterwards in the ELECTROLYSIS.
