Jacobs–Dorr process

Chemical Engineering

A wet process used for making phosphoric acid by the reaction of phosphoric acid on phosphate rock. The rock is dissolved in phosphoric acid and calcium sulphate to form a slurry of calcium phosphate. This is then converted to phosphoric acid and calcium sulphate in the exothermic reaction:
$C a_{3} {(P O_{4})}_{2} + 3 H_{2} S O_{4} \to 3 C a S O_{4} + 2 H_{3} P O_{4}$

Fluorine in the rock is evolved and is required to be scrubbed from the vent gas. The process was developed in the nineteenth century and there have been a number of variations of which the Dorr–Oliver process is still used.
