Claims
- 1. Catalyst consisting essentially of an active charcoal support in the form of particles having a specific surface area between about 600 m.sup.2 /g and 1300 m.sup.2 /g, wherein said particles are in the form of cylinders having a diameter from 0.3 to 1.5 mm and a length of 0.3 to 5 mm, or spheres having a diameter from 0.3 to 2 mm, the said particles being loaded with a precious metal from group VIII of the Periodic Table of Elements.
- 2. Catalyst according to claim 1, wherein the precious metal is palladium.
- 3. Catalyst according to claim 1, wherein the diameter of the particles is from 0.7 to 1.2 mm.
- 4. Catalyst for use in the dehalogenation of alphahalogenated carboxylic acids consisting essentially of an active charcoal support in the form of particles having a specific surface area between about 600 m.sup.2 /g and 1300 m.sup.2 /g, wherein said particles are in the form of cylinders having a diameter from 0.3 to 1.5 mm and a length of 0.3 to 5 mm, or spheres having a diameter from 0.3 to 2 mm, the said particles being loaded with a precious metal from groups VIII of the Periodic Table of Elements.
- 5. Catalyst for use in the purification of monochloroacetic acid consisting essentially of an active charcoal support in the form of particles having a specific surface area between about 600 m.sup.2 /g and 1300 m.sup.2 /g, wherein said particles are in the form of cylinders having a diameter from 0.3 to 1.5 mm and a length of 0.3 to 5 mm, or spheres having a diameter from 0.3 to 2 mm, the said particles being loaded with a precious metal from groups VIII of the Periodic Table of Elements.
