Palladium is a silvery-white metal that belongs to the platinum group metals family. Because of its ductility and malleability, the metal can be folded very thinly. It is quite resistant to air corrosion and to acid action at ordinary temperatures. Palladium can absorb up to 900 times its own hydrogen volume. While absorbing, it expands like a sponge that swells up if it absorbs water.
Popular Uses of Palladium
The main use of palladium is in catalytic converters for automobiles. Palladium that is finely divided serve as a catalyst for petroleum cracking and hydrogenation/dehydrogenation reactions. Palladium is also used in jewelry such as in white gold. The dental, surgical instrument manufacturing, electrical contacts and watch making industries also benefit from palladium. The compound is also used in purifying hydrogen due to the easy diffusing of the gas when palladium is heated.
Palladium acetate is palladium’s chemical compound. It is commonly used as a precursor for palladium catalyst synthesis and a catalyst for organic reactions. Palladium acetate is a red-brown solid which crystallizes monoclinic plates. It has a trimetric structure that is composed of an equilateral triangle of Pd atoms. But palladium acetate that is prepared in a different way tends to be pale pink in color with a structure determined by diffracting X-ray powder to be composed of palladium atoms in infinite chains.
Preparing the Compound
In trimeric form, preparing palladium acetate can be done by refluxing palladium sponge using hot glacial nitric and acetic acid. An excessive amount of palladium sponge metal is used for preventing the contamination of a material with nitrite ligand. This nitro variant has various catalytic activity and solubility in a number of reactions. It is important to prevent and control the amount of such impurity to come up with quality palladium acetate. It is important to note that if warmed using alcohols or when boiled with other solvents on a long period of time, the compound will decompose to palladium. Palladium acetate is a catalyst for a lot of organic reactions by combining various organic compound classes like dienes, alkenes, vinyl halides and alkyl to come up with reactive adducts.
Those who need palladium acetate msds should find a reputable provider. Given the complexity of the substance and the role in plays in industries, the need to find a genuine compound cannot be overstated. Catalyst products are available online and picking the right company requires doing one’s homework.
