Albemarle Corporation products

Ethanox 4701 antioxidant is an ashless oxidation inhibitor for a variety of lubricant products, including industrial lubricating oils, transformer oils, transmission fluids, transformer fluids, slideway oils, quench oils, greases, and engine oils.

At high temperatures (600 - 1000 °C), calcium hydride is a very strong reducing agent capable of reducing many metal oxides to pure metals. It is often used as a very efficient drying agent for organic solvents and gases. Mostly inert in combination with organic substances at normal temperatures, and being a rather weak condensation agent, calcium hydride can be used for drying ketones, esters, amines, halogenated hydrocarbons, higher alcohols, and phenols. CaH2 can be used as a hydrogen source because it is a hydrogen storage easy to transport. Another field of application is the determination of the water content in diesel fuel or kerosene. CaH2 is also used to determine the water content in plastic granules.

TiH2 is applied in airbag igniter mixtures. TiH2 increases coercivity when used for the production of AlNiCo, FeNiCoAlCu, and Ticonal sintered magnets. It is also used in the production of Ti alloys and semi-finished sintered products, both as a deoxidizing agent and for the absorption of carbon in powder metallurgy. Other applications are soldering ceramics or glass to metals, and titanium hydrides representing a hydrogen source for foaming metals.

Lithium chloride is a very hygroscopic salt and used in fluxes, humidity control, and zeolites. It is a raw material required for the electrolysis of lithium metal.

Albemarle offers a convenient ready-to-use. Lithium-bromide solution 30 % in THF as well as, Lithium-chloride solution 3% in THF, both with a very low water content. These solutions might be used, e.g. for the preparation of copper catalysts for Kumada-coupling protocols.

Other than lithium or magnesium reagents, zinc organometallics easily transmetalate on palladium-based catalysts and therefore find a wide use in Negishi-type cross-coupling protocols. A convenient way to produce organo zinc species in-situ is by transmetalation. Starting from organo magnesium or lithium compounds, the respective zinc species is immediately formed upon the addition of a zinc salt such as zinc chloride or bromide.
