The offering includes metal alkyl co-catalysts and catalyst support precursors, external stereomodifiers (donors), metallocenes and aluminoxane based metallocene activators. The most important target applications are:

 

Polyolefins

Aluminum, boron and zinc alkyl co-catalysts, as well as magnesium alkyl catalyst support precursors and alkyl silane stereomodifiers (donors) are all used in Ziegler-Natta type catalysts for the production of a vast variety of PE (LLDPE, HDP) and PP resin grades with all state-of-the-art gas phase, slurry and solution polymerization process technologies.
Metallocenes, aluminoxane based metallocene activators and aluminum alkyl based co-catalysts and scavengers are used in Single-site catalyst systems for the production of a variety of high performance PE, PP and other olefin (co-)polymer resin grades with superior properties.

 

Elastomers

Aluminum alkyl co-catalysts and aluminoxane activators are well established as key components used in Ziegler-Natta type and Single-site catalyst systems for production of certain polyolefin elastomers like NBR and EPDM.

 

Olefin Oligomers

Aluminum and magnesium alkyls are important co-catalysts for olefin oligomerization. Typical olefin oligomers produced are C4 – C20 alpha olefins.

 

 

PHARMA AND FINE CHEMICALS

Our products are used as reagents in the production of pharmaceuticals and other fine chemicals to conduct complex chemical reactions. They are generally used to make active ingredients or key building blocks for pharmaceuticals.

 

Metal Alkyls

In addition to their outstanding performance as catalyst components in polymerization and oligomerization reaction, LANXESS's metal alkyls are very effective alkylation and reducing agents in organic synthesis and can also be used in olefin metathesis and Friedel-Crafts reactions with aromatic substrates.

 

 

INNOVATIONS

LANXESS's Organometallics products (marketed under the trade name AXION®) are essential components in a wide variety of end-use applications. Among some of the most recent innovations, AXION technology is used in the newest generation of catalyst systems for olefin oligomerization and polymerization. The so-called Single Site Catalyst systems utilize AXION MAO as an activator, in combination with metallocenes, to achieve new levels of performance in engineered plastics.

SERVICE & LOGISTICS

​In the planning and design of industrial equipment for handling Organometallics the special properties of these products must be taken into consideration. LANXESS has gained a lot of experience over more than 60 years in handling Organometallics safely.


Our Technical Service is ready to give advice on all technical and safety aspects concerning the safe handling of Organometallics during industrial processing, transport, unloading, mixing or storage. Our engineers can be involved at the design stage to advise and help in preparing the basic engineering design. In this way the special requirements of the plant can be considered right from the start, thus ensuring safe operation later on. Our Technical Service offers to train your operating personnel in handling Organometallics, including training about how transport containers can be connected and disconnected safely, how to take samples and how to prevent and fight fires.

Safety is a prime requirement when handling Organometallics. LANXESS has developed a range of transport containers for industrial and research applications. This comprises containers for small quantities in the laboratory, for larger quantities on a pilot plant scale and for large scale industrial use. These allow a safe and easy transfer of the products.

CHEMICAL AND PHYSICAL PROPERTIES

In this section, we discuss the safety aspects of the chemical and physical properties of organometallics.

>> Chemical and Physical Properties

 

 

PERSONAL SAFETY

With accidents involving metal alkyls the danger of burns and clothes catching fire is particularly great, owing to the self-igniting properties of these products. For this reason all plant personnel handling metal alkyls must wear protective, fire-proof clothing.

Apart from providing good protection against fire, the protective clothing must allow sufficient freedom of movement for manual operations, and also be light and easy to shed in case of spillage on the clothing.

>> Personal Safety Description

 

FIRE PRECAUTIONS AND FIRE FIGHTING

Preventative fire precautions are particularly important in dealing with metal alkyls and their preparations. Plants in which metal alkyls are used should therefore be designed and controlled in such a way as to help prevent further spillage of alkyls or spreading of fire in the case of an accident (automatic partitioning or closing of valves from a safe position).

Metal alkyl stores and blending stations should be built at a safe distance from production plant. The width of protective strips of ground, which are specified according to the German "Verordnung brennbare Flüssigkeiten" for combustible liquids with the lowest flash point, are the minimum requirements for safety distances.

TRANSPORT CONTAINERS

To meet the various requirements of transporting metal alkyls a special transport container system has been developed. These containers are used in sizes from 1,6 litres to 22,390 litres filling volume by always representing 90% of their total capacity. Altogether 10 different types are available.

They are: 2, 3, 4, 5, 5.1, 6, 6.1, 7, 8 and 9.

TRANSPORT SYSTEMS

Special flat top rail cars are required for transporting Container 7. A maximum of three filled or four empty containers can be transported on one rail car. The container removed from the car with a crane and lifting tackle. Alternatively the container can also be emptied directly from the car if the transfer station is suitably designed.

TRANSPORT REGULATIONS

The regulations for transports of dangerous goods, both nationally and internationally, depend on the respective conveyance. Pyrophoric metal alkyls are specified under class 4.2: Spontaneously Combustible Materials. Non-pyrophoric metal alkyls and diluted solutions of metal alkyls such as AXION® CA 1310 or AXION® CA 1330 are, however, materials of class 4.3 "substances which, by interaction with water, are liable to become spontaneously flammable or to give off flammable gases in dangerous quantities." The transport of our metal alkyls is always carried out in steel containers. These are special, pressure resistant, steel containers that have been constructed, tested and approved according to the existing transport regulations.

SOLUTIONS

Metal alkyls can also be supplied as solution in any concentration required by the customer. The transport containers for the solutions are the same as those used for neat metal alkyls. In handling the solutions, the same safety precautions should be applied as for the handing of undiluted metal alkyls. In addition, special precautions may be necessary for the solvent.

Solvents

Saturated hydrocarbons like hexane and heptane, aromatic hydrocarbons like toluene or inert hydrocarbon mixtures like white oils are suitable as solvents.
