Safety measures in the production of organoaluminum compounds

Taking into consideration a) the specific properties of organoaluminum compounds, especially lower aluminumtrialkyls, and their hydride-, halo-gene- and alkoxy derivatives, which are highly flammable in air and explode at contact with water b) the use of hydrogen, ethylene, isobutene, ethylene, isobutene, ethylchloride, sodium and aluminum (finely dispersed and active, which can self-inflame in air), the production of organoaluminum compounds can be considered one of the most dangerous chemical productions. Therefore, safety measures and fire prevention are especially important. 

When dealing with organoaluminum compounds, it is necessaiy  

Pipes for pure aluminumtrialkyls should be short and mounted so that the product flows freely and completely (no pockets tilted towards the storage container). Pipings for organoaluminum compounds should be located at a distance from those for other reactive substances, water and vapour. The production of organoaluminum compounds requires apparatuses without lower drains the product can be sent from one apparatus into another by nitrogen flow through immersed pipes. 

To prevent the inverse flow of the product, backflow gates should be used. Workshops for organoaluminum compounds should not be fitted with water and vapour piping. Heat carriers can be only inert hydrocarbons (pentane, mineral oil, etc.). Tanks and reactors should have drains. Dirt can be separated with highly productive hermeticised centrifuges. 

Apparatuses, piping and fittings for the production of organoaluminum compounds can be made from all major steel brands. Lead and aluminum
