METHOD FOR PREPARING HIGHER TRIALKYL ALUMINUM Russian patent published in 2006 - IPC C07F5/06 

FIELD: chemistry of metalloorganic compounds, chemical technology.

SUBSTANCE: invention relates to the improved method for preparing higher organoaluminum compounds, namely, to trialkyl aluminum. Method is carried out by interaction of aluminum preliminary subjected for activation with triethyl aluminum, hydrogen and olefin or olefin hydrocarbons at increased temperature and pressure. Activation of aluminum is carried out by interaction of aluminum, triethyl aluminum and part of olefin or olefin hydrocarbon and kept at temperature 40-50°C followed by feeding hydrogen and by increasing temperature to 125-135°C, kept at this temperature for 0.5-2 h, the remained amount of olefin or olefin hydrocarbon is fed and kept the formed reaction mass at temperature 135-155°C for 5-10 h. method provides enhancing conversion of olefins in the process for synthesis of trialkyls aluminum that are used broadly in different branches of industry, in particular, in production of polyolefins, higher saturated alcohols and others.

EFFECT: improved preparing method.
