Reactions of ethylaluminum chlorides with Sodium Sulfate

Add time:07/31/2019    Source:sciencedirect.com

Reactions of diethylaluminum chloride, ethylaluminum dichloride and ethylaluminum sesquichloride with sodium sulfate were carried out. Diethylaluminum chloride exchanges quantitatively chlorine for sulfate with sodium sulfate,and forms a n-heptane-soluble organometallic compound having the empirical formula (C2H5)4Al2SO4 and a molecular weight of about 2300 in benzene. Two kinds of reaction are observed between ethylaluminum dichloride and sodium sulfate: formation of a complex which is insoluble in n-heptane and the dismutation reaction to diethylaluminum chloride. Reactions of ethylaluminum sesquichloride with sodium sulfate can be explained in forms of separate reactions of sodium sulfate with diethylaluminum chloride, and ethylaluminum dichloride.
