Abstract (en)
[origin: EP0002644A1] 1. New basic complexes of magnesium characterized in that they are obtained by putting into suspension into methanol, a compound based on "active" magnesium oxide in a quantity not exceeding 10 % by weight of "active" magnesium oxide in relation to the methanol, and subjecting the said suspension to a carbonation operation by means of carbonic gas at a temperature lower than 50 degrees C until no more carbonic gas is absorbed.
