New complexes basic of magnesium and their application for the manufacture of additives for lubricating oils, dispersants, detergents -

摘要

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.
