摘要：
The use of magnesium oxide of specified, low, reactivity in a process for the production of overbased magnesium sulphonates, together with the introduction of water and an alcohol, into the reaction mixture during carbonation, makes it possible to prepare high base number products which have very low post carbonation sediments and which can be purified by rapid filtration.
