POLYCHLOROALUMINATES OF ALKALI-EARTH METALS

摘要

FIELD: chemistry. ^ SUBSTANCE: invention can be used in chemical industry. Polychloroaluminates of alkali-earth metals are obtained by reacting chlorides of alkali-earth metals with aluminium chloride in diethyl ether medium and have general chemical formula MCl24AlCl3nEt2O, where when M = Ca n = 4.5; when M = Sr n = 1, 1.5; when M = Ba n = 2.5. ^ EFFECT: said chemical compounds are suitable for use as reagents in purifying oil products and natural gas from mercaptans and hydrogen sulphide, catalysts used in chloromethylation and alkylation of aromatic hydrocarbons and starting materials during production of metal hydrides. ^ 6 tbl
