发明名称 VERFAHREN ZUR HERSTELLUNG BORHALTIGER MULTIMETALLSILIKATE MIT PENTASILSTRUKTUR
摘要 The invention relates to a process for the preparation of synthetic, crystalline, metal-containing borosilicates having a zeolite structure. According to the invention, this is effected by subjecting a reaction mixture which contains compounds of silicon, boron, sodium, aluminium and at least one subgroup element of the 4th period of the Periodic Table of elements, in particular chromium, nickel, cobalt, iron, gallium, zinc or manganese, in addition to hydroxide ions and water but no organic compounds or nitrogen compounds to a crystallisation process by maintaining a molar ratio of B/(B + Al) of 0.1 to 1.0 and a molar ratio M/(B + Al) of 0.05 to 5 for a period of 1 to 100 hours, preferably 5 to 20 hours under hydrothermal conditions at 403 K to 593 K. M denotes the subgroup element of the 4th period of the Periodic Table of elements.
