ABSTRACT:
The invention provides a process for the manufacture of a crystalline, phosphorus-containing zeolite of the ZSM-5 type by mixing water, a silicon dioxide source, an alkali metal hydroxide and an aluminum compound, and reacting this mixture at a temperature of from 95.degree. to 230.degree.
