摘要：
The object of the invention is a synthetic crystalline zeolite of the beta type characterized by:a) the following approximate general formula:M.sub.2/n O, Al.sub.2 O.sub.3, xSiO.sub.2where M represents a proton and/or a metallic cationn is the valence of Mx is a number ranging from 5 to 800,b) an X-ray diffraction diagram represented in table I of the description, andc) a fluorine content ranging from about 0.005 to 2.0% by weight, said zeolite having been furthermore synthetized in a fluoride medium.
