Abstract
A crystalline zeolite, designated ZSM-34, having the composition as synthesized and in anhydrous form, expressed as mole ratios of oxides as follows: PA1 (0.5-1.3)R.sub.2 O: (0-0.15)Na.sub.2 O: (0.10-0.50)K.sub.2 O: Al.sub.2 O.sub.3 : XSiO.sub.2 where R is the organic nitrogen-containing cation derived from choline [(CH.sub.3).sub.3 NCH.sub.2 CH.sub.2 OH] and X is 8 to 50, said zeolite having an X-ray diffraction pattern, identifying it as a member of the offretite-erionite family and the ability, after calcination at 1000.degree. F for at least a period of time to remove the organic cation, to sorb at least 9.5 weight percent of n-hexane at ambient temperature and a n-hexane pressure of 20mm. Organic compound conversion is carried out in the presence of a catalytically-active form of said zeolite.
