suitable platinum compounds for this purpose include chloroplatinic acid platinous chloride and various compounds containing the platinum amine complex the present molecular sieve when employed either as an adsorbent or as a catalyst should be dehydrated at least partially this can be done by heating to a temperature in the range of 200 u00b0 c to about 370 u00b0 c in an atmosphere such as air nitrogen etc and at atmospheric subatmospheric or superatmospheric pressures for between 30 minutes and 48 hours dehydration can also be performed at room temperature merely by placing the emm 23 in a vacuum but a longer time is required to obtain a sufficient amount of dehydration the present molecular sieve can be used as an adsorbent or particularly in its aluminosilicate form as a catalyst to catalyze a wide variety of organic compound conversion processes including many of present commercial industrial importance examples of chemical conversion processes which are effectively catalyzed by the crystalline material of this invention by itself or in combination with one or more other catalytically active substances including other crystalline catalysts include those requiring a catalyst with acid activity examples of organic conversion processes which may be catalyzed by emm 23 include cracking hydrocracking disproportionation alkylation oligomerization and isomerization as in the case of many catalysts it may be desirable to incorporate emm 23 with another material resistant to the temperatures and other conditions employed in organic conversion processes such materials include active and inactive materials and synthetic or naturally occurring zeolites as.
