The sodium form of the zeolite is converted to the acid form by placing it in a 100 mL beaker and stirring with a 1.0 M (NH4)2SO4 solution (10 mL/g zeolite) for 10 to 15 minutes at ambient temperature. The present invention meets such need by providing a process to make xylene that uses as the starting material the product resulting from the dimerization of isobutylene, which is an economical, versatile process that can accept isobutylene from a variety of sources. Accordingly, the examples should not be construed as limiting the scope of the embodiments herein. Stir until everything has dissolved. The phase purity and crystalline properties of Sr ion exchanged X zeolite was determined by the X-ray diffractometer instrument with Cu Kα Source (λ=1.542 A°). DIB as referred to herein, includes all forms of trimethylpentenes and dimethylhexenes. Step 2. The present disclosure relates to a process for the preparation of isomers of xylene. 7). The dimerization process is generally performed at a temperature in the range of about 5° C. to about 300° C. After completion of the dimerization of isobutylene, the dimerized product is removed from the dimerization reactor. The mixture of xylene is a bit greasy and has a sweet smell, which is generally encountered as a solvent. The process as claimed in claim 1, wherein. Oxygen is substantially absent from the reaction system when hydrogen is generated on an essentially quantitative basis as a removable by-product of the reaction rather than forming water. In this process Ba—X zeolite catalyst composite is replaced with commercially available Na—X zeolite catalyst. Example 12: Preparation of the Alkylation Catalyst Composite (Sr—X Zeolite Catalyst Composite) Using Na—X Zeolites. The immediate saving in money can be calculated from local costs for isopropanol versus ethanol and for xylene and its disposal. The more recent method is to use an elaborate multi-valve absorption process using molecular sieves. Compare with the expected peaks at 11.1 (s), 10.0 (s), 3.85 (vs) and 3.71(s) Å. dehydrogenation of n-hexane to benzene, Preparation of hydrocarbons from hydrocarbons containing a smaller number of carbon atoms, Preparation of hydrocarbons from hydrocarbons containing a smaller number of carbon atoms by addition between unsaturated hydrocarbons, Preparation of hydrocarbons from hydrocarbons containing a smaller number of carbon atoms by addition between unsaturated hydrocarbons by oligomerisation of well-defined unsaturated hydrocarbons without ring formation, Preparation of hydrocarbons from hydrocarbons containing a smaller number of carbon atoms by addition between unsaturated hydrocarbons by oligomerisation of well-defined unsaturated hydrocarbons without ring formation of alkenes, i.e. 16, 2000. 3. Individual preferences of the participating pathologists could be seen from the cross-tabulations, with a tendency for some to veer toward a generally favorable or critical score and the rest clustering toward the “normal.” Stratifying and cross-tabulating, as above, for tissue type (breast, skin, intestine) and consecutive sample number (1 to 10 for each tissue), in the same manner as above, again singled out xylene-free van Gieson sections, particularly for collagen-rich breast and skin, as accounting for most of the downgrading. It also occurs naturally in crude oil, gasoline, aircraft fuels. In this process Ba—X zeolite catalyst composite is replaced with Sr—X zeolites catalyst composite wherein the amount of catalyst was 2 g. The results so obtained are shown herein table 5 below. Blitz from the synthesis by L. D. Rollman and E. W. Valyocsik, “Zeolite Molecular Sieves,” Inorganic Syntheses, 22, 61-68 (1983) and the catalytic reaction by S. Whittingham. Percent alkylation of toluene using the alkylation catalyst, 1. The first solution is the source of alumina, sodium ions, and hydroxide ions; in the presence of excess base the alumina will form soluble Al(OH)4- ions. Manufacture of aromatic hydrocarbons from acyclic alkanes or acyclic alkenes is known in the art. Example 10: Preparation of the Alkylation Catalyst Composite (Sr—X Zeolite Catalyst Composite) Using Na—X Zeolites. A xylene-free method has been developed that excludes xylene, not only as the intermediate step before the paraffin baths, but also for deparaffinizing of the cut sections, which also eliminates the need for rehydration and dehydration for the staining and mounting steps. C represents XRD for the Sr—X zeolite catalyst composite obtained after repeating the method step of refluxing Na X-zeolite with strontium nitrate three times. 2 C 6 H 4 (CH 3) 2 ⇌ C 6 H 3 (CH 3) 3 + C 6 H 5 CH 3 C 6 H 4 (CH 3) 2 + CH 3 OH → C 6 H 3 (CH 3) 3 + H 2 O. Trimerization of acetone via aldol condensation, which is catalyzed and dehydrated by sulfuric acid affords a mixture of 1,3,5- and 1,2,4-trimethylbenzenes. The catalyst is 1.53% K/13.0% Cr/eta-alumina prepared as described in Example 1. The ratio of aqueous solution of sodium nitrate to zeolite was maintained as 10:1. Xylene exists in three different isomeric forms. For example, the catalyst can be formed by adding together suitable reagents such as salts of the required metal(s) and ammonium hydroxide or ammonium carbonate, and a salt of aluminum such as aluminum chloride or aluminum nitrate to form aluminum hydroxide. The process involves feeding to a catalytic dehydrogenation zone various hydrocarbon feeds that include isooctane, diisobutylene, and a mixture of isobutane and isobutylene. No. Lab Med 27: 638. The catalysts used in such process are, for example, those containing chromium or platinum. Step II—Preparation of an Alkylation Catalyst Composite (Ba—X Zeolite Catalyst Composite) Using Na—X Zeolite: The Na—X zeolite was treated with 0.5 M of barium acetate solution using the method described in step I to obtain a Ba—X zeolite. The isomers of xylene were prepared by employing the procedure described in the Example 1. ABANDONED -- FAILURE TO RESPOND TO AN OFFICE ACTION. Step 4. FIG. The pH should be in the 11-12 range as measured by pH paper. The isomers of xylene were prepared by employing the procedure described in the Example 1. While certain embodiments of the inventions have been described, these embodiments have been presented by way of example only, and are not intended to limit the scope of the inventions. The dimerization reactor can be any convenient reactor for this purpose, examples of which include reactors such as slurry phase, trickle bed, gas phase, catalytic distillation and the like.
