Procedure: The [W]s—H catalyst (55.7 mg; 4.96% W/SiO2; 15.01 micromol of W) supported on silica is prepared as described above and then the reactor is charged with propane at atmospheric pressure (propane/W=790) and heated at 150° C. under batch conditions. A mixture of methane, of ethane, of isobutane, of butane, of pentane and, in a smaller proportion, of isopentane and of hexane is gradually obtained according to the following Table 5. is prepared

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: After having closed the vessel, the mixture was polymerized with agitation for 6.5 hours at 363 K and for 3 hours at 393 K. After a conversion of about 40 to 47% of styrene was achieved, 1.275 g of potassium peroxodisulfate in 100 ml of water and 298 g of tricalcium phosphate in 3 liters of water were added. After 4 hours at 363 K, 5.9 kg of an expanding agent mixture consisting of 75% by weight of n-pentane and 25% by weight of isopentane was forced into the vessel within 15 to 20 minutes. After having closed the vessel the mixture was polymerized with agitation for 6.5 hours at 363 K and for 3 hours at 393 K was forced into the vessel within 15 to 20 minutes

Procedure: 20 ml of saturated α-cyclodextrin solution were mixed with 1 ml of isopentane and ultrasounded for 3 minutes in the ultrasonic bath. The resulting difficultly soluble complex was obtained through filtration and dried via calcium chloride. The resulting difficultly soluble complex was obtained through filtration dried via calcium chloride

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 100 ml of saturated β-cyclodextrin solution (1.8%) were cooled to 10° C. and mixed with 3 ml of isopentane. The resulting difficultly soluble complex was precipitated with constant stirring in the ultrasonic bath. The deposit was obtained in crystalline form through freeze-drying and filtering. The resulting difficultly soluble complex was precipitated The deposit was obtained in crystalline form through freeze-drying filtering

Procedure: Referring then to the drawing, there is shown an isostripper column 3. The isostripper column is typically operated at fractionation conditions including a bottom temperature of from about 350° to about 390° F., a top temperature of from about 125° to about 150° F., a bottom pressure of from about 155 to about 165 psig., and a top pressure of from about 145 to about 155 psig. In the present example, an alkylation reaction zone effluent stream, at a temperature of about 100° F., is charged to a heat exchanger 2 contained in line 1 whereby said stream is heated to a temperature of about 150° F. by indirect heat exchange with the hot alkylate product stream recovered from the isostripper column by way of line 27. The alkylation reaction zone effluent stream is continued through line 1 to provide about 271.4 moles of propane, 2721.4 moles of isobutane, 649.9 moles of n-butane, 29.4 moles of isopentane, 1.3 moles of n-pentane and about 394.6 moles of C6 + hydrocarbons per hour to the isostripper column 3. Said alkylation reaction zone effluent stream further contains about 125.7 moles of HF per hour, the mole quantities expressed herein being intended as lb-moles. of from about 350° to about 390° F. of from about 125° to about 150° F. at a temperature of about 100° F., is charged to a heat exchanger 2 recovered from the isostripper column by way of line 27 The alkylation reaction zone effluent stream
