The stream of CHP primarily having cumene hydroperoxide therein but also containing DMBA, acetophenone, and various organic acids as well as other materials is brought to a cleavage reactor having a sulfuric acid catalyst in the quantity of about 250 parts per million of sulfuric acid per weight of composition mass. Products of decomposition of cumene hydroperoxide are methylstyrene, acetophenone, and cumyl alcohol. The condensed material is discharged from condenser 39 to a line 41 at the rate of 103 pounds per hour. 4. of mercury. A process for separating cumene from cumene hydroperoxide which comprises heating a mixture of said compounds containing about 10 to about 50% of the hydroperoxide to a temperature in the order of about 200 F combining the heated mixture with steam in the amount of about 10 to about 25% by weight, passing the mixture and steam into a fractionation zone wherein a temperature of about 150 to about 200 F. and a pressure of about 100 to about 150 mm. Having thus provided a description of our invention along with specific examples thereof, it should be understood that no undue limitations or restrictions are to be imposed by reason thereof, but that the present invention is defined by the appending claims. Cumene is air oxidized in presence of Cobalt naphthenate in alkaline medium to form cumene hydroperoxide ,which on heating in presence of dilute sulphuric acid form phenol along with acetone. With regard to the separation of unreacted hydrocarbon from cumene hydroperoxide in the fractionation zone, a temperature of about 150 to about 200 F. is employed. (Cl. <> The presence of byproduct materials tends to obscure the separation of the hydroperoxide from the unreacted hydrocarbon. From a commercial standpoint, it is important to select the operating pressure of this separating zone so as to insure the subsequent condensation of steam and unreacted hydrocarbon at about the ambient temperature of Water, which can be used for indirect cooling of the overhead product from the separating zone. Linear Formula C 6 H 5 C(CH 3) 2 OOH . 202-46) This invention relates to a process for the separation of dialkylarylmethyl hydroperoxide from dialkylarylmethane, and more particularly, it is concerned with a method of separating cumene hydroperoxide from cumene. The pressure in the accumulater 23 is maintained at 80 mm. The steam and vaporized unreacted hydrocarbon material are discharged from the stripping zone, and they are usually passed into the fractionation zone for treatment in accordance with the procedure described above. Specific examples of the hydroperoxides are cumene hydroperoxide, cymene hydroperoxide, a,a-dimethylphenylmethyl hydroperoxide, a,a-methylethylphenylmethyl hydroperoxide, a,a-diethylphenylmethyl hydroperoxide, etc. As a result of the quantity of steam used with the feed material and the temperature and pressure existing in the fractionation zone, there remains a liquid material in the separation zone containing a substantial portion or a major amount of the hydroperoxide and a small quantity or a minor amount of the hydrocarbon. of mercury to about 756 mm. The uncondensed overhead product is removed from the top of accumulator 23 by means of a line 27, and it is then passed to a separating drum 29. Specific examples of the unreacted hydrocarbon can be any one of the starting compounds from which the just enumerated hydroperoxides are derived. 390,626. The overhead vapors pass from line 17 to a condenser 19 wherein the temperature is reduced to 100 F., and thereby a substantial part of the material is liquefied. %�쏢 Other objects and advantages of this invention will become apparent from the following description and explanation thereof. The combined streams of feed and steam passed through a line 9 prior to entering a heating element 11 wherein the temperature is raised to 200 F. The heated mixture of steam and feed pass from the heating element 11 to a line 13, and thence, it is introduced into the bottom part of the fractionation section A of a tower 15. By this practice, it is to be noted that the quantity of steam which is present in the fractionation zone is enhanced by the quantity of steam which is added to the stripping zone for the purposes described above. PubChem Substance ID 24854872. Generally, the overhead product from the fractionation zone contains about 0.5 to about of dialkylarylmethyl hydroperoxide, more usually about 0.5 to 1.5% of the same, and the remainder is comprised of substantially all of the dialkylarylmethane compound and small amounts of acetophenone and dimethylbenzyl alcohol. 2. Phenol comes from cleavage of CHP, but in the … While this technique is not as economical as using water which exists at an ambient temperature as the cooling medium, nevertheless, it is within the scope of the present invention.
