This example illustrates the preparation of a typical heteropoly acid-on-titania catalyst.

(b) A substantial portion of the 2-phenyl-2-propanol in the feed is also converted to product.

The mixture was then rotary evaporated to remove excess liquid and calcined at 150°-350° C. in a stream of nitrogen. Employing the reactor and procedures of Example 15, 150 cc of 12-molybdophosphoric acid-on-titania were pretreated with acetone (150 cc/hr) at 60° C., then fed a mixture of "80%" cumene hydroperoxide (900 g, composition as in Example 1) diluted with acetone/cumene/phenol (6.4:2.4:9.1 weight ratio 0.2100 g) at a feed rate of 150 cc/hr. No. It may also be noted from a review of the data in Table I that: (1) Resins such as DUOLITE® C-467 having the phosphoric acid functionality are not effective for the desired cumene hydroperoxide decomposition reaction to phenol/acetone (See Example 12) under these screening conditions.

No. A method is disclosed for the synthesis of phenol and acetone by decomposition over a heterogeneous catalyst from the group consisting of a heteropoly acid on an inert support or an ion exchange resin with a sulfonic acid functionality. (a) The estimated yield of phenol, based on cumyl hydroperoxide charged, is: 98 mole %. Weight of recovered, yellow, extrudates was 252 g. The data in Example 1 illustrate the quantitative conversion of cumene hydroperoxide to phenol/acetone catalyzed by tungstophosphoric acid on titania catalyst of Example A.

No. ASSIGNMENT OF ASSIGNORS INTEREST;ASSIGNOR:HUNSTMAN CORPORATION;REEL/FRAME:007986/0353, Owner name: BANKERS TRUST COMPANY, ILLINOIS, Free format text: Atoms coordinated to the heteroatom via oxygens are called polyatoms (W in the case of Equation 2) and in most cases are any one of such limited species as molybdenum, tungsten, niobium and vanadium. (2) Other acidic catalysts such as phosphoric acid-on-titania and boric acid, prepared by methods similar to that of Example A, are far less effective for cumene hydroperoxide conversion to phenol/acetone (Examples 13 and 14). Again it is disclosed that the decomposition can be promoted by the addition to the residue of acids such as sulfuric acid, phosphoric acid or sulfonic acids, as well as acid washed activated earth, such as Fuller's earth.
