Patent number: 8247616Abstract: A method of producing phenol, acetone and alpha-methyl styrene. A mixture of cumene hydroperoxide and dimethylbenzyl alcohol is provided. The mixture is subjected to a first stage reaction in the presence of about 0.5 to 1.5 wt. % water and about 20 to 400 ppm sulfuric acid at a reactor pressure of about 450 to 760 mm Hg, a temperature of about 60 to 85° C., and a residence time of 4 to 45 minutes to produce a composition having an acetone to phenol mole ratio of about 1 to 1.5. The composition is subjected to a second stage reaction in the presence of about 0.5 to 3 wt. % additional water with a second stage reactor temperature of about 110 to 150° C. and a residence time of 0.5 to 30 minutes.Type: GrantFiled: March 28, 2012Date of Patent: August 21, 2012Assignee: Honeywell International Inc.Inventors: Scott R.

Patent number: 7186866Abstract: Products from the decomposition of cumene hydroperoxide (CHP) are recovered by distillation. The majority of the undesirable by-product acetol (hydroxyacetone) is removed from the phenol stream by distillation wherein the majority of the acetol is carried with an overheads stream comprising acetone, cumene and alphamethylstyrene (AMS). Acetol is subsequently separated from acetone by distillation wherein acetone is taken as an overheads stream and acetol remains with a bottoms stream comprising cumene, AMS and phenol. The acetol, along with residual phenol, is extracted from the cumene and AMS by counter-current washing with an aqueous alkali metal hydroxide. The phenol stream is then distilled to separate phenol from cumene, alphamethylstyrene and higher boiling compounds. The phenol, containing only a small amount of acetol, can then be treated to remove methylbenzofuran by treatment with an acidic resin or solid superacid catalyst without formation of significant amounts of additional methylbenzofuran.Type: GrantFiled: November 14, 2005Date of Patent: March 6, 2007Assignee: Sunoco, Inc. (R&M)Inventors: Scott R. Keenan, Amber R. Harach, James G. Skipworth

Patent number: 6620980Abstract: An improved method for the recovery of phenol from aqueous streams comprises adding a relatively non-polar solvent to a phenol containing aqueous stream to improve the separation of the phenol form the aqueous stream.

Patent number: 6388144Abstract: A process for treating phenol with a strong acid ion exchange resin to reduce the level of methylbenzofuran is provided. The process is capable of being carried out at elevated temperatures for extended periods, such that cooling of the phenol from distillation temperatures prior to the resin treatment is not required. The process can reduce or eliminate the substantial costs associated with conventional processes that require cooling and re-heating the phenol.Type: GrantFiled: June 15, 2001Date of Patent: May 14, 2002Assignee: Sunoco, Inc. (R&M)Inventors: Tilak P. Wijesekera, Scott R. Keenan
