Allied Chemical and Dye Corp

Donaldson, R.D. etal U.S. Patent 2,767,223 October 16, 1956 assigned to Allied Chemical and Dye Corp. 

This is a simple method that gives good yields of LSD with very little (if any) iso-LSD. You will be required to purchase sulfur trioxide from Allied Chemical and Dye Corp (ask for Sulfan B, or SQ3), but this is not a suspicious chemical so ordering is not a problem.

Sulfur trioxide, SOj. Mol. wt 80.07, m.p. 17°, b.p. about 45°. This reagent is available from the General Chemical Division, Allied Chemical and Dye Corp., under the name Sulfan B, a -y-form stabilized with an inhibitor to prevent polymerization. It is used in organic work chiefly in the form of complexes with dioxane, dimethylformamide, and pyridine. 

Manufacturers Literature. The manuals, technical bulletins, and reports issued by the Calco Chemical Division, American Cyanamid Co. Ciba Co. Sandoz Chemical Works E. I. du Pont de Nemours Co. General Dyestuff Corp. Division of General Aniline Geigy Go. Inc. National Aniline Division, Allied Chemical and Dye Corp. and Imperial Chemical Industries are valuable sources of information on new dyes and applications. There are other companies that publish literature equally as valuable and useful. 

Phenol. The manufacture of phenol by the oxidation of benzene is described by Denton (21) and by Simons and McArthur (107). The literature on phenol by the oxidation of cumene is partly covered in the reports of Frank (33), Hawkins (43), and Kharasch (57), mentioned earlier. A brief description and flow sheet of the process is given in Chemical Engineering (16). The patents in this field are mainly held by The Distillers Co., Ltd., Hercules Powder Co., and Allied Chemical and Dye Corp. In this phenol process large amounts of acetone are obtained as a coproduct. It should also be noted that the process may be directed to the production of cumene hydroperoxide and a,a dimethylbenzyl alcohol. Krieble (61) and Kenyon and Boehmer (55) describe the preparation of phenol by the chlorination and sulfonation processes.
