Hoechst Celanese Alcohols

Formaldehyde. Pure formaldehyde, CH2O, is a colorless, pungent smelling reactive gas (see Formaldehyde). The commercial product is handled either as soHd polymer, paraformaldehyde (13), or in aqueous or alcohoHc solutions. Marketed under the trade name Formcel, solutions in methanol, / -butanol, and isobutyl alcohol, made by Hoechst-Celanese, are widely used for making alcohol-modified urea and melamine resins for surface coatings and treating textiles. 

The Boots Hoechst Celanese (BHC) ibuprofen process involves palladium-catalyzed carbonylation of a benzylic alcohol (IBPE). More recently, we performed this reaction in an aqueous biphasic system using Pd/tppts as the catalyst (Figure 9.6 tppts = triphenylphosphinetrisulfonate). This process has the advantage of easy removal of the catalyst, resulting in less contamination of the product.

Many other metal ions have been reported as catalysts for oxidations of paraffins or intermediates. Some of the more frequently mentioned ones include cerium, vanadium, molybdenum, nickel, titanium, and ruthenium [21, 77, 105, 106]. These are employed singly or in various combinations, including combinations with cobalt and/or manganese. Activators such as aldehydes or ketones are frequently used. The oxo forms of vanadium and molybdenum may very well have the heterolytic oxidation capability to catalyze the conversion of alcohols or hydroperoxides to carbonyl compounds (see the discussion of chromium, above). There is reported evidence that Ce can oxidize carbonyl compounds via an enol mechanism [107] (see discussion of manganese, above). Although little is reported about the effectiveness of these other catalysts for oxidation of paraffins to acetic acid, tests conducted by Hoechst Celanese have indicated that cerium salts are usable catalysts in liquid-phase oxidation of butane [108].

The formation of C-C bonds is of key importance in organic synthesis. An important catalytic process for generating C-C bonds is provided by carbonylation. Most carbonylation reactions have a good atom economy, because most reagent atoms are transferred to the product. Therefore, there are some applications of carbonylation processes in fine chemistry, too. For example, the analgesic ibuprofen is produced by Hoechst-Celanese by carbonylation of a substituted alcohol with 100% atom efficiency according to Eq. (8-20) [7] ...

The glycol ethers formed by reaction of an alcohol or phenol with ethylene or propylene oxide to yield a solvent with both an alcoholic and ether functional groups are discussed in Chapter 13. Major producers of the alcoholic solvents include BASF Corporation, Eastman Chemical Company, Exxon Chemical Company, Hoechst Celanese Company, Shell Chemical Company, and Union Carbide Corporation. This chapter will discuss the naming nomenclature for the alcohols, their physical properties, the various industrial uses, possible environmental concerns, and the safe handling of the alcohols. 

The chemistry and uses of formaldehyde has been described [1]. Formaldehyde is sold as aqueous solutions which contain minor amounts of methanol. Water-free solutions of formaldehyde dissolved in alcohols like methanol or n-butanol are also available from Hoechst Celanese as Formcel solutions.
