Ethylene and propylene, the simplest alkenes, are the two most important organic chemicals produced industrially. Approximately 26 million tons of ethylene and 17 million tons of propylene are produced each year in the United States for use in the synthesis of polyethylene, polypropylene, ethylene glycol, acetic acid, acetaldehyde, and a host of other substances (Figure 6.11.

The use of 2-vinyldioxolane, the ethylene glycol acetal of acrolein, as a dienophile illustrates application of the masked functionality concept in a different way. The acetal itself would not be expected to be a reactive dienophile, but in the presence of a catalytic amount of acid the acetal is in equilibrium with the electrophilic oxonium ion. [Pg.493]

Similar reactivity is realized with 2-acetylthiophene using triethylsilane with aluminum chloride.259 Treatment of the ethylene glycol acetal of 2-thiophenecar-baldehyde with Et3SiH/TFA results in reduction of the ring and oxidation of the side chain to the silylated carboxylic acid (Eq. 119),260 whereas similar treatment of 2-thiophenecarbaldehyde gives 2-methyltetrahydrothiophene and 2-...

No evidence of ruthenium metal formation was found in catalytic reactions until temperatures above about 265°C (at 340 atm) were reached. The presence of Ru metal in such runs could be easily characterized by its visual appearance on glass liners and by the formation of hydrocarbon products (J/1J) The actual catalyst involved in methyl and glycol acetate formation is therefore almost certainly a soluble ruthenium species. In addition, the observation of predominantly a mononuclear complex under reaction conditions in combination with a first-order reaction rate dependence on ruthenium concentration (e.g., see reactions 1 and 3 in Table I) strongly suggests that the catalytically active species is mononuclear.

The three examples related to solvent replacement cover the generation and evaluation of solvent alternatives for Ethyl Glycol Acetate, Ethyl Glycol and Methylene Chloride. Where feasible, the selected solvent alternatives have been tested under conditions of industrial application and/or laboratoiy scale experiments with very encouraging results. [Pg.88]

The above solution procedure has been applied to find replacement solvents for the following solvents Ethyl Glycol Acetate, Ethyl Glycol and Methylene Chloride. These three solvents are extensively used in the paints and ink industry, although, recent studies have shown that they carry an appreciable environmental burden in addition to being found harmful for the health of the people exposed to them (for example, employees in the manufacturing plants and/or consumers).

If the additional substance stays in the residue, the process is called extractive distillation of aqueous solutions. The separations of various alcohols, ethylene glycol, acetic acid, acetone, and nitric acid from water is an example in which extractive distillation has been used or proposed.
