This reaction is quite useful because the mixture of product gases, called water gas, is an excellent industrial fuel. In the commercial preparation of water gas, the chemical engineer must allow for the absorption of heat during the reaction. In fact, he must periodically turn off the steam and reheat the coal to keep the reaction going. To aid the engineer, we might measure 108... 

The migration of oxide ion is mainly accelerated by lattice vacancies. Knowledge of how to introduce such vacancies into the catalyst by the substitution of part of a component metal cation for another one having a different valence is widely realized for the preparation of excellent industrial oxidation catalysts. 

Some esters have characteristic fruity smells and are generally used as excellent industrial solvents. Esters like ethyl ethanoate, also called ethyl acetate, are used as a solvents for glues. It is this compound that glue sniffers love. Unfortunately they do not realize that it kills off brain cells and can eventually lead to death. 

The following review is an excellent industrial prospective on these three methods S. Kotha, Tetrahedron 1994, 50, 3639-3662. 

These products are excellent industrial wetting agents and are manufactured in quantity. A detailed description of the commercial procedure is given on p. 376. A variation of this reaction involves a similar addition of bisulfite to compounds of the type RCOCH=CHCOOR, where R is derived from a long-chain alkylated benzene and R from a long-chain alcohol. 

Investigations in this area with polymer-bound catalysts are rather limited. This modest interest is due, in part, to the fact that excellent industrial routes to large-volume carboxylic acids already exist. One aspect that would... 

Many specialty fibers have been developed over the years for special end- uses. An example of excellent industrial accomplishment is the development of TRIAD fiber shown in Figure 2.19. Used in FRAM automotive air filter, the TRIAD fiber helps trap dirt inside its microscopic channels that in turn trap more dirt without increasing the air flow restriction. Another example is the preparation of a conductive fiber using the bicomponent fiber technology with a built-in conductive fiber. Figure 2.42, Item 29, shows a fiber cross-section where the dark-colored portion of the fiber is the conductive portion.
