Catalyst 07
Catalyst 07 : Chemistry and Chemical Disasters. A substance that changes the speed of a chemical reaction but that undergoes no permanent change itself. In respirator use, a substance that converts a toxic gas (or vapor) into a less toxic gas (or vapor). Usually catalysts greatly increase the reaction rate, as in conversion of petroleum to gasoline by cracking. In paint manufacture, catalysts, which hasten film-forming, sometimes become part of the final product. In most uses, however, they do not, and can often be used over again
