Acetone chlorination

Boron nitride is one of the most outstanding corrosion-resistant materials. It is inert to gasoline, benzene, alcohol, acetone, chlorinated hydrocarbons and other organic solvents. It is not wetted by molten aluminum, copper, cadmium, iron, antimony, bismuth, silicon, germanium, nor by many molten salts and glasses. It is used extensively as crucible material, particularly for molten metals, glasses and ceramic processing. 

To overcome problems with VX, a reaction with silver fluoride impregnated on a filter in front of the adsorption tube has been applied. The fluoride converts VX to the more volatile ethyl methylphos-phonofluoridate (CAS 673-97-2), which is more amenable to GC (37). In an alternative approach, adsorption tubes can be extracted with a suitable solvent such as ethyl acetate or acetone (chlorinated solvents may dissolve the polymeric adsorption material). This offers the advantage of a repeat analysis. To compensate for the loss of sensitivity, compared with thermodesorption, on-column... 

PVC is resistant to nonpolar (hydrocarbon) and strongly polar substances (water, inorganic acid). Middle polarity compounds such as cyclohexanone, dimethylforma-mide, acetone, chlorinated hydrocarbons, tetrahydrofuran, and phenol all either swell PVC or dissolve it. This behavior can easily be attributed to the slightly polar structure of the PVC macromolecule. 

Properties All are basic polypeptides. Soluble in water the hydrochlorides are soluble in water and methanol, insoluble in ether, acetone, chlorinated solvents, and hydrocarbons. Permissible food additives.
