Carboxylic acids halogenated, acidity

Firedamp-proof Detonators. Firedamp-proof detonators have net received tht attention that firedamp-proof expls have, possibly because the expln of the, detonator is lost in the immediately succeeding expln of the main charge. Treatment of the detonator charge in caps follows similar lines to treatment of Dynamites in the addition of cooling additives, such as salts or wax (Ref 1), BuOAc (butyl acetate) (Ref 2), or poly car boxy lie acids, oxygenated poly carboxylic acids, halogen substituted poly carboxylic and oxygenated polycarboxylic acids, and the neutral and acid salts of these (Ref 4)... 

Chemically, the triarylmethane dyes are monomethine dyes with three terminal aryl systems of wind] one or more arc substituted with primary, secondary, or tertiary amino groups or hydroxyl groups in the para position to the methine carbon atom. Additional substituents such as carboxyl, sulfonic acid, halogen, alkyl, and alkoxy groups may be present on the aromatic rings. The number, nature, and position of these substituents determine both the hue or color of the dye and the application class to which the dye belongs. 

They are often blended into compounds that are developed for injection molding applications. Where such an additive is absent, molded components tend to stick to mold surfaces. To prevent this, mold surfaces must be treated between every cycle, or they can be coated with a range of semipermanent mold release treatments. Inclusion of an internal release agent prevents mold surface build-up, surface charring, and simplifies production. Internal mold release agents may include hydrocarbons, alcohols, carboxylic acids, halogenated compounds, ketones, carboxylic acid esters, amides, metal salts, and silicone compounds. 

The Perkin reaction is capable of numerous modifications, since in place of benzaldehyde, its homologues, its nitro- and oxy-derivatives, etc., may be used. On the other hand, the homologues of sodium acetate may be used as has been pointed out. The condensation in these cases always takes place at the carbon atom adjoining the carboxyl group. Halogen substituted aliphatic adds will also react thus from benzaldehyde and chloracetic add, chlordnnamic acid is obtained ... 

When carboxylate salts react with acid halogens or their solutions, carboxylic acids are formed. 

ETFE is inert to strong mineral acids, halogens, inorganic bases, and metal salt solutions. Carboxylic acids, aldehydes, aromatic and aliphatic hydrocarbons, alcohols, ketones, esters, chlorocarbons, and classic polymer solvents have little effect on ETFE. Tefzel is also weather resistant and ultraviolet ray resistant. 

Listing of triorganotin carboxylates of halogen substituted carboxylic acids concludes in Table 201. 

Carboxylations of halogen compounds include the technically useful conversion of chloroacetate to malonate (eq 15), and several patent reports of quantitative conversion of Benzyl Chloride to phenylacetic acid. The incorporation of two molecules of carbon monoxide to give a-keto-acids, as exemplified by the reaction of benzyl chloride (eq 16), is remarkably solvent-dependent and almost certainly involves reaction of the halide with Co(CO)4 .
