Mercury incompatibilities with

DIETHAMINE (109-89-7) Forms explosive mixture with air (flash point - 18°F/—28°C). A strong organic base. Reacts violently with oxidizers. Violent reaction with acids, mercury. Incompatible with alcohols, acrylates, aldehydes, alkali metals, alkylene oxides, caprolactam solution, cellulose nitrate, cresols, epichlorohydrin, glycols, isocyanates, ketones, organic anhydrides, phenols, substituted allyls, vinyl acetate. Attacks aluminum, copper, lead, tin, zinc, and their alloys. Flow or agitation of substance may generate electrostatic charges due to low conductivity. 

Low-pressure mercury and sodium arcs, as well as fluorescent tubes [2,3] of technical importance are necessarily extended light sources because their mode of operation is incompatible with compression of the source to a point without alteration of their emission spectra. 

The advantages of the liquid surface and large overpotential for hydrogen evolution make mercury the material of choice for cathodic processes, unless the use of mercury is specifically contraindicated by some incompatibility with the system. Incompatibility can arise from strong specific absorption, as with some sulfur-containing compounds, or in high-temperature systems such as fused salts because of the low boiling point of mercury (356.6°C). 

SAFETY PROFILE Poison by intraperitoneal route. Moderately toxic by ingestion. Incompatible with nonmetal oxides. When heated to decomposition it emits toxic fumes of Hg. See also MERCURY COMPOUNDS. 

DOT CLASSIFICATION 6.1 Label Poison SAFETY PROFILE Poison by ingestion, subcutaneous, intravenous, and intraperitoneal routes. Human systemic effects by ingestion nausea or vomiting, hypermotility, diarrhea, kidney changes, somnolence. Hydrolyzes to toxic fumes. A friction- and impact-sensitive explosive. It may initiate detonation of liquid hydrogen cyanide. Incompatible with fluorine, magnesium, sodium nitrite. When heated to decomposition it emits very toxic fumes of Hg, NO, and CNT See also CYANIDE and MERCURY COMPOUNDS. 

SAFETY PROFILE A poison. Flammable by chemical reaction an oxidizer. Explosive reaction with hydrogen peroxide, chlorine + ethylene. Reacts violently with molten potassium, molten sodium, S, (H2S + BaO + air). Forms explosive mixtures with nonmetals [e.g., phosphorus (impact-sensitive), sulfur (friction-sensitive)]. Incompatible with alkali metals, reducing materials. Dangerous when heated to decomposition it emits highly toxic fumes of Hg. See also MERCURY COMPOUNDS, INORGANIC. 

When pure (dry) it does not attack glass or mercury at normal temperatures. Can react violently with NH3, CO, diborane, H2, H2S, CH4, tetrafluorohydrazine. Can react vigorously with reducing materials. Particularly hazardous under pressure. Incompatible with charcoal, hydrogen-containing compounds, tetrafluorohydrazine. When heated to decomposition it emits highly toxic fumes of F. See also FLUORIDES. 

Carboxymethylcellulose sodium is incompatible with strongly acidic solutions and with the soluble salts of iron and some other metals, such as aluminum, mercury, and zinc. Precipitation may occur at pH <2, and also when it is mixed with ethanol (95%). 

Discoloration or precipitation may occur with iodides, mercury salts, phenolic substances, salicylates, sulfonamides, and tannins. Polyoxyethylene alkyl ethers are also incompatible with benzocaine, tretinoin and oxidizable drugs. ... 

Incompatible with quaternary compounds, gelatin, ferric salts, calcium salts, and salts of heavy metals, including silver, lead, and mercury. Preservative activity may be reduced by interactions with kaolin or nonionic surfactants. 

Hyoscyamine and the sulfate salt are incompatible with alkalis, mercury salts and tannic acid, while hyoscyamine hydrobromide is incompatible with alkalis, silver salts and tannic acid (54).
