Dicyclohexylammonium nitrite Usage And Synthesis

Description

Dicyclohexylamine nitrite is a flammable whitepowder which has some volatility at room temperature andhigher. Molecular weight=228.38; Melting point=181℃;Flash point=185℃. Partly soluble in water.

Chemical Properties

Dicyclohexylamine nitrite is a flammable white powder which has some volatility at room temperature and higher

General Description

A white to light-colored crystalline solid. Insoluble in water and denser than water. Contact may cause irritation to skin, eyes, and mucous membranes. May be toxic by ingestion. Used to make other chemicals.

Air & Water Reactions

Highly flammable. Dicyclohexylammonium nitrite may be sensitive to prolonged exposure to air. . Insoluble in water.

Reactivity Profile

An oxidizing agent but can serve as a reducing agent. If mixed with reducing agents, including hydrides, sulfides and nitrides, may begin a vigorous reaction that culminates in a detonation.

Health Hazard

Fire may produce irritating and/or toxic gases. Contact may cause burns to skin and eyes. Contact with molten substance may cause severe burns to skin and eyes. Runoff from fire control may cause pollution.

Fire Hazard

Flammable/combustible material. May be ignited by friction, heat, sparks or flames. Some may burn rapidly with flare burning effect. Powders, dusts, shavings, borings, turnings or cuttings may explode or burn with explosive violence. Substance may be transported in a molten form at a temperature that may be above its flash point. May re-ignite after fire is extinguished.

Safety Profile

Poison by ingestion and subcutaneous routes. Questionable carcinogen with experimental tumorigenic data. A flammable liquid. When heated to decomposition it emits very toxic fumes of HN02 and NOx. See also NITRITES.

Potential Exposure

It is used as a vapor-phase corrosion inhibitor whereby it vaporizes either from the solid state or from solution, and offers protection against atmospheric rusting. Wrapping paper, plastic wraps; and other materials may be impregnated with dichan to protect metal parts during packaging and storage

First aid

Skin Contact: Flood all areas of body thathave contacted the substance with water. Do not wait toremove contaminated clothing; do it under the water stream.Use soap to help assure removal. Isolate contaminatedclothing when removed to prevent contact by others.Eye Contact: Remove any contact lenses at once. Immediatelyflush eyes well with copious quantities of water or normalsaline for at least 20-30 min. Seek medical attention.Inhalation: Leave contaminated area immediately; breathefresh air. Proper respiratory protection must be supplied toany rescuers. If coughing, difficult breathing, or any othersymptoms develop, seek medical attention at once, even ifsymptoms develop many hours after exposure.Ingestion: Contact a physician, hospital, or poison center atonce. If the victim is unconscious or convulsing, do notinduce vomiting or give anything by mouth. Assure that thepatient’s airway is open and lay him on his side with hishead lower than his body and transport immediately to amedical facility. If conscious and not convulsing, give aglass of water to dilute the substance. Vomiting should notbe induced without a physician’s advice.Note to physician: Treat for methemoglobinemia.Spectrophotometry may be required for precise determination of levels of methemoglobinemia in urine.

storage

Color Code—Red: Flammability Hazard: Store ina flammable materials storage area. Prior to working withthis chemical you should be trained on its proper handlingand storage. Store in a refrigerator under an inert atmosphere for long-term storage.

Shipping

UN2687 Dicyclohexylammonium nitrite, Hazard Class: 4.1; Labels: 4.1-Flammable solid.

Incompatibilities

Highly flammable and a strong oxidizer. Contact with reducing materials (nitrides, hydrides, sulfides, etc.) or easily oxidized materials may cause fire and explosion hazard

Waste Disposal

Incineration; incinerator equipped with a scrubber or thermal unit to reduce nitrogen oxides emissions.
