General Description
DIPHENYLMETHYL BROMIDE(776-74-9) is a white crystalline solid. Melting point 113°F. A lachrymator. In the presence of moisture corrosive to tissue and most metals.
Reactivity Profile
Halogenated aliphatic compounds are moderately or very reactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Materials in this group are incompatible with strong oxidizing and reducing agents. Also, they are incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.
Air & Water Reactions
Insoluble in cold water. Decomposed by hot water to give corrosive hydrobromic acid.
Health Hazard
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard
Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
Chemical Properties
ORANGE-RED TO ORANGE-BROWN LOW MELTING SOLID
Synthesis
In a 250mL three-necked flask, 33.6g (0.2mol) of diphenylmethane, 8g (0.2mol) of sodium hydroxide were added and heated to an internal temperature of 95-105 °C. Slowly add bromine 33.6kg (0.21mol) dropwise, dropwise completion, hold at 100-110°C for 3 hou
