Tetraethyltin

Tetraethyltin or tetraethyl tin is a chemical compound with the formula (CH3CH2)4Sn, that is, a tin atom attached to four ethyl groups.

It is an important example of an organotin compound, often abbreviated as TET.

Tetraethyltin is a colourless flammable liquid, soluble in diethyl ether and insoluble in water, that freezes at −112 °C and boils at 181 °C.

Tetraethyltin can be obtained by reacting ethylmagnesium bromide with tin(IV) chloride:[1] The same reaction can be used to obtain tetra-n-propyltin and tetra-n-butyltin.

[1] Tetraethyltin is converted in the body to the more toxic triethylstannylium ions.

E.g. chlorine gas Flammability 2: Must be moderately heated or exposed to relatively high ambient temperature before ignition can occur. Flash point between 38 and 93 °C (100 and 200 °F). E.g. diesel fuel Instability 3: Capable of detonation or explosive decomposition but requires a strong initiating source, must be heated under confinement before initiation, reacts explosively with water, or will detonate if severely shocked. E.g. hydrogen peroxide Special hazards (white): no code
