Tert- amyl methyl ether (TAME) is an aliphatic ether thatsmells like camphor andhas gained technical importancebecause of its use as an additive in petrol and also as a solvent in organic chemistry .

Manufacturing

The ether is produced by the acid-catalyzed addition of methanol to 2-methylbut-1-ene or 2-methylbut-2-ene ( isopentene ). Acid ion exchangers are used as the catalyst .

The production volume in the EU is between 100,000 and 1 million tons per year .

properties

The flash point of tert -amyl methyl ether is approx. −18 ° C, the ignition temperature is 345 ° C and the explosion limits are between 1.18% (lower explosion limit) and 7.1% (upper explosion limit).
