2,2,3-TRIMETHYLBUTANE Chemical Properties,Uses,Production
Description
2,2,3-Trimethylbutane (i.e., triptane) is a potential gasoline octane booster with a research octane number (RON) of 112. it is also used as a fuel additive and in comparative rate of thermal decomposition (CRTD) single-pulse surge tube studies[1-2].
Chemical Properties
Colorless liquid. Soluble in alcohol; insoluble in water.
Uses
Organic synthesis, aviation fuel.
Preparation
2,2,3-Trimethylbutane (triptane) selectively forms from dimethyl ether at low temperatures on acid zeolites[3].
We report herein the first selective catalytic conversion of DME to
triptane on halide-free catalysts,
specifically on crystalline solid
acids, at much lower reaction temperatures (453–493 K) and higher
DME pressures (60–250 kPa) than
in established methanol/DME to
hydrocarbon processes. Low temperatures avoid intervening skeletal
isomerization and b-scission of triptyl chains or their precursors. These
processes would otherwise occur
before the methylation events that
form the C7 chains containing the
triptane backbone, which desorb irreversibly as triptane.
Synthesis Reference(s)

Hazard
Flammable, moderate fire risk.
