| 2,2,3-TRIMETHYLBUTANE Usage And Synthesis |
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.
