Title: Anti-knock motor fuels contg. alcohols - with addn. of acetals, esters, iron carbonyl and soluble manganese cpds.
Inventor: KUEHN MARTIN PROF DR PHIL
IPC: C10L1/10
Filed: 1974-10-04
Abstract: Anti-knock motor fuels contain alcohols, esp. methanol, together with acetals and esters, esp. of methanol, with addn. of iron carbonyl and organic cpds. of Mn soluble in the fuel. The combination of combustion-initiating acetals and oxidn.-catalysing Mn cpds. gives reliable ignition over all practical air-fuel ratios. The controlled weakening of the mixt. by the xygen content of the methanol and its acetals and esters reduces formation of CO during combustion and prevents formation of carcinogenic polycyclic aromatic hydrocarbons. Combustion temp. can be kept low enough to prevent formation of nitrogen oxides. The methanol and other intermediates e.g. formaldehyde, acetaldehyde, formic and acetic acids, can be obtained from sources other than petroleum.
