As lactams of 4-amino-3-oxobutanoic acids, tetramic acids react with amines (87JPJ858) and with phenylhydrazine. The latter reaction is catalyzed with para-toluenesulfonic acid. Thus, for example, l/2b give phenyl-hydrazone 65 in 80% yield that, in turn, under the conditions of the Fischer indole synthesis, may give rise to pyrrolo[4,3-b]indolene 66 (90TH1).

The emission characteristics of E85 vehicles are not as well documented as for M85 vehicles however, Ford tested E85 in their 1996 model Taurus flexible fuel vehicle and found essentially no difference in tailpipe emissions compared to using the standard emissions testing gasoline (Indolene). In this test, the engine-out emissions of HC and NOx were lower than for gasoline, but ethanol s lower exhaust gas temperatures were believed to decrease catalyst efficiency slightly...

Four unleaded fuels were selected for the octane evaluation program. The fuels ranged from a regular grade of leaded gasoline without the tetraethyl lead to Indolene high octane, the unleaded fuel used for emissions certification. Indolene is the trade name for the test fuel manufactured by Standard Oil Co. to meet the specification called out in Ref. 7. Some of the base fuel properties are given in Table I. 

Data were taken for four different fuels over the complete range of test conditions. The fuels were base fuels C and D and each of these base fuels plus 10% methanol. As noted in Table I, base fuel D is unleaded Indolene, the reference fuel specified for federal emissions tests. 

Figure 7 reveals that the addition of 10% methanol to Indolene does not substantially alter the HC emissions. The effect of spark retard is...
