Appeal No. 1997-3337
Application No. 08/189,899
BACKGROUND
The invention is drawn to an ignition promoter, a process
for producing an ignition promoter and to a fuel containing
the ignition promoter produced according to the process of the
invention. The ignition promotor is said to be a nitro-ester
compound produced by (1) heating a dispersion of a sugar in
lower alcohol, e.g. methanol or ethanol, in the presence of an
acid catalyst to form a first reaction product solution, (2)
reacting the first reaction product with an oxirane to form a
second reaction product, and (3) nitrating the second reaction
product to produce a nitro-ester compound. (Specification
page 5 line 16 to page 8, line 15). Representative claims 1,
17, 24 and 31 are reproduced below:
1. A process for preparing an ignition promoter
comprising:
forming a dispersion of a sugar in methanol or
ethanol in the presence of an acid catalyst;
heating said dispersion at a sufficient temperature
to form a first reaction product solution;
reacting said first reaction product with an oxirane
to form a second reaction product;
recovering the second reaction product;
nitrating said recovered second reaction product to
produce a nitro-ester compound; and
recovering said nitro-ester compound.
17. An ignition promoter compound prepared by the
process of:
forming a dispersion of a sugar in a lower alcohol or
lower ketone in the presence of an acid catalyst;
