Application No. 08/189,899
heating said dispersion to a temperature of about
50°C to 200°C to form a first reaction product
solution;
reacting said first reaction product with an oxirane
to form a second reaction product;
recovering said second reaction product;
nitrating said recovered second reaction product to
produce a nitro-ester compound; and
recovering said nitro-ester compound.
24. A fuel for an internal combustion engine comprising
at least one C -C alkyl alcohol; and
1 6
an ignition promoter prepared by the process of:
forming a dispersion of a sugar in a lower alcohol,
lower ketone or mixture thereof 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 said second reaction product;
nitrating said recovered second reaction product to
produce a nitro-ester compound; and
recovering said nitro-ester compound.
31. A process for preparing an ignition promoter
comprising:
forming a dispersion of a sugar in the presence of
an acid catalyst in a polar medium selected from the
group consisting of lower alcohols and lower
ketones;
heating said dispersion at a sufficient temperature
to form a first reaction product solution;
reacting said first reaction product solution 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.
