Abstract
A process for preparing the ignition promoter comprises combining a sugar with selected solvents and heating to form a stable solution, reacting the resulting solution with an oxirane and thereafter reacting the resulting product with nitric acid under nitrating conditions. A fuel for use in compression ignition engines contains a lower alcohol and about 0.15 to 30 wt % of the ignition promoter.
Claims25
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.
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.
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;
- 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.
A fuel for an internal combustion engine comprising
- at least one C1-C6 alkyl alcohol;
- and
- 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.
