摘要:
Pure methyl-t-butyl ether is used as a cosolvent for hydrous ethanol in gasoline fuel mixtures. The ether solubilizes grain alcohol in all proportions in low aromatics content gasolines.
摘要:
Hydrocarbon fuels heavier than gasoline may be extended by addition thereto of ether or ester fuel extenders, soluble in the hydrocarbon fuel, having a molecular weight of about 65-200 and characterized by the presence of at least one methoxy group or ethoxy group. The product is a single-phase mixture which is free of methanol or ethanol.
摘要:
Gasoline and aqueous alcohol, such as 95 w % ethanol, are mixed to form wet two-phase gasahol (including a hydrocarbon phase and a water phase); and the water-phase is separated and reacted with a ketal, acetal, or orthoester to form a dry composition which is blended back into the gasoline-phase to form a dry gasahol.
摘要:
Hydrocarbon fuels including gasoline and fuels heavier than gasoline may be extended by addition thereto of ether-alcohol extenders, soluble in the hydrocarbon fuel, prepared by etherifying an oxy-alcohol mixture. The product is a single-phase mixture which possesses improved water tolerance.
摘要:
Conductivity of a low flash point diesel fuel containing diluent naphtha is increased by addition thereto of an amyl alcohol, typically a fusel oil.
摘要:
A fuel composition comprising a mixture of hydrocarbons boiling in the middle distillate boiling range and an effective stabilizing amount of a alpha, omega diamino poly(oxypropylene) poly(oxyethylene) poly(oxypropylene) represented by the formula: ##STR1## wherein x and z each has an approximate value ranging from 1 to 3 such that the sum of x plus z has an average value ranging from 3 to 4, and y has an approximate value ranging from 10 to 16.
摘要:
A novel fuel composition contains ethanol or gasohol plus, as a wear-inhibiting additive, a quaternary ammonium reaction product of an amine ##STR1## typically bis(2-hydroxyethyl)cocoamine and a phosphate, or phosphonic acid, typically dilauryl phosphate.
摘要:
A novel fuel composition contains ethanol or gasohol plus, as a wear-inhibiting additive, a quaternary ammonium reaction product of dilauryl phosphate and a t-alkyl monoamide of iminodiacetic acid.
