An energetic formulation includes graphene oxide functionalized with a molecule containing at least one epoxy group. The graphene oxide may include at least one functional group containing nitrogen between a graphene sheet and the at least one epoxy group. The epoxy group may be sourced from a hydrocarbon compound containing a plurality of epoxy groups. The functionalized graphene oxide may be coated onto ammonium perchlorate. The functionalized graphene oxide is used as a stand-alone energetic material in powder form, mixed as powder in a liquid fuel, or mixed as a powder in a solid fuel.

The present invention relates to a process for preparing cyclic acetals having general formula (I) wherein Y and Y, equal to or different from each other, are selected from H and a group OR, R being a linear or branched alkyl containing from 1 to 8 carbon atoms, comprising at least the following phases: (i) providing a reaction mixture comprising at least one vicinal diol having formula (II) ZCH2-CHOHCH2OH wherein Z is selected from H and a group OR, R being a linear or branched alkyl containing from 1 to 8 carbon atoms, said mixture being substantially free of aldehydes having general formula R.sup.1CHO, wherein R.sup.1 is a linear or branched alkyl containing from 1 to 6 carbon atoms, possibly substituted by an alkoxide group OR111, wherein R.sup.III is an alkyl containing from 1 to 4 carbon atoms; (ii) thermally treating said reaction mixture at a temperature within the range of 100 C.-300 C. in the presence of at least one acid catalyst, obtaining said compound having formula (I). The acetals having formula (I) can be used as fuel components.

A method of controlling wax deposition within a fluid, the method including admixing an additive composition with the fluid, wherein the additive composition includes one or more biosurfactants and one or more additional additives independently selected from (i) a sulfonic acid or salt thereof, (ii) a polymeric wax inhibitor and (iii) an alkoxylated alcohol and/or amine compound.

The present invention discloses polyethyleneamine salts of sulphonyl oleic acid and a 5 hydrocarbon fuel additive composition comprising the same. The said polyethyleneamine salts of sulphonyl oleic acid is made by mixing a sulphonyl oleic acid with at least one polyethyleneamine. Wherein, the sulphonyl oleic acid is selected from at least one of (9Z)-8-sulfo-octadec-9-enoic acid or (9Z)-11-sulfo-octadec-9-enoic acid. The at least one polyethyleneamine is selected from triethylenetetramine (TETA), or diethylenetriamine 0 (DETA), pentamethyldiethylenetriamine, tetraethylenepentamine, 1,4,7-triazacyclononane, 1,1,1-Tris(aminomethyl)ethane, or cyclen. The hydrocarbon fuel additive composition is made of polyethyleneamine salts of sulphonyl oleic acid and a cosolvent system consisting of sulphonyl oleic acid and dioxane. Wherein, the said hydrocarbon fuel additive composition acts as a dual functional additive and synergistically improves the conductivity as well as 5 lubricity of a hydrotreated diesel fuel.
