    摘要： Lubricity additives for hydrocarbon fuels are provided according to formula I: wherein n is 1 or 0; each Q is independently selected from oxygen and sulfur; each R is independently selected from C8-C60 alkenyl groups which are substituted or unsubstituted; and L is a linking group comprising 0-20 carbons which may be substituted or unsubstituted and may optionally comprise catenary heteroatoms. Fuel mixtures comprising a hydrocarbon fuel; and a lubricity additive according to the present disclosure are also provided. Methods of making lubricity additives comprise reacting an alkenyl succinic anhydrides (ASA's) with certain bisamides or bisthioamides.

    摘要： The present disclosure relates to a gas hydrate inhibitor composition comprising an amphiphile having a hydrophobic tail linked to a hydrophilic head group by a linking moiety, the amphiphile having the general formula (1) [R5-L-N(R1)(R2)(R3)]+X−  (1) wherein each of R1 and R2 is independently an alkyl group having from 1 to 5 carbon atoms; or wherein the nitrogen atom and the R1 and R2 groups together form a substituted or unsubstituted heterocyclic group; R3 is present or not as hydrogen or an alkyl group having from 1 to 8 carbon atoms which optionally bears a hydroxy group or a carboxy group in the 2-position; L is a linking moiety comprising an optionally substituted hydrocarbyl group having at least 2 adjacent carbon atoms, at least one heteroatom selected from nitrogen and oxygen, and optionally one or more further heteroatoms; R5 is a hydrocarbyl group having from 6 to 22 carbon atoms; and X− is present as an anion when R3 is present; and a nonionic surfactant which is selected from alkoxylated C8-C18 fatty alcohols, alkoxylated C8-C18 fatty amines, alkoxylated C8-C18 fatty acids and alkoxylated C8-C18 fatty acid amides and a method of using the gas hydrate inhibitor composition.
