    摘要： Reaction products of polymeric alkyl phenol formaldehyde resins are useful as additives to inhibit or prevent the deposition or precipitation of asphaltenes in hydrocarbon fluids, particularly crude oil produced from a subterranean formation. These reaction products are formed by reacting a polymeric alkyl phenol formaldehyde resin with a co-reactant having functional groups including, but not necessarily limited to, amines, esters, silanes, ketones, epoxides, alkoxides, aryloxides, halogens, alkali metals, alkali earth metals, acetamides, non-metal oxides, metal oxides, where the co-reactant optionally has a carbon chain length between 1 and 22 and the reaction is conducted in the presence of at least one of various solvents. In one non-limiting embodiment, the co-reactant is a silicon derivative. The asphaltene inhibitors have utility when injected into a subterranean formation while oil production temporarily halts, a process called “squeezing,” because they are retained to a degree in the formation as the crude oil is produced.

    摘要： Reacting an alkylene carbonate, such as ethylene carbonate, with dimer acid in the presence of a catalyst, such as a tertiary amine catalyst, gives a dimer acid diester having essentially no sulfur, and thus may be added to ultra-low sulfur diesel fuel downstream of a refinery. The diester enhances the lubricity properties of hydrocarbon fuels, increases their service life and fuel efficiency. The manufacturing process time may be decreased significantly compared with a process using ethylene glycol instead of ethylene carbonate, and much less ethylene glycol by-product results.

    摘要： Dithiocarbamic salts made from the reaction products of certain polyamines and epoxides have been found to be useful to clarify water, particularly the oil-in-water emulsions which accompany crude oil production. The water clarification may be accomplished by demulsification or flocculation. The polyamine reaction products themselves are novel and may have the structure ##STR1## where R" is selected from the group consisting of the structure --R--NH.sub.2 and ##STR2## where R is selected from the group consisting of straight, branched or cyclic alkylene moieties; arylene moieties; substituted straight, branched or cyclic alkylene moieties; substituted arylene moieties or mixtures thereof; and where R' is--(CH.sub.2).sub.m --O--R--O--(CH.sub.2).sub.m --where n and m independently range from 1 to 5 and q is 0 or 1. The dithiocarbamic salts made from these polyamines also find use as corrosion inhibitors.
