The present invention relates to a process for the removal of naphthenic acids from crude oils and crude oil distillates by use of supported basic ionic liquids.

Process for removing naphthenic acids from crude oil and crude oil distillates

The invention relates to a method of inhibiting corrosion by corrosive fluids, and more specifically to inhibiting corrosion of a metallic surface. The method comprising adding to the corrosive fluid a specifically selected ionic liquid which is added in an amount, based on the total weight of the corrosive fluid, effective to mitigate or alleviate corrosion.

Corrosion inhibition

This invention relates to solvents for extracting Cto Ccarboxylic acids from aqueous streams. More specifically, the extraction solvents include one or more salts composed of a tetraalkylphosphonium cation and a phosphinate anion. The extraction solvents may further include one or more co-solvents as an enhancer. The co-solvents may be selected from higher carboxylic acids, ethers, esters, ketones, aromatic hydrocarbons, chlorinated hydrocarbons, and nitriles. The extraction solvents are useful for extracting aqueous mixtures containing one or more lower carboxylic acids, such as monocarboxylic acids and organofluorine carboxylic acids.

This invention relates to solvents for extracting Cto Ccarboxylic acids from aqueous streams. More specifically, the extraction solvents include one or more salts composed of a phosphonium cation and an arylcarboxylate anion. The extraction solvents may further include one or more non-ionic liquid organic solvents as an enhancer. The extraction solvents are useful for extracting aqueous mixtures containing one or more lower carboxylic acids, such as monocarboxylic acids, alkoxycarboxylic acids, and halogen-containing carboxylic acids.

Disclosed are heterogeneous processes (i) for the hydrogenation of a compound containing at least one unsaturated carbon-carbon bond, and (ii) for the hydro-dehalogenation of a compound containing at least one C&#x2014;Cl, C&#x2014;Br or C&#x2014;I bond. The processes comprise reacting said compound with a hydrogenating agent and a heterogeneous hydrogenation catalyst in the presence of an ionic liquid.

Hydrogenation processes

Hydrogenation process

According to one aspect of the invention, there is provided the use of an organic ionic liquid in a zeolite-catalysed process, for example an acylation, alkylation, isomerisation or hydrocracking process in which zeolites act as catalysts or catalyst precursors, especially Friedel-Crafts alkylation and acylation procedures.
