A process is described for the recovery of substantially pure ethyl acetate from a feedstock including ethyl acetate, ethanol and water. The process includes supplying the feedstock to a first distillation zone maintained under first distillation conditions effective for distilling from the feedstock a first distillate including ethyl acetate, ethanol, and less than about 10 mol % water. The first distillate is recovered from the first distillation zone and is supplied to a second distillation z...

A process for hydrogenation of glycerol in which a feed comprising glycerol is contacted with a stream of a hydrogen-containing gas and subjected to hydrogenation in the vapour phase in the presence of a catalyst at a temperature of from about 160.degree. C. to about 260.degree. C., a pressure of from about 10 to about 30 bar, a hydrogen to glycerol ratio of from 400:1 to about 600:1 and a residence time of from about 0.01 to about 2.5 secs.

The present invention provides a process for dosing a fuel with a fuel additive comprising (i) passing the fuel from a fuel container through a dosing apparatus (ii) dosing the fuel with additive in an amount based on the fuel passing through the dosing apparatus and independently of the concentration of the additive in the fuel (iii) returning a portion of the fuel to the container.

The present invention relates to a process for preparing a pharmaceutical starting compound compound by hydrolyzing a compound of the general formula (II): Wherein R.sup.1 is protected carboxy, R.sup.2 is lower alkoxy or higher alkoxy, A.sup.1 is an aromatic bivalent group, heterocyclic bivalent group or cyclo (lower) alkane bivalent group, and A.sup.2 is an aromatic bivalent group, heterocyclic bivalent group or cyclo (lower) alkane bivalent group, with aqueous potassium hydroxide and by treati...

The present invention provides an improved process for the preparation of .alpha.-polymorphic eletriptan hydrobromide.

The present invention provides an improved process for the preparation of a polymorph of eletriptan hemisulphate.

A process for the preparation of coated polymer particles containing superparamagnetic crystals, said process comprising reacting porous, surface-functionalized, superparamagnetic crystal-containing polymer particles of diameter 0.5 to 1.8 .mu.m with at least one polyisocyanate and at least one diol or at least one epoxide.

A wet granulation process in which a pharmaceutical substance is granulated using a granulating fluid which is a halogenated hydrocarbon which has a normal boiling point below ambient temperature, for example 1,1,1,2-tetraflouroethane, under a pressure sufficient to maintain the halogenated hydrocarbon in a liquid state. A process in which the halogenated hydrocarbon is re-cycled, and suitable equipment for performing the process is also described.

A novel process for the removal of impurities from clavulanic acid using a selective adsorption material, in particular a molecularly imprinted polymer. Novel selective adsorption materials suitable for the process, and a process for the preparation of such selective adsorption materials, are also disclosed.

There is provided a process for the production of a N-benzyl azetidine-2-carboxylic acid alkylphenyl, or alkyl, ester which process comprises the reaction of an optionally substituted alkylphenyl, or an optionally substituted alkyl, 2-bromo-4-chlorobutyrate with an optionally substituted benzylamine, which process may be used as part of an overall process for the production of azetidine-2-carboxylic acid.
