Methods of measuring hydrogen sulfide concentrations in reservoir fluids

Process for the manufacture of sulphur-containing fertilizer compositions, comprising the steps of: a} providing a slurry of at least one phosphate-based fertilizer material selected from the group consisting of ammonium phosphates, ammonium phosphate based nitrogen-phosphorus-potassium (NPK) compounds, super phosphates and partially acidulated phosphate rocks; b) bringing said slurry into contact with at least one anionic surfactant and elemental sulphur; c) introducing the mixture obtained in step b} into a granulator unit in order to obtain granules of the fertilizer composition, wherein the at least one phosphate-based fertilizer material is present in an amount in the range of at least 50 wt. %, the elemental sulphur is present in an amount in the range of from 1 to 25 wt. % and the anionic surfactant is present in an amount in the range of from 0.001 to 3 wt. % based on the overall weight of the fertilizer composition. The present invention also provides a fertilizer composition.

Sulphur-containing fertilizers and process for the preparation thereof

A process comprising the steps of dissolving a dihydric phenol in a solvent to form a solution A, contacting the solution A with an adsorbent material selected from the group consisting of metal oxides, modified metal oxides, activated carbons, and clays, filtering the adsorbent material to form a solution B, adding an anti-solvent to the solution B to form a solution C, and distilling the solution C, wherein the dihydric phenol is represented by Formula (I): wherein R is a hydrogen atom or an aliphatic functionality having 1 to 6 carbon atoms and n is an integer having a value of 1 to 4.

Process for the purification of dihydric phenols

A process comprising the steps of dissolving a dihydric phenol in a solvent to form a solution A; contacting the solution A with a zeolite; filtering the zeolite to form a solution B; adding an anti-solvent to the solution B to form a solution C; and distilling the solution C; wherein the dihydric phenol is represented by Formula (I): wherein R is a hydrogen atom or an aliphatic functionality having 1 to 6 carbon atoms and n is an integer having a value 1 to 4.

Method of purification of dihydric phenols

A process for the preparation of hydroquinone compounds comprising, reacting an aromatic hydroxy compound with an oxidizing agent in a biphasic solvent system. The reaction is carried out in the presence of a transition metal hydroxy phosphate catalyst to produce the corresponding hydroquinone compound.

Processes for preparing benzoquinones and hydroquinones

A continuous process comprising: contacting a mixture comprising dihydroxy aromatic compound, water and an alkylating agent with a catalyst system in the presence of a flowing carrier gas, to form a mono alkylated dihydroxy aromatic compound, wherein the catalyst system is obtained by the calcination of a catalyst precursor system comprising a metal oxide precursor, a transition metal element and a pore former.

Process for the monoalkylation of dihydroxy aromatic compounds
