Abstract
Official abstract text for this publication.
The present disclosure relates to a single-pot process for the preparation of a shape controlled pro-catalyst. The process comprises the steps of i. reacting at least one alkanol with magnesium metal using at least one modifier and optionally, at least one solvent resulting in evolution of hydrogen gas, increasing the evolution of the hydrogen gas in a controlled manner by increasing the temperature in a graded manner to 100° C. to obtain a mass, and ii. subjecting the mass to drying to obtain a free flowing procatalyst.
First claim
Opening claim text (preview).
The invention claimed is: 1. A single-pot process for the preparation of a shape controlled pro-catalyst; said process comprising the following steps: a. reacting at least one alkanol with magnesium metal using at least one modifier and at least one solvent resulting in evolution of hydrogen gas; increasing the evolution of hydrogen gas in a controlled manner by increasing the temperature in a graded manner to 100° C. to obtain a mass, and b. subjecting the mass to drying to obtain a free flowing pro-catalyst. 2. The process as claimed in claim 1 , wherein the alkanol is selected from the group consisting of methanol, ethanol, propanol, isopropanol, butane, isobutanol and t-butanol. 3. The process as claimed in claim 1 , wherein the modifier is selected from the group consisting of organic modifier and inorganic modifier. 4. The process as claimed in claim 3 , wherein organic modifier is at least one selected from the group consisting of ethyl benzoate, di-isobutyl phthalate and 9, 9-bis (methoxymethyl) fluorine. 5. The process as claimed in claim 3 , wherein the inorganic modifier is selected from the group consisting of titanium tetrachloride (TiCl 4 ), vanadium tetrachloride (VCl 4 ), silicon tetrachloride (SiCl 4 ), zirconium tetrachloride (ZrCl 4 ) and hafnium tetrachloride (HfCl 4 ). 6. The process as claimed in claim 1 , wherein the solvent is selected from the group consisting of aliphatic and aromatic solvent. 7. The process as claimed in claim 1 , wherein the shape controlled pro-catalyst has a particle size in the range of 10 to 50 μ.
