    摘要： The present disclosure relates to a single-pot multi step process for the preparation of a shape controlled pro-catalyst. The process comprises the steps of: i. reacting magnesium metal and at least one alkanol to obtain spheroidal magnesium alkoxide; ii. treating the spheroidal magnesium alkoxide with at least one transition metal tetrahalide, at least one organic modifier, and optionally, at least one in-organic modifier in the presence of at least one solvent to obtain a reaction mixture; iii. cooling, settling the reaction mixture and decanting the supernatant; iv. adding at least one transition metal tetrahalide, at least one solvent and optionally, at least one organic or inorganic modifier; and v. iterating steps (iii) and (iv) to obtain the shape controlled pro-catalyst.

    摘要： The purpose of the present invention is to provide a spherical or ellipsoidal magnesium alcoholate having a narrow particle size distribution even when the particle size is small. The present invention provides a method for producing a magnesium alcoholate by adding in a portionwise manner to a reaction system and reacting, metallic magnesium, an alcohol, and at least one of a halogen or a halogen atom-containing compound in the reaction system under alcohol reflux, which is a method for producing a magnesium alcoholate characterized in that a mixture of metallic magnesium, an alcohol, and at least one of a halogen or a halogen atom-containing compound is added to the reaction system at each portionwise addition.

    摘要： The invention relates to a method for the distillative processing of a methanol/water mixture, wherein a methanol/water mixture is added to a distillation column (1), a vapor stream substantially comprising methanol is removed at the head of the distillation column (1), and a bottom stream substantially comprising water is withdrawn at the base of the distillation column (1), at least part of the vapor stream substantially comprising methanol is condensed and the condensed vapor stream is added as heating vapor to an evaporator (11), in which at least part of the methanol/water mixture to be separated is vaporized. The invention further relates to a method for producing alkali methylates in a reaction column (31), wherein methanol and alkaline lye are added to the reaction column (31). At the lower end of the reaction column (31), alkali methylate dissolved in methanol is withdrawn, and a methanol/water mixture is withdrawn at the upper end of the reaction column (31) and the methanol/water mixture is processed by way of the method for distillative processing.
