MUMBAI, India, Aug. 17 -- Intellectual Property India has published a patent application (202617083124 A) filed by Basf Se on July 06, 2026, for Integrated Process For Simultaneously Preparing Alkali Metal Methoxides.
Inventors include Weissker, Wolf-Steffen; Goetz, Manuel Manfred; Hofen, Kai; and Friedrich, Holger.
The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: In a first aspect, the present invention relates to an integrated process for simultaneously preparing n mixtures P(i) comprising alkali metal methoxide and methanol, comprising preparing one or more alkali metal methoxides in n reactive distillation columns K(i) under reactive distillation conditions from n streams H(i) and n streams G(i) comprising methanol, thereby obtaining n top streams W(i) comprising methanol and water; and obtaining n bottoms streams P(i) comprising alkali metal methoxide A(i)OMe and methanol; wherein at least a first stream W(1) and a second stream W(2) are at least partially fed into the rectification column D in that at least a part of the stream W(1) is fed into the lower part of the rectification column D at a position 1(1); and at least a part of the stream W(2) is fed into the lower part of the rectification column D at a position I(2), wherein the position l(2) is located below the position 1(1) and wherein between the positions 1(1) and l(2), the rectification column D is equipped with internals. A second aspect of the invention relates to a chemical production unit for carrying out the process according to the first aspect; and a third aspect of the invention is directed to the use of a chemical production unit according to the second aspect or of a process according to the first aspect for simultaneously producing n mixtures P(i) comprising alkali metal methoxide and methanol.
