Patent number: 10252979Abstract: Disclosed is a process for performing a chemical reaction selected from reductive amination and hydrogenation of a first functional group in an organic feed substrate, which feed substrate comprises at least one further functional group containing a halogen atom, wherein the halogen atom is selected from the list consisting of chlorine, bromine, iodine, and combinations thereof, in the presence of hydrogen and a heterogeneous catalyst comprising at least one metal from the list of Pd, Rh, and Ru, together with at least a second metal from the list consisting of Ag, Ni, Co, Sn, Cu and Au. The process is preferably applied for the reductive amination of 2-chloro-benzaldehyde to form 2-chloro-benzyldimethylamine, as an intermediate in the production of agrochemically active compounds and microbiocides of the methoximinophenylglyoxylic ester series.Type: GrantFiled: August 16, 2017Date of Patent: April 9, 2019Assignee: Taminco BVBAInventors: Kristof Moonen, Bart Vandeputte, Daan Scheldeman, Kim Dumoleijn

Patent number: 9527799Abstract: Disclosed is a process for the production of choline hydroxide includes reacting at a temperature above 30.0° C. ethylene oxide, trimethylamine, and water in the presence of an aqueous medium in such amounts as to form a diluted choline hydroxide solution having a choline hydroxide concentration of less than 40 wt % and removing at least a portion of the aqueous medium from the diluted choline hydroxide solution to form a concentrated aqueous choline hydroxide solution having a choline hydroxide concentration which is at least 1.05 times the choline hydroxide concentration of the diluted choline hydroxide solution. The process allows for large scale, continuous production of concentrated aqueous choline hydroxide solutions of good quality under economically advantaged consumption factors for ethylene oxide.Type: GrantFiled: April 10, 2014Date of Patent: December 27, 2016Assignee: TamincoInventors: Kristof Moonen, Dieter Ulrichts, Daan Scheldeman

Patent number: 9216944Abstract: A continuous process for the production of choline hydroxide includes reacting ethylene oxide, trimethylamine, and water in a reaction zone to form a reaction mixture and extracting heat from the reaction mixture. Subsequently, phase separation of the reaction mixture is induced to obtain a choline hydroxide phase and an organic liquid phase comprising trimethylamine. A choline hydroxide solution (e.g., at a concentration of about 40% to 50% by weight, based on total weight of the choline hydroxide solution) is obtained from the choline hydroxide phase.Type: GrantFiled: December 29, 2011Date of Patent: December 22, 2015Assignee: TAMINCOInventors: Kristof Moonen, Dieter Ulrichts, Daan Scheldeman

Patent number: 8916214Abstract: A process is described for obtaining free flowable, carrier free powders from aqueous solutions of deliquescent quaternary ammonium compounds in a two step process, comprising a drying and a powder mixing step. The excellent free-flowing and stability characteristics of the final product could only be obtained when among possible other additives at least one univalent metal fatty acid salt is added to the liquid phase in the drying step and at least one multivalent metal fatty acid salt in the powder mixing step. A surprising synergy was observed between these additives when applied as described in the present invention.Type: GrantFiled: December 24, 2009Date of Patent: December 23, 2014Assignee: Taminco N.V.Inventors: Kristof Moonen, Daan Scheldeman
