Process for the reductive amination and selective hydrogenation of substrates containing a selected halogen

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. ... Taminco

Improved process for the reductive amination of halogen-containing substrates

Disclosed is a process for performing a reductive amination 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, pt, rh, ir, and ru, and in absence of any catalytic amount of any second metal from the list consisting of ag, ni, co, sn, bi, cu, au, and combinations thereof. 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 active agrochemical compounds and microbicides of the methoximinophenylglyoxylic ester series.. ... Taminco

Stabilized choline solutions and methods for preparing the same

A method for the stabilization of an aqueous choline hydroxide solution includes, optionally adding a first stabilizer of a dithionite salt and/or a dialkylhydroxylamine to an aqueous solution containing reactants that will produce an aqueous choline hydroxide solution; and after the aqueous choline hydroxide solution is formed, adding a second stabilizer which comprises a dialkylhydroxylamine to the aqueous choline hydroxide solution. The stabilized choline hydroxide solution may include choline hydroxide, water, and a dialkylhydroxylamine and optionally a dithionite salt as a stabilizer present in an amount of from about 50 ppm to less than about 5000 ppm by weight relative to the total weight of the stabilized choline hydroxide solution.. ... Taminco

Process for the reductive amination of halogen-containing substrates

Disclosed is a process for performing a reductive amination of a first functional group in an organic feed substrate, which feed substrate comprises at least one further functional group containing a halogen atom, in the presence of hydrogen, a nitrogen-containing compound, and a catalyst, wherein the presence of the nitrogen-containing compound, expressed in a molar ratio relative to the first functional group in the organic feed substrate, at least during the reaction as long as the conversion of the organic feed substrate has not yet reached 80%, is maintained below a level of 1.3. Further disclosed is a composition of the invention comprising at least 98.0% wt of 2-chloro-benzyl-dimethylamine, at most 0.60% wt of the meso-o-cl-bdma dimer and at least 1 ppm wt of the (+/−)-o-cl-bdma dimer and any use therefor.. ...
