This application relates to efficient and economical synthetic chemical processes for the preparation of pesticidal thioethers. Further, the present application relates to certain novel compounds useful in the preparation of pesticidal thioethers. Specifically, this application relates to a process for the preparation of 3-chloro-1H-pyrazol-4-amine and salts thereof. More particularly, this application relates to a process for the preparation of 3-chloro-1H-pyrazol-4-amine and salts thereof by halogenating and reducing 4-nitropyrazole.

Processes for the preparation of pesticide compounds

Particulate LMFP cathode materials having high manganese contents and small amounts of dopant metals are disclosed. These cathode materials are made by milling a mixture of precursor materials in a wet or dry milling process. Preferably, off-stoichiometric amounts of starting materials are used to make the cathode materials. Unlike other high manganese LMFP materials, these cathode materials provide high specific capacities, very good cycle life and high energies even at high discharge rates.

LMFP cathode materials with improved electrochemical performance

The instant invention provides a process for separating one or more aliphatic diamines from reductive amination reaction solvents and impurities, and aliphatic diamines obtained via such a process. The process for separating one or more aliphatic diamines from reductive amination reaction solvents and impurities according to the instant invention comprises the steps of: (1) feeding one or more cycloaliphatic cyanoaldehydes, hydrogen, ammonia, and optionally one or more solvents into a continuous reductive amination reactor system; (2) contacting said one or more cycloaliphatic cyanoaldehydes, hydrogen, and ammonia with each other in the presence of one or more heterogeneous metal based catalyst systems at a temperature in the range of from 80&#xb0; C. to about 160&#xb0; C. and a pressure in the range of from 700 to 3500 psig; (3) thereby forming a product mixture comprising one or more cycloaliphatic diamines, optionally one or more bicyclic by-products, optionally one or more cycloaliphatic aminonitriles, optionally one or more cycloaliphatic aminoalcohols, optionally one or more oligomeric by-products, ammonia, water, hydrogen, and optionally one or more solvents; (4) removing said product mixture from the reactor system; (5) removing at least a portion of said ammonia, said hydrogen, or mixture thereof from said product mixture via distillation; (6) removing at least a portion of said water and said one or more optional solvents via distillation; (7) removing at least a portion of one or more optional bicyclic by-products via distillation; (8) removing one or more optional cycloaliphatic aminonitriles, one or more optional cycloaliphatic aminoalcohols, one or more optional oligomeric by-products via distillation; and (9) thereby separating said one or more cycloaliphatic diamines from said product mixture.

A process for conversion of aliphatic bicyclic amines to aliphatic diamines including contacting one or more bicyclic amines selected from the group consisting of 3-azabicyclo[3.3.1]nonane and azabicyclo[3.3.1]non-2-ene with ammonia and hydrogen, and alcohols in the presence of heterogeneous metal based catalyst systems, a metal selected from the group consisting of Co, Ni, Ru, Fe, Cu, Re, Pd, and their oxides at a temperature from 140&#xb0; C. to 200&#xb0; C. and a pressure from 1540 to 1735 psig for at least one hour reactor systems; forming a product mixture comprising aliphatic diamine(s), bicyclic amine(s), ammonia, hydrogen, and alcohol(s); removing said product mixture from the reactor system; removing at least some of the ammonia, hydrogen, water, alcohols, bicyclic amines from said product mixture; thereby separating the aliphatic diamines from said product mixture.

Process for the conversion of aliphatic cyclic amines to aliphatic diamines

A process for reductive amination of aliphatic cyanoaldehydes to aliphatic diamines comprising (1) providing a mixture of 1,3-cyanocyclohexane carboxaldehyde and/or 1,4-cyanocyclohexane carboxaldehyde; (2) contacting said mixture with a metal carbonate based solid bed or a weak base anion exchange resin bed at a temperature from 15 to 40 &#xb0; C. for a period of at least 1 minute; (3) thereby treating said mixture, wherein said treated mixture has a pH in the range of 6 to 9; (4) feeding said treated mixture, hydrogen, and ammonia into a continuous reductive amination reactor system; (6) contacting said treated mixture, hydrogen, and ammonia with each other in the presence of one or more heterogeneous metal based catalyst systems at a temperature from 80 &#xb0; C. to 160 &#xb0; C. and a pressure from 700 to 3500 psig; (7) thereby producing one or more cycloaliphatic diamines is provided.
