摘要:
Disclosed are methods for treating catmint oil. The treated catmint oil can be used for the production of hydrogenated catmint oil, which is enriched in the insect repellent, dihydronepetalactone, and from which formulated products may be prepared.
摘要:
A process for the hydrogenation of a mixture of caryophyllenes by contact with hydrogen in the presence of a supported catalyst. The resulting products are useful for the application to skin.
摘要:
This invention provides a process for producing dihydronepetalactone using mixtures comprising both trans-cis nepetalactone and cis-trans nepetalactone. A reaction mixture comprising trans-cis nepetalactone and cis-trans nepetalactone is first contacted with hydrogen in the presence of at least one hydrogenation catalyst under conditions that optimise the preferential conversion of trans-cis nepetalactone to dihydronepetalactone. Cis-trans nepetalactone is subsequently converted to dihydronepetalactone by contact with hydrogen in the presence of at least one hydrogenation catalyst.

摘要:
Semiconductor processing compositions comprising amidoxime compounds having two or more amidoxime functional groups and their use in semiconductor processing to remove photoresist, polymeric materials, etching residues and copper oxides from semiconductor substrates, particularly substrates comprising copper, low-k dielectric material, titanium nitride, and/or titanium oxynitride.
