摘要:
A high yielding method is described for recovery of catmint oil from catmint plants of the genus Nepeta by improved separation of a catmint oil containing phase from the condensed steam distillate of catmint plants. Catmint oil may be obtained in quantitative yields for use in insect repellent compositions.
摘要:
This invention relates to a temperature adjustment device that executes an absorption cooling or heating cycle in which a lithium halide, typically a lithium bromide, absorbent is used.
摘要:
Disclosed herein are compositions comprising lithium bromide, water, and at least one ionic compound. These compositions are useful as working fluids in absorption cycle systems. The ionic compound additive has been demonstrated to reduce crystallization in such absorption cycle systems.
摘要:
A method for recovering for a material such as an absorbed solute from an ionic liquid is described. In the method, an electric field is applied to the ionic liquid to release the absorbed solute.
摘要:
This invention relates to copper complexes that significantly reduce the decay of wood, cellulose, hemicellulose, and lignin caused by fungi. A process for treating such materials with these copper-containing anti-fungal agents is also disclosed.
摘要:
Dihydronepetalactone, a minor natural constituent of the essential oil of catmints (Nepeta spp.) such as Nepeta cataria, has been identified as an effective insect repellent compound. Synthesis of dihydronepetalactone may be achieved by hydrogenation of nepetalactone, the major constituent of catmint essential oils. This compound, and compositions thereof, which also has fragrance properties, may be used commercially for its insect repellent properties.
摘要:
This invention relates to wood preservatives containing copper complexes and calcium ions, zinc ions or calcium and zinc ions for protection of wood, cellulose, hemicellulose, lignocellulose, cellulosic materials and articles derived from cellulosic materials from decay caused by fungi. The calcium ions, zinc ions, or calcium and zinc ions improve the penetration of copper preservative agent into the interior of a treated material or article.
摘要:
This invention relates to compositions comprising a refrigerant and at least one ionic compound and/or non-ionic absorbent, and also to devices capable of executing an absorption cycle using such compositions as a refrigerant pair. This invention also provides methods and apparatus for cooling using an absorption cycle comprising a refrigerant, and at least one ionic compound and/or non-ionic absorbent as the absorbent. This invention also provides methods and apparatus for heating using an absorption cycle comprising a refrigerant, and at least one ionic compound and/or non-ionic absorbent,
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.
