Abstract:
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.
Abstract:
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.
Abstract:
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.
Abstract:
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.
Abstract:
The present invention is a composition and cleaning method for use in semiconductor processes wherein the compositions comprises at least one amidoxime compound.
Abstract:
Complexes of ibuprofen and copper and/or zinc were solubilized in ammoniacal solution providing preservative solutions that fully penetrate wood. With loss of the ammonia from the wood, the complexes were stably retained in the wood providing a long lasting preservative.
Abstract:
The present invention pertains to the field of clay compositions, and to tick- or insect-repellent compositions containing clay, particularly to tick- or insect-repellant formulations comprising dihydronepetalactone, a nepetalactam, a dihydronepetalactam and/or their respective derivatives and clay that provide sustained release to improve utilization of the active ingredient and require less-frequent renewal.
Abstract:
Disclosed is a process for preparing dihydronepetalactone by way of a nepetalic acid intermediate to yield a stereospecific product, and compositions and articles made from the product.
Abstract:
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.
Abstract:
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 optimize 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.
