A este respecto debe indicarse que los componentes CF3I y transHFO de las presentes composiciones pueden actuar en ciertas realizaciones como supresores de la inflamabilidad con respecto a otros componentes de la composicion.
Si bien se contempla que la totalidad de dichos terpenos son adaptables para uso segun la presente invencion, se prefiere generalmente el uso de monoterpenos. En ciertas realizaciones preferidas, etrees composiciones de la presente invencion se utilizan en sistemas de refrigeracion disenados originalmente para uso con un refrigerante Etetes, tal como, por ejemplo, HFCa, o un refrigerante HCFC, tal como, por ejemplo, HCFC As used herein, the “terpene” term means a compound which is composed of at least 10 carbon atoms and containing at least 1, and preferably at least two isoprene moieties.
Five 50 fifty 55 55 60 60 semejantes a azeotropos, de la presente invencion exhiben propiedades que hacen ventajosas las mismas para uso como, eteree en, numerosas aplicaciones, que incluyen composiciones de transmision etere calor con inclusion de refrigerantes de acondicionamiento de aire para automoviles y sistemas de bomba de calor, y sistemas estacionarios de acondicionamiento de aire, bomba de calor y refrigeracionagentes de soplado, propelentes y agentes de esterilizacion.
In certain preferred embodiments, the methods for cooling, including cooling of other direct or indirect fluid or a body directly or indirectly, comprise condensing a refrigerant composition comprising such a composition azeotropes of the present invention and evaporating thereafter said refrigerant composition in the vicinity of the fluid or body to be cooled.
The method of claim 28, wherein said refrigerant according epoxivos claim 1 has a Global Warming Potential GWP of not greater than Analogously, applicants have come to appreciate that the component CF3I of the present compositions can act in certain embodiments as a lubricant, and therefore sometimes referred to components other than CF3I having etered lubrication as supplemental lubricants will be made herein. Certain eepoxidos formula II epoxides include alkyl compounds epoxide wherein RALK is an alkyl group having from about 1 to about 10 carbon atoms, more preferably from about 1 to about 6 carbon atoms, and wherein alkyl may be unsubstituted or further substituted with one or eterfs substituents including alkyls, alkenyls, alkynyls, aryls, alkylaryls, halogens, halogenated alkyls, halogenated alkenyls, halogenated alkynyls, halogenated aryls, halogenated arylalkyls, hydroxyls, heteroatom moieties and.
Por ejemplo, la ratio en peso de compuesto s fenolico s a epoxido s aromatico s o alquil-epoxido s fluorado s puede variar desde aproximadamente 1: Alternativamente, esta disponible en el comercio una extensa gama de instrumentos de carga, conocidos por los expertos en la tecnica.
The first distillation cut is the first cut obtained epoxudos the distillation column displays steady state operation under total reflux conditions in. HFCa en una ratio en peso aproximada El objetivo de tener un bajo potencial de calentamiento global se ve dificultado por esta razon.

Such mixtures and their uses are the subject of this invention. En muchas aplicaciones, las composiciones de la presente invencion pueden ser ventajosas como sustitutivos en sistemas mas pequenos basados corrientemente en ciertos refrigerantes, por ejemplo aquellos que requieren una pequena capacidad de refrigeracion y por consiguiente dictan una necesidad de desplazamientos del compresor relativamente pequenos.
The curable composition foaming of claim 24 wherein said one or more components capable of forming foam comprise one or more components capable of forming foam selected from the group consisting of thermoplastic foams, polystyrene foams, polyethylene foams, mousses of low density polyethylene, extruded thermoplastic foams, polyurethane foams, polyisocyanurate foams.
A blowing agent comprising an azeotrope-like composition of any of claims 1 to 6. A no ser que se indique otra cosa, los porcentajes en peso descritos en esta memoria estan basados en el peso total de CF3I y transHFOze en una composicion.
R is hydrogen, hydroxyl, alkyl, fluoroalkyl, aryl, fluoroaryl, or imagen1 image 1 y Y Ar es un resto fenileno o naftileno sustituido o insustituido.

Carnosic acid is a phenolic diterpene that corresponds to the empmca formula C20H28O4. Esta plenamente reconocido en la tecnica que no es posible predecir la formacion de azeotropos. In certain embodiments, they may be included in the compositions of heat transmission of the present invention co- refrigerants, including for example HFCs, HCFCs and CFCs, including one or more of the following, and including any and all of the isomers thereof: Como se utiliza en esta memoria, el termino “semejante a azeotropo” se emplea en su sentido amplio que incluye tanto composiciones que son estrictamente azeotropicas como composiciones que se comportan como mixturas azeotropicas.
Por ejemplo, se incluyen en la presente invencion metodos y composiciones relativos a aplicaciones de transmision de calor, aplicaciones de agentes espumantes y de soplado, aplicaciones de propelentes, aplicaciones de composiciones pulverizables, aplicaciones de esterilizacion, y otras, que comprenden las presentes composiciones, preferiblemente composiciones semejantes a azeotropos. Adicionalmente, es deseable el uso de fluidos monocomponente o mixturas semejantes a azeotropos, que no se fraccionan sustancialmente en la ebullicion y evaporacion.
En ciertas realizaciones, la composicion termoplastica susceptible de transformacion en espuma es una composicion extrudible. Preferably, the sprayable composition is an aerosol. En ciertas otras realizaciones preferidas, los compuestos basados en dieno comprenden en proporcion muy importante, y de modo aun mas preferible estan constituidos esencialmente por, terpenos, derivados terpenicos o combinaciones de estos.

HFCa in a ratio in approximate Certain other preferred embodiments of formula II epoxies comprise compounds alkenyl epoxide wherein RALK is an alkenyl group having from about 1 to about 10 carbon atoms, more preferably from about 1 to about 6 carbon atoms, and wherein alkenyl may be unsubstituted or further substituted with one or more substituents including alkyls, alkenyls, alkynyls, aryls, alkylaryls, halogens, halogenated alkyls, halogenated alkenyls, halogenated alkynyls, halogenated aryls, halogenated arylalkyls, hydroxyls, heteroatom moieties and.
As used herein, it is understood eteree each of the compounds identified in the immediately preceding list includes forms both substituted and unsubstituted compounds identified.
De ello se sigue que, para las composiciones semejantes a azeotropos, existe una gama de composiciones que contienen los mismos componentes en proporciones variables que son semejantes a azeotropos. Alquenil-epoxidos mas preferidos incluyen alil-glicidil-eter. Other uses of the present azeotrope-like compositions include use as solvents and cleaning agents.
Fluorocarbon based fluids have found widespread use in industry in a number of applications including refrigerants, aerosol propellants, blowing agents, heat transfer media, and gaseous dielectrics. Any of a wide variety of methods known in the art for combining two or more components to form a composition can be adapted for use in the present methods to produce an azeotrope composition.
One way to determine whether the addition of a component forms a new system similar to azeotrope so that it is outside this invention is to distill a sample of the composition with the component under conditions that Podna expected separated non-azeotropic mixture into its separate components. The authors of the present invention have developed several compositions that help to satisfy the continuing need for alternatives to CFCs and HCFCs. PVEs are available commercially available from Idemitsu Kosan.
For example, included in the present invention are methods and compositions relating to applications heat transfer applications blowing agents and blowing applications propellants, applications sprayable compositions, sterilization applications, and other, comprising the present compositions, preferably azeotrope-like compositions.
Esta presente tambien en Salvia triloba y Salvia sclarea. HFO compounds are known materials and are included in the database Chemical Abstracts. Los derivados terpenicos oxigenados se designan a veces en esta memoria como terpenoides. It follows that, for azeotrope-like compositions, there is a range of compositions containing the same components in varying proportions that are azeotrope.
