  The present invention generally relates to compositions comprising 1-chloro-3,3,3-trifluoropropene. More particularly, the present invention provides an azeotrope-like composition comprising 1-chloro-3,3,3-trifluoropropene and uses thereof.

  Fluorocarbon-based fluids such as chlorofluorocarbon (CFC) or hydrochlorofluorocarbon (HCFC) have desirable properties in industrial refrigerants, blowing agents, heat transfer media, solvents, gaseous dielectrics, and other applications. For these applications, single component fluids, or azeotrope-like mixtures, i.e. those that are not substantially fractionated by boiling and evaporation, are particularly desirable.

  Unfortunately, suspicious environmental problems such as global warming and ozone depletion are due to the use of some of these fluids, which currently limit their use. Hydrofluoroolefins (HFO) have been proposed as a possible alternative to such CFCs, HCFCs, and HFCs. However, locating new environmentally friendly non-fractionable mixtures containing HFO is difficult due to the fact that azeotrope formation cannot be easily predicted. Therefore, there is an ongoing search in the industry for new HFO-based mixtures that are acceptable and environmentally friendly alternatives to CFCs, HCFCs, and HFCs. The present invention satisfies these needs among others.

The composition of the vapor formed by boiling or evaporation of the azeotropic mixture is the same or substantially the same as the composition of the original liquid. Thus, the concentration of components in the liquid and vapor phases of an azeotrope-like composition changes minimally, if any, as the composition is boiled or otherwise evaporated. On the other hand, when the non-azeotropic mixture is boiled or evaporated, the component concentration in the liquid phase changes to a considerable extent.

In another aspect of the present invention, a blowing agent is provided comprising at least one azeotrope-like mixture as described herein. Polymer foams are generally of two general types: thermoplastic foams and thermoset foams.

  Thermoplastic foams are generally described in Throne, Thermoplastic Foams, 1996, Sherwood Publishers, Hinkley, Ohio or Klempner and Sendijarevic, Polymeric Foams and Foam Technology, 2nd edition 2004, Hander Gardner Publications, Inc., Cincinnati, OH. Manufactured by any method known in the art. For example, an extruded thermoplastic foam allows a solution of a blowing agent in a molten polymer that is formed in an extruder under pressure to pass through an orifice at ambient temperature or pressure, or possibly under reduced pressure to help the foam expand. It can be produced by an extrusion process that extrudes onto a moving belt. The blowing agent evaporates and causes the polymer to expand. The polymer is simultaneously expanded and cooled under conditions that give it sufficient strength to maintain dimensional stability at the time corresponding to maximum expansion. Polymers used to make extruded thermoplastic foams include, but are not limited to, polystyrene, polyethylene (HDPE, LDPE, and LLDPE), polypropylene, polyethylene terephthalate, ethylene vinyl acetate, and mixtures thereof. In some cases, several additives including (but not limited to) nucleating agents (eg talc), flame retardants, colorants, processing aids (eg wax), crosslinking agents, permeability modifiers, etc. Is added to the molten polymer solution to optimize foam processing and properties. Further process steps such as irradiation to increase cross-linking, surface film lamination to improve foam skin quality, trimming and design to achieve foam dimension requirements, and other processes. It can also be included during the manufacturing process.

  In general, the blowing agent can include a wide range of amounts of the azeotrope-like composition of the present invention. However, it is generally preferred that the blowing agent comprises at least about 15% by weight blowing agent.

In general, the amount of blowing agent present in the blended mixture is determined by the desired foam density of the final foam product and the process pressure and solubility limits. For example, the proportion (parts by weight) of blowing agent may be within the range of about 1 to about 45 parts, more preferably about 4 to about 30 parts blowing agent per 100 parts by weight polymer. Blowing agents include chlorofluorocarbons such as trichlorofluoromethane (CFC-11), dichlorodifluoromethane (CFC-12), 1,1-dichloro-1-fluoroethane (CFC-11) mixed with an azeotrope-like composition ( HCFC-141b), hydrochlorofluorocarbons such as 1-chloro-1,1-difluoroethane (HCFC-142b), chlorodifluoromethane (HCFC-22), 1,1,1,2-tetrafluoroethane (HFC-134a) ) 1,1-difluoroethane (HFC-152a), 1,1,1,3,3-pentafluoropropane (HFC-245fa), and 1,1,1,3,3-pentafluorobutane (HFC-365mfc) ) Hydrofluorocarbons such as propane, butane, isobutane, cyclopentane, carbon dioxide, chlorinated carbonization Element may be alcohols, ethers, ketones, and additional components, such as mixtures thereof.
