The present invention relates to blowing agent compositions of carbon dioxide and at least one hydrochlorofluoroolefin (HCFO). The HCFOs can include, but are not limited to, 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd), 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf) and mixtures thereof. The blowing agent compositions are useful in the production of low density insulating foams with improved k-factor made from thermoplastic resins. The blowing agent compositions may also optionally include one or more hydrofluoroolefins (HFOs).

Blowing agent compositions of carbon dioxide and hydrochlorofluoroolefins

The present invention relates to non-flammable compositions comprising chlorotrifluoropropene with reduced risk of flammability which are useful as refrigerants, heat transfer fluids, solvents, cleaners, blowing agents, aerosols, extraction fluids, and the like.

Non-flammable compositions of chloro-trifluoropropene

The present invention relates to solvent/cleaner and heat transfer fluid compositions comprising at least one hydrochlorofluoroolefin (HCFO), 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd), particularly the trans-isomer. The HCFO of the present invention can be used in combination with co-agents including, hydrofluorocarbons (HFCs), hydrofluoroolefins (HFOs), hydrocarbons, ethers including hydrofluoroethers (HFEs), esters, ketones, alcohols, 1,2-transdichloroethylene and mixtures thereof.

Compositions of hydrochlorofluoroolefins

The present invention relates to sorbants such as metal-organic frameworks (MOFs), covalent organic frameworks (COFs), porous aromatic frameworks (PAFs) or porous polymer networks (PPNs) for separations of gases or liquids, gas storage, cooling, and heating applications, including, but not limited to, adsorption chillers.

Adsorption systems using metal-organic frameworks

This invention relates to the use of chloro-trifluoropropenes as refrigerants in negative-pressure liquid chillers and methods of replacing an existing refrigerant in a chiller with chloro-trifluoropropenes. The chloro-trifluoropropenes, particularly 1-chloro-3,3,3-trifluoropropene, have high efficiency and unexpectedly high capacity in liquid chiller applications and are useful as more environmentally sustainable refrigerants for such applications, including the replacement of R-123 and R-11.

Use of R-1233 in liquid chillers

The present invention relates to formulated refrigerant systems of 1-chloro-3,3,3-trifluoropropene (R-1233zd) that are sufficiently thermally and chemically stable such that they can be effectively used sans additional stabilizers. The formulations of the present invention are particularly useful compositions for refrigeration, heat transfer and foam blowing.

Stable formulated systems with chloro-3,3,3-trifluoropropene

A blowing agent for thermosetting foams is disclosed. The blowing agent is a hydrofluoroolefin (HCFO), preferably HFCO-1234yf in combination with a hydrochlorofluoroolefin (HCFO) preferably one selected from HCFO-1233zd, HCFO-1223, HCFO-1233xf and mixtures thereof. The blowing agent is effective as a blowing agent in the manufacture of thermosetting foams.

Blowing agent composition of hydrochlorofluoroolefin and hydrofluoroolefin

The present invention provides methods for selecting refrigerant and lubricant combinations for use in heat transfer cycle systems and provides methods for operating said heat transfer systems. More particularly, the invention provides methods to select lubricant and refrigerant combinations for a heat transfer cycle system wherein at the lower temperatures of the heat transfer cycle the refrigerant and lubricant are miscible and at the upper temperatures of the heat transfer cycle the refrigerant and lubricant are phase separated and such that the density phase inversion temperature of the combination is below the upper operating temperature of the heat transfer cycle.

Method of selecting refrigerant-lubricant combinations

The present invention relates to blowing agent compositions comprising tetrafluoropropene (HFO) and at least one co-blowing agent selected from carbon dioxide, water, alkanes and an alcohol used in the preparation of foamable thermoplastic compositions having low density. The HFOs include, but are not limited too, cis- and/or trans-1,3,3,3-tetrafluoropropene (HFO-1234ze), 2,3,3,3-tetrafluoropropene (HFO 1234yf), or mixtures thereof. The blowing agent compositions are useful in the production of low density insulating foams with improved R value.

Tetrafluoropropene based blowing agent compositions

A blowing agent for thermosetting foams is disclosed. The blowing agent is predominately the trans isomer of the hydrochlorofluoroolefin (HCFO) HFCO-1233zd alone or in combination with a hydrofluoroolefin (HFO), hydrofluorocarbon (HFC), hydrochlorofluoroolefin (HCFO), a hydrocarbon. The blowing agent is effective as a blowing agent in the manufacture of thermosetting foams.

Blowing agent composition of hydrochlorofluoroolefin

Disclosed is a combination of hydrofluoroolefins and/or hydrochlorofluoroolefins with stabilizers wherein the stabilizers minimize the degradation of the hydrofluoroolefins and hydrochlorofluoroolefins during storage, handling and use yet allow for atmospheric degradation. The combinations exhibit low or zero ozone depletion potential and lower global warming potential making them of interest as replacements for chlorofluorocarbons and hydrofluorocarbons. The combinations of the present invention comprise hydrofluoroolefins and/or hydrochlorofluoroolefins in combination with a stabilizer or stabilizers selected from free radical scavengers, acid scavengers, oxygen scavengers, polymerization inhibitors and combinations thereof.

Stabilized hydrochlorofluoroolefins and hydrofluoroolefins

The invention relates to heat transfer agents and heat transfer compositions containing hydrocarbon lubricating oils and halogenated alkene heat transfer fluid that promote oil flow and provide for improved oil return. The heat transfer compositions are useful in various heat transfer systems such as refrigeration, cooling, air conditioning, chiller operations.
