The invention provides polyurethane and polyisocyanurate foams and methods for the preparation thereof. More particularly, the invention relates to closed-celled, polyurethane and polyisocyanurate foams and methods for their preparation. The foams are characterized by a fine uniform cell structure and little or no foam collapse. The foams are produced with a polyol premix composition which comprises a combination of a hydrohaloolefin blowing agent, a polyol, a silicone surfactant, and a non-amine catalyst used alone or in combination with an amine catalyst.

Catalysts for polyurethane foam polyol premixes containing halogenated olefin blowing agents

The invention provides polyurethane and polyisocyanurate foams and methods for the preparation thereof. More particularly, the invention relates to open-celled, polyurethane and polyisocyanurate foams and methods for their preparation. The foams are characterized by a fine uniform cell structure and little or no foam collapse. The foams are produced with a polyol premix composition which comprises a combination of a hydrohaloolefin blowing agent, a polyol, a silicone surfactant, and a sterically hindered amine catalyst.

The invention provides polyurethane and polyisocyanurate foams and methods for the preparation thereof. More particularly, the invention relates to polyurethane and polyisocyanurate foams having an open-cell, closed-cell or a combination of open and closed cell structure, and methods for their preparation. The foams are produced with a polyol premix composition which comprises a combination of a hydrohaloolefin blowing agent, a polyol and a catalyst which is an adduct of an amine and an organic acid.

Stabilization of polyurethane foam polyol premixes containing halogenated olefin blowing agents

In certain non-limiting, aspects, the present invention relates to storage stable premixes of a polyol suitable for polyurethane or polyisocyanurate foam preparation having, at least, 1,1,1,4,4,4-hexafluoro-2-butene (1336mzzm) as the blowing agent and optional one or more additional additives and/or auxiliary blowing agents in amounts suitable for polyurethane or polyisocyanurate foam preparation.

Disclosed are processes for the production of fluorinated olefins, preferably adapted to commercialization of CFCF&#x2550;CH(1234yf). Three steps may be used in preferred embodiments in which a feedstock such as CCl&#x2550;CClCHCl (which may be purchased or synthesized from 1,2,3-trichloropropane) is fluorinated (preferably with HF in gas-phase in the presence of a catalyst) to synthesize a compound such as CFCCl&#x2550;CH, preferably in a 80-96% selectivity. The CFCCl&#x2550;CHis preferably converted to CFCFClCH(244-isomer) using a SbClas the catalyst which is then transformed selectively to 1234yf, preferably in a gas-phase catalytic reaction using activated carbon as the catalyst. For the first step, a mixture of CrOand FeCl/C is preferably used as the catalyst to achieve high selectivity to CFCCl&#x2550;CH(96%). In the second step, SbCl/C is preferably used as the selective catalyst for transforming 1233xf to 244-isomer, CFCFClCH. The intermediates are preferably isolated and purified by distillation and used in the next step without further purification, preferably to a purity level of greater than about 95%.

Method for producing fluorinated organic compounds

The invention pertains to heat transfer compositions, particularly to automobile refrigerants comprising a hydrofluoroalkene, an iodocarbon, and at least one lubricant having hydrogen atoms and carbon atoms, wherein no more than 17% of the total number of hydrogen atoms which are attached to a carbon atom are tertiary hydrogen atoms.

The invention provides foam forming methods that comprise: (a) preparing a foamable system comprising at least one hydrohaloolefin; and (b) ensuring either (i) the substantial absence of long-term decomposition-inducing contact between said hydrofluoroolefin and an amine-containing catalyst; (ii) that an effective amount of surfactant is available in the system under conditions which prevent long term exposure of the surfactant to a long-term decomposition reaction environment; or (iii) a combination of (i) and (ii). Related methods, foamable systems and foams are also disclosed. Preferred embodiments provide polyurethane and polyisocyanurate foams and methods for the preparation thereof, including closed-celled, polyurethane and polyisocyanurate foams and methods for their preparation. The preferred foams are characterized by a fine uniform cell structure and little or no foam collapse. The foams are preferably produced with a polyol premix composition which comprises a combination of a hydrohaloolefin blowing agent, a polyol, a silicone surfactant, a catalyst and is further characterized by being substantially free of added water.
