The present invention provides a composition comprising 2,3,3,3-tetrafluoropropene and &#x3b1;-terpinene particularly useful in automotive air conditioning systems and devices, commercial refrigeration systems and devices, chillers, residential refrigerator and freezers, general air conditioning systems, heat pumps, and the like.

HFO-1234yf inhibited solutions

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.

Amine catalysts for polyurethane foams

A copolymer comprising trans-1,3,3,3-tetrafluoropropene units and vinylidene fluoride units, and methods of making the same. A method of preventing biofouling on an article of manufacture, comprising applying such copolymer to the article of manufacture. A process of preparing a surface having a surface energy of between about 20 and about 30 mJ/m, comprising applying such a copolymer to a support. A method of preventing accumulation of ice on an article of manufacture, comprising applying such a copolymer to an article of manufacture. A method of preparing a polymer, comprising a step of adding trans-1,3,3,3-tetrafluoropropene/vinylidene fluoride copolymer as a polymer processing additive/aid to said polymer.

Synthesis and use of trans-1,3,3,3-tetrafluoropropene/vinylidene fluoride copolymers

The present invention provides a composition comprising 2,3,3,3-tetrafluoropropene and &#x3b3;-terpinene useful in automotive air conditioning systems and devices, commercial refrigeration systems and devices, chillers, residential refrigerator and freezers, general air conditioning systems, heat pumps, and the like.

Disclosed are aqueous emulsion copolymerization processes for synthesizing 2,3,3,3-tetrafluoropropene/vinylidene fluoride copolymers having 2,3,3,3-tetrafluoropropene as the major monomer unit. The copolymerization process is performed at temperatures of from about 55&#xb0; C. to about 70&#xb0; C. with at least one water soluble radical initiator, with preferred initiators including NaSO, KSO, (NH)SO, Fe(SO), KSO/FeSO, (NH)SO/FeO, and the like, as well as combinations thereof.

Synthesis of 2,3,3,3-tetrafluoropropene/vinylidene fluoride copolymers

Fumigant compositions including hexafluoropropylene oxide (HFPO) and methods of preparing such compositions are provided. The fumigant compositions may be suitable for use as soil fumigant compositions and structural fumigant compositions against a variety of undesirable species such as weeds, nematodes, pathogens, animals and insects. The fumigant compositions also have low toxicity and low Global Warming Potential (GWP).

Fumigant compositions and methods based on hexafluoropropylene oxide (HFPO)

In accordance with the present invention, aqueous emulsion polymerization processes of synthesizing 2,3,3,3-tetrafluoropropene/vinylidene fluoride copolymers having 2,3,3,3-tetrafluoropropene as the major monomer unit are provided.

A method for treating process distillate heavies produced during uranium fluoride purification is described. The heavies contain primarily uranium hexafluoride, UF, and molybdenum oxytetrafluoride, MoOF. The uranium hexafluoride is removed via distillation at reduced pressure leaving essentially MoOFcontaining &#x3c;0.1% of residual uranium hexafluoride. This mixture is hydrolyzed in water, then treated with a solution of sodium hydroxide until a pH of at least 7.5 is reached. The precipitated sodium diuranate and sodium fluoride are removed by filtration. The filtrate is reacted with calcium chloride to precipitate the molybdenum values as calcium molybdate containing trace quantities of calcium fluoride.

Separation and recovery of molybdenum values from uranium process distillate

Disclosed is a one step process for making of 1,1,1,4,4,4-hexafluoro-2-butene. More specifically, the present invention provides a process for making hexafluoro-2-butene, continuously, from 2-chloro-3,3,3-trifluoropronene using FeO/NiO impregnated carbon catalyst at 600&#xb0; to 650&#xb0; C.

One-step process for hexafluoro-2-butene

Fumigant compositions including hexafluoropropene or 1,1,3,3,3-pentafluoropropene, and methods of preparing such compositions, are provided herein. The fumigant compositions may be suitable for use as soil fumigant compositions and structural fumigant compositions against a variety of undesirable species such as weeds, nematodes, pathogens, animals and insects. The fumigant compositions also have low toxicity and low Global Warming Potential.

Fumigation methods

To address the problem of insufficient biodegradability of perfluorinated surfactants, the present invention provides biodegradable fluorosurfactants derived from olefins having &#x2014;CHR, &#x2014;CHRf, &#x2014;CHF, and/or &#x2014;CHgroups, where R is an alkyl group and Rf is a perfluoro or fluroroalkyl group. Preferably, the &#x2014;CHR, &#x2014;CHRf, &#x2014;CHF, and/or &#x2014;CHgroups are contained within partially fluorinated alkenes.

Fluorosurfactants having improved biodegradability

The present invention provides routes for making 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd) from commercially available raw materials. More specifically, this invention provides routes for HCFO-1233zd from inexpensive and commercially available trifluoromethane (HFC-23).
