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.

[object Object]

Provided is a composition comprising (a) at least one halogenated compound selected from the group consisting of C-Chydrofluoroolefin, CFI, and combinations thereof, and (b) an effective stabilizing amount of a sesquiterpene selected from the group consisting of farnesol, farnesene, and mixtures thereof.

Sesquiterpene stabilized compositions

Use of molecular sieves to reduce the amount of trifluoromethane (HFC-23) present in a mixture of HFC-23 with other materials, particularly from mixtures containing HFC-23 and trifluoroiodomethane (CFI).

Use of molecular sieves for the removal of HFC-23 from fluorocarbon products

Disclosed are methods of producing supported organic catalyst systems which find particular use in polymerization reactions. The methods comprise generally, the steps of (a) providing an organic catalyst solution comprising an organic catalyst dissolved in a solvent; (b) contacting the organic catalyst solution with a solid support material; and (c) removing the solvent from the support material by using one or more supercritical-like solvents.

Supported catalyst systems

Disclosed are methods of producing a supported organic catalyst system comprising the steps of: (a) providing an organic catalyst solution comprising an organic catalyst dissolved in a supercritical-like solvent; (b) contacting a support material with the organic catalyst solution; and (c) removing substantially all of the supercritical-like solvent from the organic catalyst and the support material.

Provided are methods of charging refrigerants into refrigeration systems. The present methods involve recharging a refrigerant system that contains a chlorine-containing refrigerant and a lubricant comprising the steps of (a) providing a refrigeration system comprising a chamber having a hydrocarbon-based lubricant and substantially no chlorofluorocarbon refrigerant; and (b) introducing to the system a composition comprising: (i) a refrigerant; (ii) a surfactant; and (iii) a solubilizing agent.

Method of introducing refrigerants into refrigeration systems

The present invention relates to novel compositions of drying agents of superabsorbent polymers, molecular sieves and mixtures thereof and binders of polyurethane foam, polyisocyanurate foam and supports comprising cellulose and a method for separating, drying and/or filtering chemical mixtures. The composition and method of the invention have broad applicability. They may be used for example to remove water from chemical mixtures like refrigerants (e.g., in vehicular refrigeration systems), air (e.g., in vehicular braking systems), natural gas and cleaning solvents (e.g., used in semiconductor manufacture and pipeline cleaning).

Process for separating water from chemical mixtures

Provided are methods of introducing environmentally desirable refrigerants into refrigeration systems. The present methods involve recharging a refrigerant system that contains a chlorine-containing refrigerant and a lubricant comprising the steps of (a) removing the chlorine-containing refrigerant from the refrigeration system while retaining a substantial portion of the lubricant in said system; and (b) introducing to said system a composition comprising: (i) a refrigerant; (ii) a surfactant; and (iii) a solubilizing agent.

Cleaning a component of a vapor compression system with a cleaning composition having a hydrofluorocarbon as an active ingredient.

Cleaning vapor compression systems

A method for separating water from a chemical mixture is provided. In the process of the invention, water is separated from a chemical mixture by contacting the chemical mixture with a water-soluble polymer.

Azeotrope-like compositions of trifluoromethane, carbon dioxide, ethane, and hexafluoroethane are provided. The compositions of the invention are environmentally desirable for use as refrigerants, aerosol propellants, blowing agents for polymer foam, heat transfer media, and gaseous dielectrics.
