Abstract: Refrigeration fluid compositions for compression refrigeration which have an upper solution critical temperature equal to or greater than about 35.degree. C. are composed of selected hydrochlorofluorocarbons and hydrofluorocarbons with esterified polyether polyols in which at least 30% of the hydroxyls are esterified. The esterified polyether polyols have a viscosity between 25 and 150 centistokes at 38.degree. C.

Abstract: Lubricant base compositions for compression refrigeration are composed of 95 to 5% by weight of polyether polyols having a number average molecular weight from about 400 to about 5000 and 5 to 95% of esters made from polyhydric alcohols with alkanoic acids or esters made from alkanedioic acids with alkanols. A refrigeration fluid is made from the base composition with the addition of selected hydrochlorofluorocarbons and hydrofluorocarbons so that the base composition is miscible with the refrigerant in the range from -20.degree. C. to greater than 65.degree. C.

Abstract: Synthetic lubricants comprising 15 to 45 weight percent of an ester of a monohydric alcohol of 4 to 18 carbon atoms with one or more aromatic or alkane dicarboxylic acids having 4 to 18 carbon atoms blended with 85 to 55 weight percent of one or more polyether polyols having a number average molecular weight from about 400 to 5000. The blends are compounded with antioxidants, corrosion inhibitors, and metal deactivators to produce a superior lubricant for reciprocating air compressors which gives a long life to the compressors.

Abstract: Novel bis(dithiocarbamate) salts, the mixed transition metal salts, and zinc salt amine complexes thereof are claimed. These novel compounds have utility as antifungal agents.

Abstract: Chelate resins are obtained by introducing an effective amount of chelate active groups into the cured reaction product of an epoxide and a polyalkylenepolyamine. For example, an alkali metal salt of a halogenated carboxylic acid such as sodium chloroacetate, is reacted with the reaction product of triethylenetetraamine and diglycidyl ether of bisphenol A to form a chelate resin.

Abstract: The reaction product of an epoxide and a polyalkylenepolyamine is prepared in bead form by dispersing a blend of the epoxide and polyalkylenepolyamine in a concentrated aqueous solution of an alkali metal hydroxide and then curing the dispersed blend. For example, dispersing a blend of triethylenetetramine and diglycidyl ether of bisphenol A in an agitated aqueous solution of 50 weight percent NaOH and curing the dispersed blend produces normally solid beads which are useful as a weak base ion exchange resin.

Abstract: The cured reaction product of a polyalkylenepolyamine and a polyepoxide is useful as a weak base ion exchange resin. For example, the reaction of triethylenetetramine and diglycidyl ether of bisphenol A forms a weak base resin having an excellent total weak base capacity.
