Abstract: A closure having a device for lifting a liner from a container opening. The lifting device being a finger projecting from a hinge connection within the closure. The hinge connection is positioned from a depending skirt of the closure. The hinged finger disengages the liner from a sealing engagement with the container while engaging along substantially the same annulus spaced from the liner edge. A plurality of the hinged fingers may be used for the lifting device. The closure may be used in various retort and aseptic applications, as well as provide for tamper indication.

Abstract: The present invention relates to an aqueous cleaning composition used to remove unwanted organic and inorganic residues and contaminants from semiconductor substrates. The cleaning composition comprises a urea derivative such as, for example, dimethyl urea, as the component that is principally responsible for removing organic residues from the substrate. A fluoride ion source is also included in the cleaning compositions of the present invention and is principally responsible for removing inorganic residues from the substrate. The cleaning compositions of the present invention have a low toxicity and are environmentally acceptable.

Abstract: A curable epoxy resin composition comprising a polyepoxide resin and an amine curative characterized in that the amine curative comprises a partially methylated polyalkylene polyamine having at least three amine nitrogens and at least two active amine hydrogens.

Abstract: This invention relates to improved polyepoxide resins having enhanced physical and elastic properties. The polyepoxide resins comprise a polyepoxide resin based on a polyglycidyl ether of a phenolic-type compound and an acrylate-terminated urethane prepolymer. The improvement in the polyepoxide resin formulation comprises incorporating a polymethylated amine curative having two secondary amine hydrogens represented by the formula: ##STR1## wherein R is alkylene or polyalkylene polyamine having from 2 to 20 carbon atoms. The presence of the aliphatic amine reactive component along with the acrylate-terminated urethane prepolymer results in an epoxy resin having enhanced properties.

Abstract: This invention relates to an improved process for preparing dihydroperoxyalkanes and, particularly, dimethyldihydroperoxyhexane. The improvement resides in utilizing a tetrahydrofuran derivative which is a liquid as a feedstock. This feedstock then is reacted with hydrogen peroxide in the presence of sulfuric acid to form the dihydroperoxide.

Abstract: A process is disclosed for making a highly fluorinated aromatic compound by contacting a perfluorocycloalkane, such as perfluorodecahydronaphthalene, with a complex of a metal from Groups IA and IIA of the Periodic Table and an organic electron acceptor. The reaction is carried out in an organic solvent and under reducing conditions which are relatively moderate. Best results are obtained using a perfluorocycloalkane having 2-4 condensed rings and a complex of either sodium or lithium and benzophenone thereby making a perfluorinated condensed ring aromatic compound such as perfluoronaphthalene or perfluorophenanthrene.

Abstract: The present invention is a process for the selective synthesis of alkanediamines by reacting a secondary amine with an alkanediol. High conversions and high selectivity for the production of alkanediamines is achieved by carrying out the reaction in the presence of a compound or complex of ruthenium in the absence of an organic phosphine co-catalyst.

Abstract: Selective mono- or di-amination of alkanediols is controllably obtained by catalytic reaction with secondary amines at moderate temperature and autogenous pressure, by selection of the catalyst employed. Ruthenium complexes compounded or admixed with selected organic phosphines, such as triphenylphosphine, favor high yields of alkanolamines, while ruthenium complexes in the absence of organic phosphines favor production of alkylenediamines. Iridium complexes with or without organic phosphines in admixture or chemical combination, also promote production of alkylenediamines.

Abstract: The present invention comprises a process for the synthesis of hydroxyalkyl amines, hydroxyalkyl piperazines, or alkyl piperazines from alkylene glycols and ammonia or alkyl amines using a substantially soluble transition metal carbonyl complex catalyst precursor.

Abstract: The present invention is a process for the synthesis of tertiary alkanolamines by reacting a secondary amine with an alkanediol. High selectivity for the production of alkanolamines is achieved by carrying out the reaction in the presence of a compound or complex of ruthenium in chemical combination or in admixture with an organic phosphine ligand. The organic phosphine ligand is present in an amount such that the ratio of gram mole ligand/gram atom ruthenium is greater than 5.

Abstract: In the catalytic reaction of ammonia or formamide with CO and H.sub.2, exceptionally high yields of mono- and di-methyl formamide are obtained among the reaction products when the reaction is carried out in the presence of a platinum group catalyst soluble in the reaction medium, particularly a compound or complex of ruthenium or rhodium, employing a relatively non-volatile polar solvent which does not contain an active methyl function and which does not enter into the reaction producing formamide compounds. The pressure employed is in the range of 3000-8000 psi with a hydrogen partial pressure of at least 1500 psi, the preferred solvent being sulfolane.

Abstract: This invention relates to a process for producing tertiarydiamine-boranes by reacting a tertiary diamine with a borohydride in the presence of a carboxylic or mineral acid source. Water is included in the reaction medium in a catalytic amount but insufficient for forming two phases. Excellent selectivity to tertiary diamine-boranes is achieved.
