  • Patent number: 5344966
    Abstract: A cycloalkyl phosphorus compound is obtained by the catalytic hydrogenation of a substituted or unsubstituted aryl phosphonic acid using a heterogeneous catalyst which is a Group VIII metal on carbon. The hydrogenation is preferably effected in water. The catalyst can be ruthenium or carbon. When phenylphosphonic acid is used as the starting material, a yield of about 95% of essentially pure cyclohexylphosphonic acid can be obtained.

  • Patent number: 5324751
    Abstract: Free-flowing formations of spherules of loose knit microcrystals of the polymorphs of sorbitol and mannitol are useful in fast-frozen food products as cryoprotectants due to their improved rate of solubility and dispersion. The free-flowing formations are also helpful in formulating confectionary and pharmaceutical products by improving processing efficiencies and texture and are useful in selected industrial applications as a result of their improved rate of solution and free-flowing characteristics.

  • Patent number: 5316696
    Abstract: A composition comprises a poly(oxyalkylene)glycol derivative and a long chain anhydride and optionally a hydroxy-oxime. The long chain anhydride can be an alk(en)yl succinic anhydride in which the alk(en)yl group contains at least six carbon atoms. The optional hydroxy-oxime can be an alkyl-substituted benzaldoxime. The composition has improved corrosion resistance and can provide protection of a metal even in the form of a thin film.

  • Patent number: 5278205
    Abstract: The present invention relates to films or sheets of linear polyester containing glass spheres having a certain particle size distribution and in a certain amount based upon the weight of the polyester film. The addition of the glass spheres improves several properties of the film, including the dynamic coefficient of friction. Preferably, a second film additive, fumed silica, of a controlled particle size distribution and weight is additionally added to the film. The addition of the fumed silica additionally improves several properties of the polyester film, including the static coefficient of friction of the film.

  • Patent number: 5215581
    Abstract: A particulate inorganic solid, especially hydrated alumina or magnesium hydroxide, which has been treated with a hydroxybenzene derivative of a defined type, particularly a gallate. The treated solid may be incorporated into a polymer especially a thermoplastic polymer such as polypropylene. Alternatively, the solid, the hydroxybenzene derivative and the polymer can be blended together. The composition obtained can be processed even when containing 70% by weight of the inorganic solid.

  • Patent number: 5213701
    Abstract: A compound is a condensate of 1,2,3-trihydroxybenzene with an aldehyde. The condensate is a macrocyclic compound such as a cyclic tetramer. The aldehyde is preferably a long-chain aldehyde such as hexanal, dodecanal or tetradecanal. The condensate can be used as an anti-wear additive in hydrocarbon liquids such as liquid paraffin or as an anti-corrosion additive. The condensate can be prepared by reacting 1,2,3-trihydroxybenzene with an equimolar quantity of an aldehyde in the presence of an acid.

  • Patent number: 5185356
    Abstract: A particulate composition comprising an isothiazolinone or isothiazolothione or a salt or complex thereof and a water soluble metal salt. The salt is typically a metal salt, for example the sodium salt of 1,2-benzisothiazolin-3-one and the water soluble metal salt is particularly an alkali metal salt such as disodium hydrogen phosphate. A preferred composition can be obtained by stirring together an isothiazolinone or isothiazolothione, a base and an alkali metal phosphate in the presence of water until a dry particulate product is obtained. The particulate product is typically highly and rapidly soluble in water and may be stored in a container formed from a water soluble material, for example a bag formed from polyvinyl alcohol.

    Abstract: A composition comprising a chelating compound which is a macrocyclic compound containing at least two coordinating centers in the ring, at least one of which is a neutral base moiety, and an organic acid containing at least one alkyl or alkenyl group containing 8 or more carbon atoms. The macrocyclic compound contains at least 10 ring atoms and especially at least 12 ring atoms. The neutral base moiety is typically a nitrogen moiety. Preferably there are at least four coordinating centers at least two of which are neutral base moities. The acid can be an alkyl or alkenyl substituted acid for example a long chain carboxylic acid. The composition can be used as an extractant system for the selective extraction of metals from an aqueous phase into an organic phase.
