  • Patent number: 6495722
    Abstract: Provided herein are polyurethane foams which may be prepared by spray techniques. The foams of the invention are prepared using conventional isocyanates and a novel Mannich condensate polyol having a hydroxy number in the range of 250-340 and a viscosity of 3500 cps or less, and wherein the Mannich condensate polyol is derived from nonylphenol, formaldehyde, an alkanolamine, and propylene oxide as the sole alkoxylating agent. Polyurethane foams prepared according to the invention possess superior physical properties over sprayed polyurethane foams prepared using Mannich condensate polyols which are made using mixtures of propylene oxide and ethylene oxide.

    Abstract: A process of reforming an alkyleneamine feedstock or a mixture of such feedstocks to an alkyleneamine or a mixture of alkyleneamines which is different from the feedstock or feedstock mixture. The process is catalyzed by one of the following: Group VB metal oxides, Group VB metal phosphates, Group IIA metal silicates, and tungsten oxides. For example, ethylenediamine is contacted with a catalyst of niobic acid or magnesium silicate to yield predominantly diethylenetriamine and non-cyclic triethylenetetramines; whereas high molecular weight polyethylenepolyamines are cracked by the same catalysts to mixtures of lower molecular weight linear and cyclic materials.

  • Patent number: 5298483
    Abstract: The present invention is directed to a new matter of composition in the form of chemical compounds and to a method for enhancing plant growth and the properties exhibited by plants treated with the compounds in accordance with this method. In particular, application of the compounds results in an increase in sugar content, essential oils and proteins along with an increase in total plant biomass. Fruits harvested from treated plants exhibit an accelerated biochemical and structural maturity. Citrus fruits typically show a reduced peel thickness and exhibit significant improvements in vitamin C, carotenoid, and essential oil contents. The methods of the present invention produce balanced improvements in the structural, biochemical, and sensory quality of Citrus fruits.
