Abstract: A method for controlling plant diseases and unwanted microorganisms by incorporating N-halohydantoins in nutrient-watering solutions. In the method, a treatment mixture is prepared comprising plant nutrients, N-halohydantoin and water. A plant is contacted with the treatment mixture to inhibit disease or the growth of unwanted microorganisms on, in or around the plant, with the mixture also being viable for use in stimulating healthy plant growth.
Abstract: Highly fluorinated, saturated, C.sub.2 and C.sub.3 hydrofluorocarbons are efficient, economical, non-ozone-depleting fire extinguishing agents used alone or in blends with other fire extinguishing agents in total flooding and portable systems.
Abstract: Methods for extinguishing fires are disclosed which include the use of 2-Chloro-1,1,1,2-tetrafluoroethane as a fire extinguishing agent. The 2-Chloro-1,1,1,2-tetrafluoroethane may be used alone or in combination with other halogenated hydrocarbon fire extinguishants. Compositions including the 2-Chloro-1,1,1,2-tetrafluoroethane and other extinguishants are also disclosed. The compositions are effective at low concentrations and are non-toxic and environmentally safe.
Abstract: Halogenated styrene-based coatings having surprisingly good physical properties in combination with flame retardancy are prepared from copolymers of ring-halogenated, ethylenically unsaturated aromatic monomers and aliphatic conjugated dienes having from 4 to 10 carbon atoms, and from terpolymers of ring-halogenated, ethylenically unsaturated aromatic monomers, halogen-free aromatic monomers, and aliphatic conjugated dienes having from 4 to 10 carbon atoms.

Abstract: 2-(2-bromo-2-nitroethenyl)-furan can be used as an antimicrobial in broad spectrum of uses. A novel process for preparing 2-(2-bromo-2-nitroethenyl)-furan has been found in which furfural is reacted with bromonitromethane using a primary amine or primary amine salt as a catalytic agent to produce an intermediate product which is dehydrated in the presence of acid to the desired product. An antimicrobial composition comprising 2-(2-bromo-2-nitroethenyl)-furan and a carrier is also disclosed.
Abstract: A method for the treatment of nematodes includes applying to the nematodes in the soil a nematicidal amount of furfural. The furfural is preferably impregnated into the nematode-infested soil. The furfural may be applied neat or suspended in a variety of liquid or solid carrier systems, and is applied to the soil by methods including mixing, fumigation and injection. The furfural has excellent nematicidal effect at low concentrations, is cost effective, and is not phytotoxic.

Abstract: A process for preparing bromonitro-alcohols is disclosed in which bromonitromethane is reacted with a C.sub.1 -C.sub.3 aldehyde in aqueous solution at an acid pH, preferably between about 4.0 and about 7.0. An aqueous solution of the aldehyde is prepared and the pH adjusted to the desired acid range by addition of sodium bicarbonate, and the bromonitromethane is added thereto. The bromonitro-alcohol product is isolated as a separate phase from the reaction mixture.

Abstract: A synergistic mixture of 2-(2 bromo-2-nitroethenyl)furan and 2-bromo-2-nitropropane-1,3-diol is disclosed. The synergistic mixture can be used as an antimicrobial in a broad spectrum of uses; the synergistic mixture is effective against bacteria, algae and fungi. An antimicrobial composition comprising the synergistic mixture and a carrier is also disclosed.
Abstract: Flame retardant hot melt adhesives include atactic polypropylene having grafted thereon a ring-halogenated styrene. The compositions may also include homopolymers of the styrene monomer or equivalents, as well as non-halogenated atactic polypropylene.
