  • Patent number: 5614473
    Abstract: Increased foam quality and resistance to hydrocarbon defoaming for foams used in well boring and stimulation processes as well as secondary and tertiary oil recovery is obtained using imidazoline-based amphoacetates of higher purity, containing essentially negligible amounts of unalkylated amido amines, lower amounts of glycolic acid salts and monochloroacetate salts.The higher purity amphoacetates can be obtained via processes utilizing precise pH control during the reaction of imidazoline, or its open-chain derivatives, with alkylating agents, e.g. sodium monochloroacetate. These higher-purity amphoacetates contain essentially fully alkylated products and lower amounts of glycolic acid derivatives, even though a ratio of monohaloalkylate to substituted imidazoline, or its open-ring derivative, of less than 1.5:1.0 and close to 1.0:1.0 is used.

  • Patent number: 5585131
    Abstract: A cereal or grain hydrolysate-containing composition which is derived from the enzymatic, e.g., amylase, hydrolysis of cereal or grain in combination with a hydrocolloid, preferably carrageenan or a blend of xanthan gum and locust bean gum, can be effectively used as a fat mimic in preparing low fat comminuted meat products.

  • Patent number: 5567788
    Abstract: A liquid resin-forming composition contains a polyether-ene such as a polyallyl glycidyl ether, a free radical-polymerizable monomer such as an acrylate ester, a free radical initiator such as an organic peroxide and/or an organic hydroperoxide and a promoter such as an amine and/or polyvalent metal carboxylate. Certain properties of the composition, specifically, its volatiles content, flash point and viscosity, can be such as to make the composition particularly useful for application to a solid permeable substrate such as a concrete structure where, upon curing, the resulting resin will heal and/or seal pores and/or small cracks in the substrate preventing or lessening its penetration by liquids.
