Abstract: A surfactant component and a composition comprising the same are provided. The surfactant component comprises a first surfactant, a second surfactant, and water. The first surfactant comprises an alcohol alkoxylate having a high degree of alkoxylation of greater than 30 to 150. The first surfactant is present in an amount of from 1% to 50% by weight based on the total weight of the surfactant component. The second surfactant is present in an amount of at least 5% by weight based on the total weight of the surfactant component. Water is present in an amount of from 20% to 90% by weight based on the total weight of the surfactant component. The second surfactant enables higher concentrations of the first surfactant in water to be achieved without gelling than what has been accomplished to date.

Abstract: A method of removing from and preventing scale from depositing in underground petroleum containing formations and upon equipment used to inject high brine scale forming waters into such formations which comprises treating such waters with a scale inhibiting amount of an acrylic acid polymer which contains from 0-95 mole percent of acrylamide and from 1-30 mole percent of amido C.sub.1 -C.sub.6 alkyl phosphonate groups from the group consisting of:a) Amidomethyl phosphonate groups,b) Alpha-hydroxy-beta-amidoethyl phosphonate groups,c) Alpha-hydroxy-beta-amidoisopropyl phosphonate groups, and,d) Amidopropyl phosphonate groups said polymer having a molecular weight range between 1,000-100,000.

Abstract: The invention describes novel amino(lower alkyl)phosphinic acid compounds and their use to modify acrylamide polymers, acrylic acid polymers and acrylamide-acrylic acid co-polymers which produces polymers containing amidoalkylphosphinic acid groups.

Abstract: A method of preventing scale from depositing in underground petroleum-containing formations and upon equipment used to inject into or remove from such formations high brine, scale-forming waters. This method comprises treating such waters with a scale-inhibiting amount of an acrylic acid or acrylamide homopolymer or co-polymer of acrylic acid with acrylamide having a molecular weight within the range of 1,000-50,000 which have been modified to contain up to about 30 mole percent of amido(C.sub.2 -C.sub.6 alkyl)phosphinic acid groups and the alkali metal, ammonium and amine salts thereof.

Abstract: The invention describes acrylamide, acrylic acid, polymers and co-polymers containing phosphinate groups to inhibit scale and corrosion caused by metal surfaces contacting industrial waters.

Abstract: A monosecondary amine containing blocked primary amine groups is provided by reacting a monosecondary amine containing at least one primary amine group (such as diethylene triamine) with a ketone which is hindered to prevent reaction with secondary amino hydrogen atom (such as methyl isobutyl ketone) while removing water. This product disperses in water with the aid of a solubilizing acid to provide a solution which will emulsify a liquid polymer dispersed therein. The water hydrolyzes the blocked primary amine groups to restore reactivity. This product can also be reacted with 1,2-oxirane or isocyanate-functional polymers to provide products which are dispersible in water with a solubilizing acid. These dispersions will electrodeposit at the cathode.
