Abstract: The present invention relates to biocidal compositions comprising an isothiazolone biocidal active compound in combination with a guanidine adjuvant. These compositions are highly effective in preventing deterioration and decay caused by microbial contamination in very low concentrations so that the environmental or toxicological burden is low.

Abstract: A composition containing a quaternary organosilane foaming agent capable of foaming various liquids in order to remove the liquids from subterranean wells is described. For instance, the composition can be used to remove hydrocarbon condensate liquids from a gas well or an oil well. Of particular advantage, the composition can foam liquids containing substantial amounts of hydrocarbons.

Abstract: The invention relates to a method for the prevention and removal of H2S and/or other sulfhydryl compounds and iron sulfide deposits from gas and/or liquid streams in industrial process systems. Formulations comprising aldehydes, aldehyde donors, and/or aldehyde stabilizers, excluding triazines, in combination with the reaction product of an amino acid and a hydroxymethylphosphine or hydroxymethylphos-phonium salt, and optionally a quaternary ammonium compound and/or one or more N-hydrogen compounds such as 5,5-dialkylhydantoin or amines, are rapidly and sustainedly scavenging H2S originating from process and/or microbial sources. The formulations possess high capacities for H2S removal and are relatively pH-insensitive.

Abstract: Microbial growth in an aqueous system containing borohydride residues is controlled by adding an aldehyde or aldehyde source, followed by adding an active halogen biocide. The active halogen biocide is preferably stabilized by an N-hydrogen compound.

Abstract: A process is provided for the preparation of a novel polyaluminum calcium hydroxychloride composition of enhanced efficiency for water treatment, paper sizing, and antiperspirant applications. The polyaluminum calcium hydroxychloride compositions are prepared via the acidification of higher basicity reaction products to form mid-to-high basicity final products. Two methods are provided for the preparation of higher basicity products, contemplated in the first, and an aqueous acid solution, such as hydrochloric acid, aluminum chloride, or a mixture thereof, is mixed with a strong alkaline calcium salt such as calcium oxide or calcium carbonate and aluminum powder at temperatures greater than 60° C. In a second method, bauxite, aluminum hydrate, or aluminum metal, and calcium aluminate are mixed with hydrochloric acid and are reacted at high temperatures and/or elevated pressures for a certain period of time whereby, when the reaction is complete, the mixtures are filtered to obtain clear solutions.

Abstract: Novel aluminum antiperspirant compositions of enhanced efficacy activated by both heat and acid are produced comprising basic aluminum salts of having the formula: Al2(OH)6-aXa ?wherein X is Cl?, Br?, l?, or NO3?, a is from abut 1.1 to about 1.7, with basic aluminum chloride being the preferred salt. When analyzed by SEC-HPLC at about 10% concentration (i.e., by 2% Al) in water, these compositions exhibit an SEC-HPLC Band I area of less than 10%, a Band III area of at least 20%, with a Band III/II area ratio of at least 0.7, a Band IV area of at least 20%, and have at least 60% aluminum species contained in Bands III and Band IV.

Abstract: The production of polyaluminum hydroxychlorosulfates (PACS) suitable for effective use as flocculants and coagulants in water treatment is described. The product is a fluid, clear solution that is stable with respect to precipitation and gelling for extended periods of time. Key features of the process include: i) the production of a PACS solution of about 12-16% Al2O3 and about 40-60% basicity at moderate temperatures (50-60° C.) using a zerovalent aluminum source, such as aluminum powder, ii) the addition of an alkali metal or alkali earth metal base at low temperatures (20-30° C.
