    摘要: The present invention provides an improved method for sorbing aqueous fluids through the use of a biodegradable, clumping, low odor, low attrition, low swelling ground grain litter. The ground grain litter is composed of a ground grain selected such that when the ground grain is wetted it tends to swell in volume less than 100%. In preferred embodiment, the ground grain litter comprises ground hard red spring wheat used to sorb pet urine and fecal liquids voided by a pet into the litter.

    摘要: Tall oil pitch is used as casing fillers in the interstitial spaced between a pipeline and a surrounding casing pipe. The tall oil pitch can be used per se or can be modified by: increasing its specific gravity above 1.0; increasing its pour point or dropping point; increasing its viscosity; decreasing its pumpability temperature. The tall oil pitch is pumped into the interstitial space between the pipeline and the casing pipe.

    摘要: Organophilic polyphenolic materials which are effective fluid loss control additives for oil base well-working fluids are prepared from a polyphenolic material and one or more phosphatides. Preferred phosphatides are phosphoglycerides obtained from vegetable oils, most preferably commercial lecithin. Preferred polyphenolic materials comprise one or more of: humic acid; lignosulfonic acid; lignins; phenolic condensates; tannins; the oxidized, sulfonated, or sulfomethylated derivatives of these polyphenolic materials; and the water soluble or colloidally dispersible salts of these polyphenolic materials or these derivatives thereof.

    摘要: The invention provides novel humic acid derivatives obtained by reacting humic acid-containing materials with a noval amide mixture comprising a polyamide and an amido-amine containing one free amino group per molecule. The novel amide mixture is obtained by reacting under amidation conditions a fatty acid containing 16 to 30 carbon atoms with an amine mixture comprising aminoethylethanolamine (AEEA) and one or more polyethylenepolyamines (PEPA) containing 3 or more amino groups per molecule, wherein the weight ratio of AEEA/PEPA is in the range from about 0.25/1 to about 3/1, and wherein the amount of fatty acid is less than the amount required to amidate all of the amino groups and greater than the amount required to amidate all but one amino group per molecule.
