摘要:
A method of reducing sulfide odors in wastewater collection and treatment systems. The method includes adding nitrate ions in the form of a controlled release composition and microbes to the wastewater effective to reduce hydrogen sulfide levels. The controlled release composition can be in the form of a water-in-oil emulsion. The microbes can be aerobic and facultative Bacillus species.
摘要:
Sealant compositions for sulfur coated fertilizer particles are mixtures of wax materials and additives which provide improved moisture barrier properties and abrasion resistance. The sealants have penetration values measured by ASTM D-1321 of at least 20 at 25.degree. C., and congealing points measured by ASTM D-938 of between about 50.degree. C. and about 100.degree. C. The sealed fertilizer particles are conditioned with particulate materials with a surface area of at least about 2 m.sup.2 /g and an oil absorption of at least about 100%. A method for the production of abrasion resistant sulfur coated fertilizers is also disclosed.
摘要:
Granular pesticide compositions wherein a pesticide material is applied to a granular substrate using a carrier composition which provides improved adhesion of the pesticide to the substrate and abrasion resistance. The carrier composition may also provide controlled release of the pesticide.

A low foaming, rust inhibiting composition is disclosed which contains:A. a rust inhibiting amount of a dicarboxylic acid of the formula: ##STR1## wherein Z is COOH or H, and one of each is present, and x and y are from 3 to 9, with x+y=12;B. a foam inhibiting amount of a triglyceride acid of the formula: ##STR2## wherein x and y are integers from 3 to 9, x and y together equal 12. R.sub.1 and R.sub.2 are saturated/unsaturated hydrocarbon terminals of fatty acids esterified with glycerol; andC. a base sufficient to adjust the pH of the composition to about 6.5 to 10.5.
摘要:
Softener-antistatic compositions which are effective when added to a laundry wash cycle are water insoluble organic salts of a corboxylate anion containing a hydrocarbyl moiety with at least 10 carbon atoms and a quaternary ammonium cation containing two hydrocarbyl moieties with at least 12 carbon atoms each.
摘要:
The compositions of this invention are microemulsions having a. a surfactant consisting essentially of a mixture of one or more alkoxylated amines or alkoxylated quaternary ammonium salts and one or more preferably branched carboxylic acids or salts thereof, b. a solvent or oil that is liquid at 25° C. and is insoluble in water, and c. water, wherein an optically clear isotropic microemulsion is formed.
摘要:
Sequestrant compositions comprising combinations of an alkali metal or ammonium borate with an adduct formed by reaction of an .alpha., .beta. unsaturated polycarboxylic acid with a mono- or dicarboxylated sugar, in which the adduct has at least two hydroxy groups in a vicinal configuration. The sequestrants can be used to complex alkaline earth and transition metal ions and are especially useful for complexing calcium and magnesium in aqueous laundry solutions. They also are effective for soil dispersion and for inhibiting the deposition of soil on fabric.
