Three enzymes degrading sulfated glucuronofucan; processes for producing these enzymes; activators for these enzymes; glucuronofucan sulfate and degradation products thereof; and a novel microorganism.

A beta-1,3-glucan of sulfated curdlan having a sulfur content of 12.4 to 17% and an average molecular weight of 27,000 to 330,000 daltons. Sulfate curdlan exhibits strong HIV inhibitory activity with little anticoagulant activity and little toxicity.

A chromium VI reducing composition comprising particles of solid material selected from the group consisting of iron (II) sulfate and tin sulfate, the particles being substantially uniformly dispersed within a liquid carrier. Methods for modifying hydratable cementitious materials using the chromium reducing composition are also disclosed and provide advantages over dry powder or dissolved forms of sulfate compositions when used in cement manufacturing.

A method and apparatus for sulfate analysis in a sample are provided. A portion of the sulfate contained in the sample is converted to sulfur dioxide, and at least a portion of the sulfur dioxide can be determined. The amount of sulfur dioxide determined can be used to quantify the amount of sulfate in the sample.

A process for removing sulfates such as hydrogen sulfate, sodium sulfate, and chloride from an ethanol stream by contacting the ethanol stream with a clay material to thereby remove at least a portion of the sulfates.

Fluorgyp is converted to calcium sulfate by reacting sulfuric acid in the fluorgyp with calcium carbonate having a small particle size. The resulting product is useful as a set retarding agent for cement.

The present invention relates to a (a) novel silicone sulfate, (b) a method for preparation of said sulfate and (c) application of said sulfate in The compounds of the present invention are made by reacting certain epoxy containing silicone compounds and sodium sulfate under aqueous conditions. The resulting compound is quite stable and offers excellent foam in personal care applications.

The liquid cooling spray in a gas conditioning chamber is modified by the addition of an alkali to scrub sulfuir dioxide and other acid forming gases and a separation unit to remove particles that may contain either unreacted alkali or salts of the acid forming gases. A slurry of fine particles of hydrated lime is injected into the liquid coolant under conditions that result in kernels of controllable size that contain the alkali or salts from reactions with the acid forming gases. The modified ...

Ammonium sulfate nitrate composite materials useful as fertilizers having desirable levels of nitrate ions, superior stability against detonation, higher density, greater resistance to moisture, and a method for their manufacture. The ammonium sulfate nitrate composites have as essential constituents ammonium sulfate and the NH.sub.4 SO.sub.4.2(NH.sub.4 NO.sub.3) double salt with less than 5 wt. % in combined total of the more hazardous NH.sub.4 SO.sub.4.3(NH.sub.4 NO.sub.3) double salt and ammo...

This invention relates to a method of inhibiting the growth of barium sulfate scaling by using a synergistic blend of (a) a polyphosphate with degree of polymerization between 6 and 21, and (b) a polyphosphate with degree of polymerization of 2-3 in a weight ratio of 3:1 to 1:2. The blend further includes a phosphino-acrylic polymer.
