A process comprising introducing CO into milk of lime, in which the milk of lime is first ground, and then the CO is introduced to precipitate the calcium carbonate.

Process for preparing precipitated calcium carbonates

Bimolecular coated calcium carbonate and a process for controlled surface treatment of calcium carbonate according to which an amount of coating determined from the mean particle diameter (dp) of the calcium carbonate is contacted with the calcium carbonate particles. The way in which the amount of coating agent is determined enables purposeful control of the properties of the coated calcium carbonate particles to adapt them for use as functional filling materials in different technical applications.

Bimolecular coated calcium carbonate and process of production thereof

The invention relates to the use of polyglycerols in the manufacture of foods, in particular for influencing texture formation, water absorption capacity, freshness, inhibition of crystallization, protein denaturation and the improvement of the freeze and thaw stability and for fat replacement.

Cosmetic deodorant preparation containing di- or triglycerin esters

A method for treating waste water which contains organic and inorganic compounds, particularly waste water from the synthesis of epichlorohydrins, in which the waste water is subjected to

Process for treating waste water containing organic and inorganic

The present invention relates to a process for decreasing the content of organic-chemical substances in waste water by chemical oxidation, preferably in the presence of chlorine, and optionally additional alkaline thermal treatment of the waste water, in which the waste water, which has a COD content (chemical oxygen demand) and is alkaline or is rendered alkaline, is introduced into at least one reactor and is treated at a temperature of more than 15.degree. C. with a chlorine-containing and/or chlorine-releasing chemical substance, the introduction of chlorine taking place in a quantity of more than 1 g chlorine/g COD (relative to the chlorine content of the chlorine-containing and/or chlorine-releasing chemical substance), and a molar ratio of OH.sup.- to chlorine of more than 1.5 and a pH value of the waste water of .gtoreq.5 being maintained or set, and the resulting chlorine-treated, hypochlorite-containing waste water is subjected to a reaction time of more than 0.25 hours, with the organic compounds being at least partially oxidized, and subsequently the waste water is treated further and/or is discharged or drained from the reactor.

Process for treating waste water

A process for treating waste water containing chlorinated organic substances, particularly waste water from production of epichlorohydrin which contains more than 10 mg of adsorbable organic halogen compounds (AOX) per liter, comprising charging the waste water at a pH of 10 to 14 (measured at room temperature) into a reactor and maintaining a temperature of at least 75.degree.C., a pressure of at least 1 bar (abs.), and a residence time of at least 0.5 hours in said reactor, thereby partially dechlorinating and/or dehydrochlorinating chlorinated organic compounds contained in the waste water, and thereafter subjecting the waste water to further dechlorination and/or dehydrochlorination treatment in the presence of a hydrogen-containing gas, a hydrogen-releasing compound and/or a catalytically active material; and optionally subjecting the waste water to a biological treatment with the use of microorganisms; and apparatus for carrying out the foregoing process.

Process for treating waste water containing chlorinated organic

A process for the preparation of a composition containing diglycerol, in which process at least a stoichiometric amount of isopropylideneglycerol is reacted with .alpha.-monochlorohydrin in the presence of at least one alkaline compound at sufficient temperatures to yield an intermediate product composition containing monoisopropylidenediglycerol and a salt. Most of the salt and water formed is removed from the intermediate product composition, and any unreacted isopropylideneglycerol is removed by distillation. The remaining intermediate product composition containing monoisopropylidenediglycerol is subsequently reacted with water in the presence of at least one acidic catalyst at sufficient temperatures to yield a product composition containing diglycerol and acetone and substantially no cyclic glycerols.

Process for the preparation of diglycerol and/or polyglycerol
