A method of removing mercury from a process gas by means of a sorbent and a filter (10) involves applying said sorbent to at least one filtering surface (12) of the filter (10). A first parameter, which is indicative of the amount of mercury that needs to be removed in said filter (10), and a second parameter, which is indicative of the amount of material that has been collected on said filtering surface (12), are measured. A measured value of said first parameter is compared to a mercury set point. When said measured value of said first parameter is higher than said mercury set point, the cleaning of said filtering surface (12) is delayed, compared to the point in time suggested by a measured value of said second parameter.

A redispersible polymer including, as a redispersing aid, a protective colloid system including from 30% to 100% of a low molecular weight polyacrylamide colloid having a 20% solution viscosity in water of 200 to 800 Centipoise.

Yield and selectivity of olefin acetoxylation are improved through the use of successive catalyst zones of different reactivities, the successive zones contained in one or more reaction tubes arranged is parallel.

In a feed pump designed as a side-channel pump, an impeller is held so as to be slightly pivotable with respect to a shaft about an axis running transversely to the shaft. The impeller is thereby adaptable to tolerances of a casing. Rubbing of the impeller on the casing is also prevented as a result. The feed pump consequently generates a particularly low level of noise.

The invention provides a process for preparing emulsions of organopolysiloxanes (O), which includes polymerizing: (1) 100 parts by weight of hydroxyl-terminated organopolysiloxanes and (2) at least 0.01 part by weight of trialkylsilyl-terminated organopolysiloxanes having a viscosity of at least 55 mm2 / s in the presence of (3) acidic catalyst and (4) emulsifier in an aqueous medium until the desired molecular size is reached.

The present invention relates to a process for preparing arylpropenes, especially 1-methoxy-4-(1-propenyl)benzene (anethole), by means of thermolysis of the corresponding 1,1-diarylpropanes.

An object of the present invention is to provide a polyamide resin composition having high mechanical properties and high heat resistance while achieving a satisfactory balance between various physical properties. A molded product made of this polyamide resin exhibits a lower warpage and excellent surface appearance. A method for producing the polyamide, resin composition is also provided. The present invention provides a polyamide resin composition containing a polyamide resin and swelling mica treated with a polyether compound having a bisphenol structure. The present invention also provides a method for making the polyamide resin composition including melt-mixing a polyamide resin with a polyether compound.

A feed pump designed as side-channel pump has a shaft for a rotationally fixed connection to an impeller. Two flattenings are arranged on the shaft so that they are nonparallel to one another. The impeller is thereby mountable on the shaft only in an intended position so that the impeller is rotated in an intended direction of rotation in a casing. The feed pump may therefore be assembled in a particularly simple way.

The disclosure herein relates to the innovative epinephrine formulations in aqueous solution of medicinal products that enhance the physicochemical stabilities of epinephrine and extend the product shelf life. In some instances, the formulations comprise epinephrine or a salt thereof, a complexing agent, and a “non-sulfite” antioxidant. The epinephrine formulations substantially demonstrated the superior physicochemical stabilities to conventional sulfite formulation of commercial medications currently available. In some instances, sulfite-free formulations further provide further benefit (e.g., safety benefits) to sulfite-sensitive patients. The compositions, methods for preparing the formulations, and methods of using the same (e.g., in the treatment of anaphylaxis) are also provided.

The invention relates to resin compositions comprising a) at least one amorphous semi-aromatic polyamide; b) at least two semi-crystalline polyamides, b1) and b2) and c) at least one glass reinforcement agent and shaped articles thereof showing a good balance of properties in terms of good mechanical properties, excellent surface appearance and reduced sink marks.

The current invention reports a method for concentrating an immunoglobulin solution by tangential flow filtration wherein the transmembrane pressure and the cross-flow are variable.

In a method for cutting freeform surfaces, a workpiece is cut by a cutting tool such that a desired freeform surface may be achieved, the cutting tool for cutting purposes being moved along at least one defined cutting path relative to the workpiece. A cutting tool is used, the tool head of which has a greater radius than a tool shank of the cutting tool.

Disclosed is a process for performing a reductive amination of a first functional group in an organic feed substrate, which feed substrate comprises at least one further functional group containing a halogen atom, in the presence of hydrogen, a nitrogen-containing compound, and a catalyst, wherein the presence of the nitrogen-containing compound, expressed in a molar ratio relative to the first functional group in the organic feed substrate, at least during the reaction as long as the conversion of the organic feed substrate has not yet reached 80%, is maintained below a level of 1.3. Further disclosed is a composition of the invention comprising at least 98.0% wt of 2-chloro-benzyl-dimethylamine, at most 0.60% wt of the meso-o-Cl-BDMA dimer and at least 1 ppm wt of the (+ / −)-o-Cl-BDMA dimer and any use therefor.

Disclosed is a formulation and method for treating paper so that paper in landfills produces less methane than untreated paper. The method includes adding one or more nitrate salts to paper during the process of making paper, or after the paper is made. One effect of adding the nitrate salts is promoting the growth of certain bacteria which do not produce methane as they consume paper products.

Process for removal of the amino protective group of a N-acylated {(1S,4R)-4-[2-amino-6-(cyclopropylamino)-9H-purin-9-yl]-cyclopent-2-enyl}methanol of formula (II) where R═H or a (C1-C4)-alkyl, using an inorganic base in a mixture of water and alcohol, to yield abacavir or its salts. The process proceeds very fast and the product can be obtained in high yield and purity.
