Übersetzung für "Oxidativer abbau" in Englisch

Oxidative degradation of the starch is preferred.

Under strongly alkaline conditions, some oxidative degradation may occur.

After removal of volatile constituents by distillation, it is naturally possible to subject the noble metal/carbonyl-complex to oxidative degradation but this would entail the destruction of the entire quantity of organic promoters whereby the beneficial effect which is associated with catalyst work up would be jeopardized from the onset.

This is all the more unexpected since it is known per se that polyphenylene oxide (PPO) has only a very low water absorption capacity, yet at higher temperatures an oxidative destruction is nevertheless ascertainable.

This after-purification can comprise first carrying out oxidation degradation by addition of suitable oxidizing agents, such as hydrogen peroxide and/or ozone (both also in combination with UV light) and if appropriate following this with a biological treatment.

After removal of volatile constituents by distillation, it would naturally be possible to subject the noble metal carbonyl-complex to oxidative degradation but this would simultaneously entail the destruction of the entire quantity of organic promoters whereby the beneficial effect which is associated with catalyst work up would be jeopardized from the onset.

In this case, side reactions such as oxidation of the phenol ring or oxidative degradation of the 2-isoxazoline ring can be avoided by appropriate conduct of the reaction at a low temperature.

Oxidizing acids such as HNO3 are used particularly in cases when an oxidative degradation of the employed natural substance is desired.

Accordingly, it is an object of the invention to provide a process for conditioning organic substrate surfaces, which avoids oxidative degradation and fragmentation reactions and improves the prerequisite properties for carrying out subsequent treatment processes.

Whereas mouldings composed of pure swellable graphite are destroyed at 700° C. in a very short time by oxidation in air, no essential oxidative degradation (determined gravimetrically or mechanically for example) can be detected even after hours when, for example, 20% to 45% by weight of intumescence media according to the invention are present.

The great advantage of TPE over vulcanized elastomers lies in its substantially simpler processing which eliminates mastication (oxidative degradation), the admixture of vulcanization accelerators, and in some cases even the compounding, and also, of course, vulcanization.

However, the same whiteness of at least 89.5% ISO (according to PAPTAC standard E.1) and the same stability of the whiteness must be achieved as with the bleaching sequence O-D 0 -E OP -D 1 -P, and there must be no greater oxidative degradation of the chemical pulp.

Through this mode of addition it is possible, surprisingly, to achieve a considerably greater oxidative breakdown of the dye in the wash liquor on industrial implementation than is possible with the process of WO-A 99/34054 in which the enzyme, the mediator, and the peroxide compound are added individually and simultaneously to the rinsing liquor.

CN 1749278 A proceeds from vegetable fibres which are subjected to alkaline digestion, oxidative bleaching and degradation with aqueous sodium hydroxide solution and chlorine gas and also subsequent intensive ultrasonic treatment to obtain a gel which contains spherical particles of cellulose 10-20 nm in size.

By the material undergoing all the processing steps or being pretreated or prepared and/or transferred and/or injected in a vacuum or a protective gas, it can be prevented from decomposing by oxidation or hydrolysis.

In addition, a so-called “flash oxidation” takes place in the lime elimination unit 130 a in which metabolic end products of the microorganisms formed in the anaerobic reactor 125 a are oxidized by the supplied dissolved air or by air oversaturation, whereby an additional oxidative degradation of the impurities and/or disturbing materials contained in the process water takes place and an odor emission is largely reduced.

But the mixtures obtained have insufficient stability against oxidative degradation.

Nicotinic acid was first synthesized in 1867 by oxidative degradation of nicotine.

The invention relates to a phosphite-free lubricating oil composition highly resistant to oxidative degradation.

The present invention relates to lubricant compositions which are stabilized against oxidative degradation.

Additives against oxidative degradation of the lubricants, the so-called antioxidants, are of particular importance.

Acetic acid is to be preferred because of its higher resistance towards oxidative degradation.

During this reaction, the graft base may even undergo oxidative degradation.

These antioxidants prevent a degradation of the dyes by oxidation.

The invention relates to lubricant formulations that are stabilised against oxidative degradation.

Processes for the oxidative degradation of polyethylene plastic are known.

The substance is thereby subject to relatively severe oxidative degradation.

After the first extrusion with oxidative degradation the product has the following molecular data:

The oxidizing decomposition of organic water loading materials is increased by ozone.

The mixture imparts a high stability towards oxidative degradation to lubricant compositions.

A sample taken after this time again shows no oxidative degradation whatsoever.

This prevents any hydrolytic and oxidative decomposition of the melt in the extruder.

The antioxidant is used to increase the stability of the active ingredient to oxidative breakdown.

The oxidative decomposition of high-viscosity cellulose ethers can be carried out after the cleaning process.

In addition, the reduced oxidative degradation increases the stability of the colorants employed.

Requirements for color values allow no oxidative or thermal degradation.

Oxidative degradation of the morpholinone moiety and hydrolysis of the amide bonds are the major sites of biotransformation.
