Übersetzung für "Phenyl salicylate" in Deutsch

The incorporation of UV absorbents, such as phenyl salicylate, is also customary.

B and B' can be for example phenyl, naphthyl or one of the aromatic 5- or 6-membered heterocyclic structures mentioned for G, or a derivative of benzophenone, benzothiazole, benzotriazole, quinoxaline, triazine, phenyl salicylate, 2,4-dihydroxyphenyl or pyrone, which are all considered suitable for use as radical B or B', having very high absorption in the ultraviolet spectrum.

As the acaricidal active substance (component A below), high-boiling esters can be used, in particular benzyl benzoate, benzyl salicylate, phenyl benzoate, phenyl salicylate as well as mixed and simple phthalates such as, for example, dimethyl phthalate, diethyl phthalate, dibutyl phthalate, dioctyl phthalate, diisodecyl phthalate, diallyl phthalate or benzyl butyl phthalate.

The list of cosmetic products below is a selection of the most requested cosmetics that contain the ingredient Phenyl Salicylate.

Although the process described enables diaryl carbonates to be freed very substantially of high boilers, for example phenyl salicylate, nowhere is the presence of troublesome catalyst residues or intermediate boilers or a means for their removal described.

Especially the presence of significant amounts of catalyst residues can, however, influence a distillative purification, since this accelerates the side reaction of diaryl carbonate to give phenyl salicylate and hence promotes the enrichment thereof in the bottom of the column.

In the case of the industrially important synthesis of polycarbonates from BPA and DPC, the vapor streams contain, in addition to phenol, secondary components such as DPC, BPA, low molecular oligomers from BPA and DPC phenyl salicylate, isopropenylphenol and dimers and oligomers thereof, hydroxyindanes, hydroxychromanes, catalyst residues and secondary products thereof.

In principle, separation of the aforementioned secondary components, such as isopropenylphenol, phenyl salicylate or hydroxyindanes, from the polycarbonate melt via the gas phase is desirable, since a higher purity of the polycarbonate obtained would be achieved by the removal of these components.

Suitable UV absorbers are 2-hydroxy-4-n-octoxybenzophenone, 2-hydroxy-4-methoxybenzophenone, 2-(2'-hydroxy-5'-methylphenyl)benzotriazole, as well as other derivatives of 2-hydroxybenzophenone, or of benzotriazole, also 2,4-dihydroxybenzoylfuran, phenyl salicylate, resorcinol disalicylate, resorcinol monobenzoate and dibenzoate, benzyl benzoate, stilbene, ?-methylumbelliferone, and its benzoate Numerous other UV absorbers are known and available on the market.

What is claimed is: A cholesteric liquid-crystalline polymer which in the molecule comprises at least one stabilizer comonomer selected from the group consisting of o-hydroxybenzophenone, 2-(o-hydroxyphenyl)-benztriazole, phenyl salicylate, a sterically hindered phenol, a sterically hindered amine, a phisphine, a phosphite, a phosphonite a thiocarboxylic ester, an alkyl sulfide, or a combination thereof.

Examples of light stabilisers include phenyl salicylates, benztriazole and derivatives thereof, HALS compounds, and oxalanilide derivatives.

Furthermore, small amounts of light stabilizers, such as, for example, benzophenone derivatives, benzotriazole derivatives or phenyl salicylates, can be added.

It is also possible to add small amounts of light stabilizers, such as, for example, benzophenone derivatives, benzotriazole derivatives, tetraalkylpiperidines or phenyl salicylates.

Not only component (A), but also in particular component (B) can additionally also be used in a mixture with pigments which are unreactive per se or little reactive or with further auxiliaries such as silica gel or UV absorbers, for example 2-(2'-hydroxyphenyl)benzotriazoles, benzophenones, cyanoacrylates, phenyl salicylates.

The developers can additionally also be used in a mixture with pigments which are unreactive per se or slightly reactive or further auxiliaries such as silica gel or light stabilizers, for example 2-(2'-hydroxyphenyl)benzotriazoles, benzophenones, cyanoacrylates, phenyl salicylates.

The developers may also be used in admixture with basically inert or almost inert pigment or other modifiers such as silica gel or UV absorbers such as 2-(2'-hydroxyphenyl)benzotriazoles, benzophenones, cyanoacrylates, or phenyl salicylates.

The developers can additionally also be used in a mixture with pigments which are unreactive per se or little reactive or further auxiliaries such as silica gel or light stabilizers, for example 2-(2'-hydroxyphenyl)benzotriazoles, benzophenones, cyanoacrylates, phenyl salicylates.

The present invention therefore provides cholesteric liquid-crystalline polymers which in the molecule comprise at least one stabilizer comonomer from the group consisting of UV absorbers, such as o-hydroxybenzophenones, 2-(o-hydroxyphenyl)benzotriazoles and phenyl salicylates, for example, or from the group of antioxidants, such as sterically hindered phenols, sterically hindered amines, phosphines, phosphites, phosphonites, thiocarboxylic esters and alkyl sulfides, for example.

In addition, small amounts of light stabilizers such as, for example, benzophenone derivatives, benzotriazole derivatives, tetraalkylpiperidines or phenyl salicylates, can be added.

It is also possible to add small quantities of light stabilizers, such as, for example, benzophenone derivatives, benzotriazole derivatives, tetraalkylpiperidines or phenyl salicylates.
