Abstract:
The present invention relates to a reverse wavelength dispersion compound, a reverse wavelength dispersion composition including the same, and an optically anisotropic body including the same. The reverse wavelength dispersion composition according to the present invention can provide a stronger and more stable reverse wavelength dispersion property, and makes it possible to provide an optically anisotropic body having excellent optical properties.
Abstract:
The invention relates to a process for removing an alkanol impurity from a stream containing a dialkyl carbonate and the alkanol impurity, comprising contacting the stream with an aryl group containing ester and a catalyst to effect reaction of the alkanol impurity with the aryl group containing ester.
Abstract:
A methyl group-containing aromatic compound having a phenolic hydroxyl group protected by a protecting group, is oxidized with oxygen in the presence of a imide compound (e.g. N-hydroxyphthalimide) to provide anaromatic hydroxycarboxylic acid derivative. The protecting group includes, for example, an acyl group.
