  • Patent number: 4686289
    Abstract: New anisotropic compounds with a cross-polarizing substituent have the formula (1) ##STR1## The increase in .epsilon..perp. is achieved by the polarizing group X, preferably the cyano group or a halogen atom, which is not laterally on the ring, as with the known compounds, but is on the bridge, that is to say is part of the main bridge bonding rings A and B to one another. Ring A has the formula (1a) or (1b) given herein and is always cycloaliphatic, while ring B can be identical to ring A or is an aromatic ring of the formula (1c) or (1d) herein. R.sup.1 and R.sup.2 are identical or different end groups of the formula (1e) herein.The radical X on the bridge causes less widening of the molecule than a radical X on a ring, which provides comparatively higher clear points and moreover enables aromatic rings to be omitted from the anisotropic compounds.

  • Patent number: 4471134
    Abstract: A mixture of intermediate products including a carboxylic salt of 3,4,5-trimethoxybenzoic acid (TMB acid) and a dimethoxy benzoic acid derivative of such salt further containing an oxygen anion in the 3,4, or 5 position is prepared by initially reacting hydrolyzable tannin with a methylation agent in an alkaline medium under methylation conditions to form methylated tannin and thereafter hydrolyzing the methylated tanning by reaction thereof with a hydrolysis agent under alkaline hydrolysis conditions. The resulting reaction mixture is then methylated to form a reaction mixture containing methyl 3,4,5-trimethoxybenzoate and a salt of 3,4,5-trimethoxybenzoic acid. TMB acid can be formed in high yield by conversion of both the methyl ester thereof and the salt thereof.
