    摘要: New anisotropic compounds suitable for use in LC-display devices are disclosed and claimed. The new compounds are cyclohexyl cyclohexylmethyl ethers of formula (1): ##STR1## in which X and Y are respectively hydrogen, alkyl group with 1 to 12 C-atoms, alkoxy group with 1 to 12 C-atoms, monoalkylamino group with 1 to 12 C-atoms, nitrile group, nitro group, halogen, or cyclic radical of formula (1a) or (1b): ##STR2## in which R.sup.1 and R.sup.2 represent hydrogen alkyl group with 1 to 12 C-atoms, alkoxy group with 1 to 12 C-atoms, monoalkylamino group with 1 to 12 C-atoms, nitrile group, nitro group or halogen, and Z.sup.1 and Z.sup.2 represent simple covalent bonds or grounds of the formulas --COO--, --OOC--, --CH.sub.2 O-- or --OCH.sub.2, with the requirement that only one of the groups X, Y can be a cyclicradical or formula (1a) or (1b). Also disclosed and claimed are LC-mixtures containing these compounds and methods for their synthesis.

    摘要: The invention relates to a new a method for simultaneous recovering vanadium, molybdenum and gallium from alumina factory aluminate liquors. The recovering is carried out in one step by electrolyzing an alumina factory aluminate liquor a temperature exceeding 70.degree. C. with a current density of from 400 to 1200 A/m.sup.2 using a low-melting liquid alloy as a cathode and agitating said alloy mechanically.By using the new process the three precious metals can be recovered simultaneously in one step with good efficiencies without any preliminary treating of the aluminate liquor and without using any auxiliary chemical.
