| titleOfInvention | Process for the preparation of a liquid crystal composition |
| abstract | A process for producing a liquid crystal composition in a liquid crystalline state, comprising Performing agitation or ultrasonic irradiation of two or more liquid crystal compounds without using an organic solvent, thereby obtaining a liquid crystal composition in a liquid crystal state, wherein at least one of the liquid crystal compounds has a melting point higher than 40 ° C; the temperature at the start of the agitation or the ultrasonic irradiation is not higher than 40 ° C; the temperature during production after the start of the agitation or the ultrasonic irradiation is not lower than 15 ° C and not higher than 50 ° C; and the liquid crystal compounds are represented by the following general formula (I): wherein R 1 and R 2 each independently represent an alkyl group having 1 to 16 carbon atoms, an alkoxyl group having 1 to 16 carbon atoms, an alkenyl group having 2 to 16 carbon atoms or an alkenyloxy group having 3 to 16 carbon atoms which may be substituted with fluorine, A, B and C are each independently a 1,4-phenylene group, 2- or 3-fluoro-1,4-phenylene group, 2,3-difluoro-1,4-phenylene group, 3,5-difluoro 1,4-phenylene group, 2- or 3-chloro-1,4-phenylene group, 2,3-dichloro-1,4-phenylene group, 3,5-dichloro-1,4-phenylene Group, 2-methyl-1,4-phenylene group, 3-methyl-1,4-phenylene group, naphthalene-2,6-diyl group, phenanthrene-2,7-diyl group, fluorene-2, 7-diyl group, trans-1,4-cyclohexylene group, 1,2,3,4-tetrahydronaphthalene-2,6-diyl group, decahydronaphthalene-2,6-diyl group, trans-1,3- Dioxane-2,5-diyl group, pyridine-2,5-diyl group, pyrimidine-2,5-diyl group, pyrazine-2,5-diyl group or pyridazine-2,5-diyl group where these groups can be substituted by 1 to 3 fluorine atoms, m represents 0, 1 or 2, Each of Z 1 and Z 2 is independently a single bond, -CH 2 CH 2 -, - (CH 2 ) 4 -, -OCH 2 -, -CH 2 O-, -COO-, -CH = CH-, -CF = CF -, - CH = NN = CH- or -C = C-, and when m is 2, the two Z 2 and C groups may be the same or different. |
