Abstract
Disclosed is a process for producing mixtures of liquid crystal compounds, wherein at least one of the starting components consists of a mixture of at least two compounds and this mixture is reacted, with at least one other starting component to form a random mixture.
Description
The present invention relates to a kind of method for preparing the mixture of liquid crystalline cpd, wherein at least a starting ingredient contains the mixture of at least two kinds of compounds, this mixture with known method and the reaction of at least a other starting ingredient, is generated a kind of mixture at random.
Liquid crystal material does not have performance required when using during as pure substance usually.Have only different liquid crystalline cpd is mixed, also mix if desired with non-liquid crystalline cpd, the application that just can make the character of liquid crystal material be suitable for being intended to, described character for example is mesomorphic phase temperature, electro-optic response time, double refraction or viscosity.For the application in electrooptics, no matter in nematic phase still in the Application Areas of ferroelectric phase, it is normally necessary to contain the mixture of a large amount of different compounds, usually greatly more than four kinds of compounds.Have the very big liquid crystalline cpd of structural difference, but in many mixtures, the structure of each component is can not difference very big.For example, the mixture of various alkoxyl group cyanobiphenyls, Santosol 360 or phenol benzoate is described, and they are usually only different on the chain length of side chain.Yet, the separately synthetic earlier and purifying of each component in these mixtures, and the mixture with required character only just can make in mixing step subsequently.Many liquid crystal compounds are the mixtures that contain the component of different homologue series, but many components are in fact always arranged from same homologue series.Can adding the non-liquid crystal material of lower molecular weight, to reduce kinetic viscosity also be known.
Therefore, in the known method for preparing liquid crystal compound (for example referring to DE-A2927277, DE-A2636684, DE-A2702598, DE-A2701591, DE-A2747113, DE-A2907332, EP-B14840 and German patent application P4408170.7, P4408171.5 and P4405316.9), each component all must be synthesized respectively, so the synthetic work amount is very big.Particularly, consider and to synthesize all these components that much less the space-time yield of these class methods is very low.
An object of the present invention is to seek a kind of like this novel method for preparing liquid crystal compound, it is fairly simple, have less purification step and synthetic in higher space-time yield is arranged.
We find, and this purpose can realize by the method that the present invention prepares the mixture of liquid crystalline cpd.

The other method that changes liquid crystal compound character is to make random mixture hydrogenation.Hydrogenation can be undertaken by common known method.Hydrogenation is particularly suitable for the aromatic ring structure among the mesomorphic group M is changed into the saturated rings structure.
Beat all is to have now found that there is not the shortcoming of the mixture of conventional preparation by the mixture of the present invention's preparation, even because with regard to purification process, in fact they be equivalent to the purification of simplification compound, particularly in chromatography, in HPLC and MPLC method.
The method that prepare earlier the simplification compound when preparing mixture is compared, the main advantages of the inventive method be simplified synthetic because only need usually prepare single mixture, rather than many single compounds.So space-time yield and solvent-oil ratio significantly descend in the methods of the invention.
The inventive method can also prepare and can not prepare with ordinary method at all, perhaps can only use the mixture of very high expense preparation, because relate to the complexity of the synthetic expense of one-component synthetic ordinary method with mixture, (for example different many starting ingredients) index increases.
On the contrary, the inventive method can be easy to make has the complex mixture of optimizing performance, for example viscosity, time of response, phase scope, double refraction or dielectric anisotropy to application.
