Preparation method of dihydric alcohol unsaturated carboxylate

The invention discloses a preparation method of dihydric alcohol unsaturated carboxylate. The method comprises the following steps: 1, adding thionyl chloride to dihydric alcohol in a dropwise manner, carrying out a reaction after dropwise addition is completed, and washing a material obtained after the reaction with water to obtain dihydric alcohol chloride; and 2, adding unsaturated carboxylic acid to the dihydric alcohol chloride obtained in step 1, adding an alkaline substance, adding a polymerization inhibitor, uniformly stirring above materials, heating the obtained mixture to 80-120DEG C, reacting the heated mixture for 1-24h, and centrifuging the obtained reaction product to remove generated chloride and unsaturated carboxylate in order to obtain dihydric alcohol unsaturated carboxylate. The method has the advantages of simple technology, environmental protection, no generation of wastewater, no use of flammable, combustible or carcinogenic organic solvents, no generation of waste gases, and realization of reduction of corrosion to a reaction device and prolongation of the service life of the device due to no use of strong acidic substances in the reactions.

Polymerizable mesogen compound having improved photoreactive efficiency and polymerizable liquid crystal compositions containing the same

The present invention relates to a polymerizable mesogen compound having improved photo-reaction efficiency by introducing an alpha-thiomethyl acrylate group as a photo-reactive group, and to a polymerizable liquid crystal composition containing the same. The polymerizable mesogen compound of the present invention has improved photo-reaction efficiency at a relatively low energy state by introducing an alpha-thiomethyl acrylate group as a photo-reactive group, retains excellent solubility in a host liquid crystal due to an asymmetric structure thereof, and improves stability of the pretilt angle after photo-crosslinking, and thus can be useful as a polymerizable liquid crystal composition, particularly, a polymerizable liquid crystal composition for a polymer stabilization alignment type liquid crystal display.

Hydroxy functional acrylate and methacrylate monomers prepared via lipase-catalyzed transacylation reactions

Candida antarctica lipase B (CAL-B, Novozyme 435) catalyzes the transacylation of methyl acrylate and methyl methacrylate with diols and triols in 2-methyl-2-butanol at 50 °C. Under the experimental conditions, up to 70 mol% of the acyl donor methyl acrylate was converted. Methyl methacrylate is the less efficient acyl donor (up to 60 mol%) due to the higher sterical hindrance in the enzymatic transacylation. Under the reaction conditions high yields of the mono-acylated products are obtained, which contain minor amounts of bis(meth)acrylates. In addition it was observed that Novozyme 435 catalyzes regioselectively the acylation of the primary hydroxyl groups. In comparison with the chemical catalyzed route no selectivity was observed for unsubstituted diols. For substituted diols more mono-acylated product was formed in the lipase-catalyzed reaction than in the chemical catalyzed reaction.
