description	NEW MATERIAL:A 2-phenyl-1,3-dioxane derivative expressed by formula I (formula II is optically active asymmetric carbon; R is 1-18C alkyl; n is 1-10). EXAMPLE:(+)-4'-(2-Methylbutoxycarbonyl)-phenyl-4-(5-n-decyl)-1,3-dioxa n-2-yl) benzoate. USE:Useful as a component of a ferroelectric liquid crystal compositions employed as an electrooptical display material, stable to influences, such as chemical, photochemical effects and electric fields, and capable of regulating liquid crystal temperature ranges and various electrooptical characteristics and providing extremely practical ferroelectric liquid crystal compositions by blending with other ferroelectric liquid crystal systems. PREPARATION:Diethyl malonate expressed by formula III is reacted with a bromoalkane in absolute ethanol using metallic sodium to afford a product, which is then reduced and subsequently esterified with a compound expressed by formula IV, etc., to provide the aimed compound expressed by formula I.
