PROBLEM TO BE SOLVED: To provide a production method capable of obtaining a high-purity benzyl ether compound at excellent yield by a simple method. SOLUTION: This invention relates to a method for producing a benzyl ether compound represented by general formula (In the formula, R1-R3each represents a hydrogen atom, a 1-3C alkyl group, or a 1-3C alkoxy group, and R4represents a 1-3C alkyl group) which is obtained by reacting a benzyl alcohol compound having a phenol group with an aliphatic alcohol compound in the presence of an inorganic acid and a nitro compound.

Homologation d'hydroxymethyl anthraquinones

, p. 901 - 904 (2007/10/02)
2-Hydroxymethyl anthraquinones (Aq-CH2OH) bearing at least one phenolic group in the ortho position (C-1) afford in presence of triethyl orthoacetate and of a catalytic amount of p-toluenesulfonic acid, homologous esters of type Aq-CH2-CH2COOEt. 2-Hydroxy benzyl alcohol behaves similarly while 4-hydroxy benzyl alcohol gives only the corresponding benzyl ether.In situ, formation of both a protonated quinone methide from Aq-CH2OH and of diethoxy-1,1 ethene from triethyl orthoacetate followed by concerted or step-wise condensation accounts for the formation of the observed esters Aq-CH2-CH2COOEt.

The homologous series of 4-alkoxymethylene-substituted-phenyl 4'-alkylcyclohexanecarboxylates are prepared.And their transition temperatures, bulk viscosities and birefringences have been measured comparing with the series of 4-alkoxy-substituted-phenyl 4'-alkylcyclohexanecarboxylates.The differences between the alkoxymethylene-substituted series and alkoxy-substituted series are discussed.Alkoxymethylene groups contribute to lowering the transition temperatures, and also reducing the bulk viscosities and optical anisotropy compared to the alkoxy groups as terminal groups of mesogens.This is apparently due to the higher flexibility of the alkoxymethylene groups, which affected the packing of molecules.
STUDY OF NEW LIQUID CRYSTAL MATERIALS (II): SYNTHESIS AND MESOMORPHIC PROPERTIES OF ALKOXYMETHYLENE SUBSTITUTED PHENYL CYCLOHEXANECARBOXYLATES.

The properties of alkoxymethylene-substituted-phenyl alkylcyclohexanecarboxylates are described. Such phenyl cyclohexanecarboxylates exhibit either a monotropic or an enantiotropic nematic phase. Their clearing points were lower than those of alkoxy-substituted-phenyl alkylcyclohexanecarboxylates, an effect considered to be due to the flexibility of the alkoxymethylene groups.
