Two different new calamitic liquid crystals (LCs), 4-[4-(((S)-3,7-dimethyloctyloxy)phenoxy)carbonyl]phenyl 4-(n-decyloxy)benzoate (DPDEB) and 4-[4-(((S)-3,7-dimethyloctyloxy)phenoxy)carbonyl]phenyl 4-(n-dodecyloxy)benzoate (DPDOB) were synthesized and characterized using 1H-NMR, and 13C-NMR. The LC behavior of the target compounds was investigated by optical polarization microscopy (PM) and differential scanning calorimetry (DSC). The selectivity coefficients, a, of the structural isomers at infinite dilution for the DPDEB and DPDOB LCs were determined for Bu acetate, Bu alc. and amyl alc. isomers. Surface energy anal. has been performed using inverse gas chromatog. (IGC). By using suitable solvents, the surface properties and separation power of isomers of DPDEB and DPDOB LCs were determined between 303.2 and 323.2 K. Experiments with LC’s have been conducted at infinite dilution to the specific adsorption enthalpy and the specific adsorption free energy. IGC measurements exhibited values of acidity constants (KA) of 0.033 and 0.057 and basic constants (KD) of 0.176 and 0.242 for DPDEB and DPDOB, resp. It has been found that all LCs show basic character. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Quality Control of 4-Benzyloxyphenol).
4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Quality Control of 4-Benzyloxyphenol
