The research investigates the synthesis of ethyl benzoate through the ozonolysis of styrene in the presence of ethanol. The purpose of this study is to explore a potentially industrial method for producing ethyl benzoate, a compound with applications in various sectors including dyes, lubricants, herbicides, and cosmetics. The process involves the ozonolysis of styrene, which is then thermally decomposed to yield ethyl benzoate. The study concludes that the method is commercially feasible, with a maximum yield of available oxygen achieved at a molar ratio of styrene to ethanol of 1:1.5. Key chemicals used in the process include styrene, ethanol, ozone, and various intermediates such as molozonide, bipolar ions, and carbonyl compounds. The final products were ethyl benzoate, ethyl formate, formaldehyde, benzaldehyde, formic acid, and benzoic acid.

The research focuses on the synthesis and properties of liquid-crystalline (LC) molecules with unconventional shapes, specifically bowl-shaped and dumbbell-shaped mesogens based on triarylmethyl moieties. The study explores the formation of columnar and micellar cubic liquid-crystalline phases using these mesogens. The bowl-shaped molecules contain one triarylmethyl moiety, while the dumbbell-shaped molecules consist of two triarylmethyl moieties connected by rigid rods. The research investigates the effects of structural bulkiness and polarity on the LC properties of these molecules. Key chemicals involved in the synthesis include tris(4-hydroxyphenyl)methane, tris(4-hydroxyphenyl)ethane, 3,4,5-tridodecyloxybenzyl chloride, and various aromatic compounds such as ethyl benzoate, methyl isonicotinate, and 1,4-phenyldiboronic acid. The study also examines the photoluminescence properties of a specific dumbbell-shaped molecule containing a terphenyl moiety, which shows aggregated structures in the cubic phase. The research aims to develop new building blocks for liquid-crystalline materials with potential applications in various fields such as electrooptics, photonics, and sensory devices.
