diphenylacetonitrile synthesis

Add the 250mL ethyl acetate in 500mL glass there-necked flask, open and stir, add the 150g phenylcarbinol, add sodium methylate 80g, 70 ℃ of stirring reactions 2 hours are down to room temperature, add benzyl cyanide 120ml.Be heated to 110 ℃, distillation reaction 10h.Reaction naturally cools to room temperature after finishing, and adds the extraction of 200ml ethyl acetate and 200ml water, tells lower aqueous layer.The upper strata ethyl acetate layer adds water, and washing once adds anhydrous sodium sulfate drying.Concentrating under reduced pressure is removed ethyl acetate.Then in oily matter, add a small amount of dehydrated alcohol crystallisation by cooling, the crystallized product oven dry.Yield 90%, purity 99.0% (GC).

diphenylacetonitrile uses

Diphenylacetonitrile, also known as benzylidenecyanide, finds versatile applications in various industries. Let’s explore its uses under three main categories:

1. Pharmaceutical Intermediates:

Diphenylacetonitrile serves as a crucial building block in pharmaceutical synthesis, acting as an intermediate for a wide range of drugs and pharmaceutical ingredients. It actively participates in chemical reactions, facilitating the formation of complex molecular structures and enabling the production of innovative medications. Its utility extends from large-scale pharmaceutical manufacturing to research laboratories, where it finds application as a valuable chemical reagent.

2. Flavor and Fragrance Industry:

Due to its distinctive odor, diphenylacetonitrile is highly sought after in the fragrance and flavor industry. It is utilized to impart specific aromas to perfumes, cosmetics, and food products. By incorporating diphenylacetonitrile, manufacturers can create unique and captivating scents, enhancing the sensory experience and attracting consumers.

3. Dye Synthesis and Polymer Additive:

Diphenylacetonitrile plays a significant role in both dye synthesis and polymer modification. In dye production, it is employed in the synthesis of vat dyes and solvent dyes, contributing to the creation of vibrant and long-lasting colors. As a polymer additive, it enhances various properties such as flame retardancy and thermal stability. By incorporating diphenylacetonitrile into polymers, manufacturers can tailor the characteristics of the materials to meet specific requirements.
It’s important to note that the applications of diphenylacetonitrile can vary across different industries and research fields. When working with diphenylacetonitrile or any chemical compound, it is crucial to follow proper handling, storage, and safety protocols to ensure safe and efficient use.
