diphenylacetonitrile uses

Diphenylacetonitrile, also known as benzylcyanide, is a chemical compound with various potential uses and applications, including:

  1. Chemical synthesis: Diphenylacetonitrile can be used as a starting material or intermediate in various chemical synthesis processes. It can serve as a precursor for the synthesis of other compounds, such as pharmaceuticals, dyes, and organic chemicals.
  2. Research and laboratory use: Diphenylacetonitrile is used in scientific research and laboratory studies as a reference compound or standard for analytical purposes. It may be utilized in the identification and characterization of other compounds or for the calibration of analytical instruments.
  3. Organic chemistry reactions: Diphenylacetonitrile can participate in various organic chemistry reactions, such as nucleophilic additions or substitutions, to introduce the diphenylacetonitrile moiety into target molecules.
  4. Insect pheromone synthesis: Diphenylacetonitrile can be used in the synthesis of certain insect pheromones. Pheromones are chemical substances that play a role in communication and behavior among insects, and diphenylacetonitrile may serve as a building block for their production.

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).
