1-Etynyl-2-Methoxy-Benzene - Introduction
The chemical formula is C9H8O, also known as phenyl ethynyl ether. The following is a description of the properties, uses, preparation and safety information of the compound:
1. nature:
-Appearance: colorless liquid.
-Solubility: Soluble in organic solvents such as ethanol, ether and acetone, insoluble in water.
-Melting point and boiling point: The melting point is about -30°C, and the boiling point is about 182-185°C.
2. use:
-is useful as a reagent and intermediate in organic synthesis.
-It can be used as a chiral inducer for linear oligomeric polymers.
3. preparation method:
-or can be obtained by the reaction of anisole with 2-chloroacetylene. First, anisole is reacted with an alkali metal base (e. g., sodium hydroxide) under alkaline conditions to produce a benzyl alcohol anion. Then, the resulting benzyl alcohol negative ion is reacted with 2-chloroacetylene to de-chloridiate and form a phenyl anion.
4. Safety Information:
-May be irritating and corrosive to eyes and skin.
-Wear appropriate protective gloves, protective goggles and face mask when using or handling.
-Avoid contact with skin and eyes, and make sure to use in a well-ventilated area.
-When storing and handling, please follow the safety procedures and keep away from fire and heat sources.
Please note that the use and handling of chemicals requires care and care, preferably under the guidance of a professional.
