CETYLACETYLENE - Introduction
1-OCTADECYNE(1-octadecyne) is a linear alkyne containing 18 carbon atoms. Its chemical formula is CH3(CH2)16C≡CH. The following is a description of some properties, uses, methods and safety information about 1-OCTADECYNE:
Nature:
-The appearance is a colorless liquid with a spicy smell.
-It has good solubility and high solubility in organic solvents.
-Liquid 1-OCTADECYNE is relatively unstable and will slowly polymerize into polyacetylene in the air.
Use:
- 1-OCTADECYNE can be used as an important intermediate in organic synthesis, used in the synthesis of a variety of organic compounds and polymer materials.
-It can be used to prepare organic compounds with other functional groups, such as aldehydes, ketones, acids or amines.
Method:
- 1-OCTADECYNE can be synthesized by the termination reaction method, that is, through the common rail alkynylation reaction of appropriate reactants.
-A typical preparation method is to react bromooctane with excess sodium cyanide to produce bromooctyl nitrile, and then convert the nitrile into alkyne through the Goldberg reaction.
Safety Information:
- 1-OCTADECYNE is irritating to the skin and may cause skin sensitivity or inflammation.
-Avoid inhaling vapors or dust when exposed, and wear personal protective equipment such as gloves, goggles and protective masks when necessary.
-Store it in a closed container when storing, avoid contact with oxygen or combustibles, because it is flammable.
-When using and handling 1-OCTADECYNE, you should follow the safety operation procedures and read the relevant safety data form.
