3-Hexyn-2,5-diol Usage And Synthesis
Description
3-Hexyne-2,5-diol is a more or less solid yellow mass of crystals depending on the relative content of the meso form. It is miscible with water and polar solvents. 3-Hexyne-2,5-diol is produced by BASF from acetylene and acetaldehyde by the Reppe ethynylation method.
Uses
3-Hexyne-2,5-diol is used in the synthesis of hyperbrancehed poly([1,2,3]-triazoles. Also used in the synthesis of pyrazoles and thiopyrazoles.
Application
3-Hexyne-2,5-diol is used in nickel process baths as a brightener. It is the starting material for production of pyrroles and of 2,5-hexanediol, as well as in the production of 4-hydroxy-2,5-dimethyl-3-(2H)-furanone, trade name Furaneol, used as pineapple and strawberry flflavor.
Flammability and Explosibility
Non flammable
