What is 3-Chloropropyne?
Chemical properties
Light yellow liquid
The Uses of 3-Chloropropyne
Intermediate in organic synthesis.
The Uses of 3-Chloropropyne
Propargyl chloride was used to study emission spectra of dissociating propargyl chloride upon photoexcitation at 199 nm. It was used in the synthesis of novel tetraaryl analog of bisphenol A and triaryl analog of bisphenol A propargyl resins.
General Description
Propargyl chloride is an efficient propargylating agent. It generates propargyl radicals by the pulsed laser photolysis.
Hazard
Flammable, moderate fire risk.
Purification Methods
Purify the chloride by fractional distillation at atmospheric pressure. Note that a possible impurity is propargyl alcohol which has has b 114-115o/~760mm (see above). [Henry Chem Ber 8 398 1875.] HIGHLY TOXIC and FLAMMABLE.[Beilstein 1 IV 960.]
