3-Chloropropyne Usage And Synthesis

Chemical Properties	Light yellow liquid
Uses	Intermediate in organic synthesis.
Uses	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.]
