Light yellow liquid | [Uses]
Intermediate in organic synthesis. | [General Description]
Propargyl chloride is an efficient propargylating agent. It generates propargyl radicals by the pulsed laser photolysis. | [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.] |
