FIELD: industrial organic synthesis.
SUBSTANCE: tert-butylacetylene is obtained via reaction of tert-butyl alcohol with acetylene in presence of acid catalyst, content of water in liquid reaction mixture ranging from 10 to 50%. Catalyst is selected from sulfuric, phosphoric, trifluoroacetic acid, sulfonic acids, sulfonate cations, and the like.
EFFECT: increased selectivity of formation of desired compound and increased yield thereof at substantially reduced cost.
