CLEAR COLOURLESS TO YELLOWISH LIQUID | [Uses]
Intermediate in the preparation of 1,4-Butanediol and tetrahydrofuran. | [General Description]
3,4-Diacetoxy-1-butene (3,4-DAB) is a diacetoxybutene derivative. 1,3-butadiene undergoes oxidative acetoxylation in the presence of palladium-based IMCs (intermetallic compounds) to form 3,4-DAB as one of the product. | [Flammability and Explosibility]
