Product Properties:
1.Similar to butyl acetate. Decomposes to 1-butene, 2-butene, ethylene and propylene when heated to 500 °C. When sec-butyl acetate is passed through glass wool in a stream of nitrogen at 460 to 473°C, 56% 1-butene, 43% 2-butene and 1% propylene are produced. When heated to 380°C in the presence of thorium oxide, it decomposes into hydrogen, carbon dioxide, butene, sec-butanol and acetone. The rate of hydrolysis of sec-butyl acetate is small. When ammonolysis occurs in dilute alcoholic solution at room temperature, 20% is converted to amide in 120 hours. It reacts with benzene in the presence of boron trifluoride to form sec-butylbenzene. When photo-chlorination is carried out, chlorobutyl acetate is formed. Among them, 1-methyl-2 chloropropyl acetate accounts for 66% and other isomers account for 34%.
