    Nitroethene (L5): 5.0 g (55 mmol) 2-nitroethanol and 10.4 g (84 mmol) of phthalic acid anhydride were heated at 100 mbar in a distillation apparatus to 140-150 degC, until the solution was clear. Then the bath temperature was increased to 180 degC, while the nitroethene was distilled collected in a receiver (cooled to -30 degC). Yield: 3.6 g of pale yellow liquid (89 % of theory). bp 30-34 degC/110 mbar.
