Reaktionsschritte

A mixture of 137 g (1 mole) of o-nitrotoluene, 120 g of paraformaldehyde, 34 g of potassium hydroxide and 500 ml of dimethyl formamide containing 0.7% by weight of water is stirred at 30° C. for 1.5 hours and then at 55° C. for 1 hour. The reaction mixture is processed as described in Example 1 to obtain 35 g of o-nitrophenylethanol, 20 g of o-nitrotoluene and 35 g of bis-methylol compounds. The bis-methylol compounds were identified by gas chromatographical mass spectrum (GCMS) analysis.
