Embodiment 1
[0046] Put 200 g of acetyl chloride to be treated at one time into a 500 ml four-neck flask equipped with devices such as a thermometer, mechanical stirring, reflux condenser, and constant pressure dropping funnel. After feeding, the three-necked flask was immersed in cooling water and started stirring. Add 0.2g of concentrated sulfuric acid with a mass fraction not lower than 98% into a constant pressure dropping funnel and drop it into acetyl chloride at a constant speed. The temperature during the dropping process is not higher than 45°C, and the dropping time is 0.5-1h. After the concentrated sulfuric acid was added dropwise, the cooling water was removed and replaced with an electric heating mantle, and the constant pressure dropping funnel was removed and replaced with a sealing plug. Acetyl chloride was slowly warmed up to full reflux, and the reflux reaction time was 1 hour. After the reflux reaction is completed, the reflux device is changed to a rectification device...
Embodiment 2
[0048] The operation steps of the present embodiment are basically the same as those of the embodiment 1, the difference is as follows: the mass fraction of dripping is not less than 0.8 g of 98% concentrated sulfuric acid.
Embodiment 3
[0050] The operating steps of this embodiment are basically the same as those of Embodiment 1, except that the mass fraction of the dropwise added concentrated sulfuric acid is not less than 0.1 g of 98%.
