1,3-Acetonedicarboxylic acid CAS 542-05-2
|Product Name||1,3-Acetonedicarboxylic acid|
|Other Name||1,3-Acetonedicarboxylic acid|
It is made by deformicating in the presence of concentrated sulfuric acid with citric acid as raw material. In the industrial process, first put fuming sulfuric acid in the reaction tank, and add citric acid in batches under stirring when it is cooled to below 50°C. The weight ratio is citric acid: fuming sulfuric acid 1:2.34. After the feeding is completed, the temperature is increased to 40-45°C, and the temperature is kept for 3 hours, then the temperature is lowered to 10°C or less, and normal water (insulated below 40°C) is added dropwise, then cooled At about 15°C, centrifuge, rinse with ice water, and spin dry to obtain the finished product.
