Production method
Acetylac acid can be produced by pressurized hydrolysis of cotton shells or corn cores after glycoaldehyde (aldehyde residue) or waste potato slag with dilute acid. Add the glycoaldate slag to 10% dilute hydrochloric acid, the curing liquid is 1:1.75, mixed evenly into the hydrolytic pan, 0.2MPa pressure steam cooking 8-10h. Then the hydrolysed dilute is filtered and concentrated to a concentration of about 50%. Decompression distillation is then carried out to collect more than 130 degrees C (2.67 kPa) of fractions to obtain the finished product. Raw material consumption quota: 7000kg/t, hydrochloric acid (fold 100%)1800kg/t. Another method is made by re-arranging and hydrolysis of sugar alcohol. Add 4% hydrochloric acid solution to the reaction pan, stir and heat to 97-100 degrees C, slowly add a mixture of sterol, ethanol, water. Gabi, stirring another 30min. Filtration, filter at 80 degrees C (21.3kPa) decompression concentrated, obtain crude acetylpropyl acid liquid. Then decompression distillation, collection of 160-170 degrees C (2.67 kPa) fractions, and then re-distillation, refined acetylac acid, yield of about 75%.
