adding-alkali aeration method
- The methanol rectification process was introduced and the process of adding alkali or not was compared.
- Corrosion and scale inhibitions of PESA are evaluated by rotary coupon test and aeration method,respectively.
- The results show that using 75% ethanol to extract lappaconitine gets over the problem which was brought by adding alkali traditionally.
- As compared with the present technology at home and abroad, the technological process need not add alkali to conduct a saponified reaction progress.
- The practice was done according to different process of BAF in different aeration methods and filter diameters, the practice showed be feasible.
