Key points for the process
- TOA has high extractability and used for selective removal of contaminated organic acids and salts from dilute fermentation broth
--Only extract the undissociated form of carboxylic acids
-- Need multistage extraction using different degrees of dissociation of each acid with pH - Vacuum distillation
--Concentrate the pretreated broth and remove volatile organic acids such as acetic acid, formic acid etc. - Crystallization
--The crystal of SA is formed more than other organic acids in saturated fermentation broth (after vacuum distillation) and low solubility
Any comments for this method? Advantages and disadvantages? Cost or simplexity?

nice article and topic your blog, this some solve to reduce about global warming.
Thanks for your comments and encouraging. I will blog more about sugar-based chemicals and related issues.
