| Summary: | amine allowing for convenient solvent regeneration of amines allows for higher pH levels in the broth amount of lime. The high pH precipitate protein which and sodium acetate solutions. This thesis extends the animal feed. Through 15 extraction runs, no aqueous phase. The distribution coefficients generally available to convert the concentrated salts into other been concentrated, a variety of techniques are broth was adjusted to pH 11.5 by adding a small butyrate. Amine extraction may be used to selectively butyrate. Compared to competing technologies that can be recycled to the fermentor or collected for concentrating calcium acetate, propionate, and Davison et al., 1966, 1967). Once the acid salts have degradation of the amine was observed. extract undissociated acids from a volatile fatty acid extract water from low-concentration calcium acetate extraction. Prior to extraction, the fermentation fermentation broth to determine whether possible fermentation broth, extracting water with tertiary has a high affinity for water. By raising the Lee (1993) has shown that tertiary amines are able to hics. mixture or single amine for extracting water at 40[]C, mixture was used to extract water from actual previous work to include calcium propionate and products such as ketones, alcohols, and acids. At low remove water from a fermentation broth thus resulting in greater productivity. Specifically, surfactants in the broth interfere with the temperature 20 to 25[]C, the water separates from the temperatures, the low-molecular-weight amine mixture the aliphatic group increases in size. The amine the amine. The distribution coefficients, [] , measure the proposed fermentation temperature (Lee, 1993; the selectivity of concentrating calcium salts in the triethylamine and N,N-diethyl-methylamine in a 1:2 vary as follows: [] thus, there is less selectivity as volumetric mixture are superior to any other examined |
