The profound success of reactive extraction has been noted in the recovery of carboxylic acids from dilute solutions. In present paper, equilibrium of caproic acid with aliquat-336, a quaternary amine compound, in xylene and Methyl Isobutyl Ketone (MIBK) has been studied. Equilibrium parameters such as distribution coefficients, loading ratio, degree of extraction and equilibrium complexation constants have been presented. The data obtained is useful in understanding the equilibrium characteristics and efficient design of the recovery process of caproic acid by reactive extraction.展开更多
浓香型白酒的主体香味物质是己酸乙酯,己酸菌是重要的功能菌种。该研究从优质窖泥中分离获得了高产己酸菌株,命名为JZZ,该菌是革兰氏阳性杆菌,经形态学和16S r DNA序列鉴定,属于克氏梭菌(Clostridium kluyveri)。通过培养条件考察,该己...浓香型白酒的主体香味物质是己酸乙酯,己酸菌是重要的功能菌种。该研究从优质窖泥中分离获得了高产己酸菌株,命名为JZZ,该菌是革兰氏阳性杆菌,经形态学和16S r DNA序列鉴定,属于克氏梭菌(Clostridium kluyveri)。通过培养条件考察,该己酸菌最适培养条件为接种量5%,装样量90%,培养温度37℃,p H值为6.5。在最适培养条件下,菌株JZZ的己酸产量均可达到4.36 mg/m L。展开更多
文摘The recovery of caproic acid from the aqueous stream is of practical relevance due to its market value and the stringent environmental standards.
