(US20200255362) The disclosure is directed to a method for recovering products from a fermentation broth. The disclosure relates to the use of extractive distillation and/or dehydration to recover products which have close boiling points, such as ethanol and isopropanol, from a fermentation broth. In an embodiment, the recovery of product is completed in a manner that minimizes stress on the microbial biomass, such that it remains viable, at least in part, and may be recycled and reused in the fermentation process, which may result in increased efficiency in the fermentation process. The extractive distillation vessel and/or dehydration reactor may be used downstream of a distillation vessel. To minimize stress on the microbial biomass the distillation vessel may be under vacuum. The extractive distillation vessel may be used alongside a separation vessel such that the separation vessel is capable of recycling extractive distillation agent.
(US4584311) Imidazole derivatives of general formula (I) and acid addition salts thereof, which are useful as industrial microbicides. (Chemical Structure image '1' not included in text) wherein R represents a linear or branched alkyl group having 6 to 9 carbon atoms.
(US4057413) Piperazine derivatives of the general formula (Chemical Structure image '1' not included in text) in which R1, R2, and R3, independently of one another, are each optionally substituted alkyl, optionally substituted alkenyl, alkynyl, cycloalkyl or aralkyl which is optionally substituted in the aryl part, and N IS 0, 1, 2, 3, OR 4, EXHIBIT POWERFUL PLANT GROWTH-REGULATING PROPERTIES.
(US20150329444) Processes for the disproportionation and isomerization of a C5 hydrocarbon feed using a liquid catalyst comprising an ionic liquid and a carbocation promoter are described. The ionic liquid is unsupported, and the reactions occur at temperatures below about 200° C.
