标 题 :Synthesis of glufosinate using an amidase-based process
发明人：ZIMMERMANN GUNTHER; POTT MORITZ STEFAN
权利人:BASF SE
摘要:The present invention relates to a method of preparing glufosinate, comprising the steps of hydrolysing an N-carbamoyl glufosinate amide with an Amidase enzyme to form an N- carbamoyl amino acid compound followed by cleaving off the carbamoyl moiety of said N- carbamoyl amino acid compound.

摘要:Systems and processes for gas phase-phase synthesis of trisilylamine. One system includes a reactor vessel having a top, bottom, and sidewall having an inner surface. The reactor vessel includes inlets for gaseous reactants, and a gas inlet for an inert gas. In certain reactors the gas inlets are positioned near the top of the reactor vessel and configured to inject the reactant gases in the reactor substantially vertically and downward therefrom. Other reactors are cyclonic-shaped with tangential feeding of the gases. One or more baffles having a peripheral edge and substantially horizontally positioned in the reactor to define a reaction zone above the baffles and a separation zone below the baffles. The baffles are positioned in the reactor vessel such that there is a gap between the baffle peripheral edge and the inner surface of the reactor vessel. Certain systems and processes include mechanical or static mixers.

标题 :Use of methanol loop purge gas for adjustment of hydrogen to carbon monoxide ratio
发明人：PATEL AMIT; LIOU GWO-JANG ABRAHAM
权利人:IHI E & C INTERNAT CORP
摘要:A system and method for producing at least two synthesis gas derived products in which a stoichiometric ratio for synthesis gas above the ratio normally required for a first synthesis gas derived product and below the ratio normally required for a second synthesis gas derived product is selected. The first synthesis gas derived product is produced, and the excess synthesis gas product is directed to production of the second synthesis gas derived product. The second synthesis gas derived product is then produced. The stoichiometric ratio for synthesis gas is chosen such that the excess components makes up for a shortage of components needed for the production of the second synthesis gas derived product.

摘要:An object of the present invention is to identify an enzyme having activity of synthesizing dihydrotentoxin that is a tentoxin precursor and an enzyme having activity of synthesizing tentoxin using dihydrotentoxin as a substrate. The present invention concerns a tentoxin synthesis-related gene encoding a protein comprising the amino acid sequence of SEQ ID NO: 16 and having activity of nonribosomal peptide synthesis of dihydrotentoxin and a tentoxin synthesis-related gene encoding a protein comprising the amino acid sequence of SEQ ID NO: 18 and having activity of converting dihydrotentoxin to tentoxin.
