2.A covalent enzyme-substrate intermediate with saccharide distortion in a mutant T4 lysozyme.
3.a colorless acid formed as an important intermediate in metabolism or fermentation.
4.Also on exhibit are the DF21 intermediate-range ballistic missile and DF11 short-range ballistic missile.
5.The study on an intermediate η~5-EtO_2CC_5H_4 (CO)_3MoHgPh showed that this unexpected reaction proceeded via two steps:condensation and symmetrization.
6.One of three organic compounds with composition C6H4NH2OH, used as photographic developers and dye intermediates.
7.Theoretically, the new synthetic process of NDI was put forward using NDA and methanol as raw material merely, BTC and DMC as semifinished product.
8.Pulse injection of CH3I and CH3OH into the in situ cell resulted in the appearance of some crucial C2 intermediates in the reaction, such as surface acctyl, acetate, ketene and enolate .
9.The detection and identification of the adsorbed species, the reaction inter- mediates on catalyst surface, and the active site of the Cu/ZnO/Al_2O_3 catalyst in the synthesis of methanol from synthetic gas were carried out by means of ESCA, kinetic reactor system and"In-Situ" high temperature high pressure infrared spectrophotmeter cell.
