Synthesis of acyloin natural products by Mukaiyama hydration
Organic & Biomolecular Chemistry, 2022The preparation of Co(ii) and Co(iii) SALPN type catalysts for the Mukaiyama hydration of enones, and their application to the synthesis of acyloin natural products is described. An acyloin rearrangement was key to the success of this approach.

SPE/IATMI Asia Pacific Oil & Gas Conference and Exhibition, 2021
Abstract In recent decades, the development of natural gas hydrates has become a research hotspot of scholars all over the world. However, the decomposed gas and water in marine gas hydrate production system may regenerate gas hydrates due to the low-temperature and high-pressure environment in seafloor.

Clathrate Hydrates for Production of Potable Water
MRS Proceedings, 2006ABSTRACTClathrate hydrates are crystalline inclusion compounds of water and a guest molecule (e.g., methane) that form at temperatures below ambient but above the freezing point of water. There are three known crystalline structures of hydrates (structure I, II, and H) in which cavities within the hydrogen bonded water molecule lattice trap the hydrate-

Hydrate Mitigation in a Deepwater Production System
SPE Offshore Europe, 1989Abstract Deepwater developments such as the one depicted in Fig 1 rely on production flowlines to carry raw, unprocessed reservoir fluid, called full wellstream (FWS) production, from wells to production facilities. As the search for reserves has taken the petroleum industry into deeper water and colder environments, the feasibility of ...

Hydration products of calcium aluminoferrite
Cement and Concrete Research, 1983Abstract Hydration products of Ca2AlFeO5, steam cured at 72 C, have been identified using X-ray diffraction and Mossbauer spectroscopy. Iron-bearing phases are hydrogarnet Ca3FeyAl2−y(OH)12 with y = 0.22, and non-crystalline ferrihydrite Fe(OH)3.nH2O.

Metakaolin—lime hydration products
Thermochimica Acta, 1984Abstract Four mixtures were prepared of weight ratios 80:20, 70:30, 60:40 and 50:50 of china kaolin/pure Ca(OH) 2 . Each mix was activated for 2 h at 800°C and then paste hydrated at room temperature and 100% RH for up to 28 days. The hydration products were studied by XRD as well as DTA and TG techniques.

Hydrated Electron: Production and Role in Photobiology
Science, 1963Many inorganic anions in aqueous solution either yield the hydrated electron on photolysis or they are strong scavengers. In neutral solution the hydrated electron is a primary photochemical product of aromatic amino acids.
