标题:Synthesis of polyether polyols based low dosage gas hydrate inhibitors using double metal cyanide catalyst

摘要:A series of different metals (Zn/Fe/Co/Sn/Mg/La/Al/Cr) based double metal cyanide (DMC) catalyst is disclosed herein. Benzene-1,3,5-tricarboxylic acid (BTC) is incorporated as an organic complexing agent (CA) in the DMC catalyst. The DMC catalysts prepared with BTC and its derivatives as CAs are highly active towards ring opening polymerization (ROP) of propylene oxide (PO) and imparts heterogeneity as compared to the DMC prepared without any CA. The polyether polyols (PEPOs) with controlled molecular weight (Mw), polydispersity index (PDI), hydroxyl value (OH), and iodine value (I2) are produced using a DMC catalyst. PEPOs of the present invention relate to low-dosage gas hydrate inhibitors (LDHIs) utilized to mitigate/manage the formation, growth, and deposition/agglomeration of gas hydrate crystals in oil and gas production pipelines (especially applicable to deep and ultra-deep developments), and drilling or fracturing operations during natural gas hydrate exploration.

标 题:Process for preparing acetaldehyde from methanol and synthesis gas using a novel catalyst composition
发明人：LIN JIANG-JEN; KNIFTON JOHN F
权利人:TEXACO INC
摘要:Acetaldehyde is prepared in good yield from methanol and synthesis gas under mild reaction conditions by contacting a mixture of methanol, carbon monoxide and hydrogen with an iodide or iodine free catalyst composition comprising (1) ruthenium powder, (2) a cobalt-containing compound (3) a rhodium-containing compound, and (4) an onium salt or base, and heating the resulting mixture under mild temperature and pressure for sufficient time to produce the desired acetaldehyde, and then recovering the same from the reaction mixture.

摘要:A double metal cyanide [DMC] catalyst and a method for the synthesis thereof at room temperature is disclosed herein. Various Schiff bases are incorporated as organic complexing agents in the DMC catalysts. The catalysts of the present invention are highly active for the ring opening polymerization (ROP) of epoxides in the presence of different H-functional initiators to produce polyether polyols (PEPO) with a wide range of average molecular weight (Mw) and polydispersity index (PDI).
