during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
The production of ethylen tially attractive, since the carbon source than petrol bonylation using methyl f used as the catalyst. Met were formed along with of formaldehyde source, r paraformaldehyde, 1,3,5-t The highest yields of met as the source of formalde and limited the rate of ca the highest yields of meth produce these products at methanesulfonic acid is a the reactive intermediates

Nebengruppen, Bioanorganik Koordinationschemie: Der erste Lösung beobachtbare σ-Methankomplex; Rekorde für Magnetisches-Blocking-Temperatur; Titan hilft, Ethyl...
Visible spectrophotometry is used to study the kinetic of ligand exchange in the system Cu(salpn)/H2salen with or without triethylamine (NEt3) and H2O in acetonitrile solvent at 25 ± 0.1°C and 0.01 M NaNO3 (H2salen and H2salpn are N,N'-ethylen-bis(salicylaldimine) and N,N'-propylen-bis(salicylaldimine), respectively). It is found that the reaction rate is first-order with respect to Cu(salpn). ...
nowadays gamete and embryo freezing is an appropriate approach for preserving of genetic traits in laboratory animals, rare and endangered species. frozen cells are suitable replace for actively breeding animals colony. the aim of this study was to perserve laboratory mouse embryo, using vitrification method and comparing effect of two cryoprotectants, glycerol-sucrose(gs) and ethylene glycol-f...
Die Elektroreduktion von CO2 zu Acetat ist eine vielversprechende Strategie zur Speicherung erneuerbarer Energie, jedoch fällt normalerweise als Nebenprodukt an. Pei-Qin Liao und Mitarbeiter berichten in ihrer Zuschrift (e202206470) über ein kovalentes organisches Gerüst mit isolierten aktiven Zentren für die hochselektive Acetat. Das aktive Kupfer-Phthalocyanin-Zentrum hoher Elektronendichte b...
