Few studies have been trying to mitigate the water shortage for electrolysis. Direct saline splitting can produce hydrogen, which, however, faces a serious challenge of handling chlorine byproduct10,11. Some proton/anion exchange membrane electrolyzers can use high humidity vapor feed to the anode;...
This part of GB/T 12009 specifies a method for determination of hydrolysable chlorine in aromatic isocyanates for use in the production of polyurethane by potentiometric titration. This part is applicable to the determination of hydrolysable chlorine in toluenediisocyanate (TDI), 4,4'-diphenyl-methane...
for 48 h, the material was filtered through a vacuum pump and rinsed with deionized water to remove excess acid and chlorine. The remaining precipitate was dried, separated from the filter, and stored in 20 ml glass vials. The δ13C values of the organics separated from the decarbonated ...
Continental arc magmas supply the ore-forming element budget of most globally important porphyry-type ore deposits. However, the processes enabling certain arc segments to preferentially generate giant porphyry deposits remain highly debated. Here we eva
The outlook for oil prices is highly unstable. To assure they have the agility to navigate this, chemical companies need to build new organizational capabilities.
