Sodium dithionite, 60 mM in UGM reaction buffer E. coli UGM, 1.1 μM in UGM reaction buffer The 2.0 mM stock solution of UDP-Galf was prepared by dissolving UDP-Galf (1.22 mg/mL) in UGM reaction buffer. The exact concentration was calibrated by HPLC (Varian Microsorb 100-5 C18, 4.6 ...
After completion of the reaction the solution is passed through a filter press to remove unreacted zinc; dust and impurities from the zinc;. The zinc; is then precipitated from the zinc dithionite; by adding sodium carbonate; or sodium hydroxide; in stirred vessels. The zinc carbonate; or ...
Sodium dithioniteConjugated dienoic acids1,4-AdductsThe reaction of fluorine-containing halides and acetamides with conjugated dienoic acids initiated by sodium dithionite gave halide-free 1,4-adducts in 40–80% yields, with the E configuration as the major products....
Additional gas-generating reactions occur with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), and even carbonates: the carbon dioxide gas from the last is nontoxic but the heat and spattering from the reaction can be troublesome. Acids often catalyze (increase the ...

This is traditionally removed in a ‘reduction clearing’ process with dithionite and alkali, with the same environmental question marks as for their use in the application of vat dyes. Dyes clearable on alkali treatment have been developed.74 In most polyester dyeing processes, a pH of 5–6 ...

A method is taught for increasing the yield of anhydrous sodium dithionite by adding an organic compound that is thiosulfate reactive to a batch reactor containing a puddle solution of methanol and fed with formic acid or an alkali formate as a first feed, an aqueous alkali compound as a ...
