  • A mild three-component reaction of aromatic aldehydes, alkyl bromides, and aqueous ammonia as the nitrogen source gives imines in very good yields. (organic-chemistry.org)
Titrant2
  • A redox titration is a titration in which the analyte and titrant react through an oxidation-reduction reaction. (khanacademy.org)
  • The best indicators need to have a potential oxidation value between the solution being titrated and the titrant. (publishthispost.com)
Potassium3
  • Drinking water also contains small amounts of manganese â ¦ Potassium react with water forming potassium hydroxide and releasing hydrogen. (ut.pr)
  • When potassium permanganate reacts with Sulphuric acid, potassium sulphate and two molecules of Manganese sulphate and three water molecules form. (publishthispost.com)
  • Hydrogen sulphide reacts with potassium permanganate and sulfuric acid lớn produce Sulfer, Manganese Sulfate, potassium sulfate as well as water. (org.vn)
Aqueous1
  • The reaction of aldehydes and aqueous ammonia with epoxides leads to imines bearing a vicinal hydroxyl group regioselectively. (organic-chemistry.org)
Sulfate reduction1
  • Under electron donor-limiting conditions, even a low concentration of sulfate (2 mM) resulted in a decreased PCB dechlorination rate by 88.7% in a co-culture comprising Dehalococcoides mccartyi CG1 and the sulfate-reducing bacterium Desulfovibrio desulfuricans F1, an inhibition which was attributed to the competition for electron donor between sulfate reduction and PCB dechlorination.

Radicals1
  • An efficient, metal and base-free, chemoselective reaction of boronic acids with cyanamidyl/arylcyanamidyl radicals provides primary aryl-, heteroaryl-, and alkyl amines at ambient temperature within 1 h. (organic-chemistry.org)
Crystal lattice1
  • Recently however, the idea emerged that reactions involving lattice oxygen (i.e., oxygen that's part of the crystal-lattice structure vs oxygen on the surface) could be useful for improving battery capacity. (lbl.gov)
Findings1
  • A manganese(ii) phthalocyanine under water-oxidation reaction: new findings. (ut.pr)
Process2
  • In the course of these interactions, energy can be transferred to and from the manganese ion by flipping its spin - a process commonly termed spin exchange. (lanl.gov)
  • as early as in the sintering process, so the CaO content in the primary slag of this kind of ore is higher The composition of slag also changes little in the process of slag reduction. (newdimensionsipm.com)

  • Removing Manganese from Water. (salesautopilot.com)
  • MANGANESE IN DRINKING-WATER 2 resulting in encrustation problems. (ut.pr)
  • Where any water has touched the tube green manganese VI will be formed instead. (ut.pr)
  • In deep water wells, manganese can be found in concentrations as high as 2 to 3 parts per million, although amounts are usually smaller. (ut.pr)
  • Manganese is a type of metal that is commonly found in the well water around the world. (ut.pr)
Acidic1
  • In this reaction, it acts as an acidic medium only. (org.vn)
Aerobic1
  • A modular aerobic oxidation of amines to imines has been achieved using an ortho -naphthoquinone ( o -NQ) catalyst. (organic-chemistry.org)
Concentrations1
  • The leaf nutrient concentrations defined as the critical value for each nutrient could result in a potential 5%-10% yield reduction from optimum. (ufl.edu)
Temperature1
  • [4] mixing, surface area, and temperature are important factors in reaction rate. (wikipedia.org)
