Production of chlorine dioxide by chemical reduction of ammonium chlorate in aqueous acidic solution

Abstract: A novel method is described whereby chlorine dioxide is produced through the chemical reduction of ammonium chlorate in an aqueous acidic solution. The reduction reaction takes place at elevated temperatures with or without a catalyst. The reducing agent of this reaction is preferably hydrogen peroxide, glycerol, or sucrose. Chlorine dioxide may be produced in accordance with this invention at a substantially higher rate and in higher yield than with conventional methods using sodium chlorate. Further, the chlorine dioxide produced is substantially chloride-free. The ammonium sulfate by-product of this method has direct use as a fertilizer.

Pharmacokinetics of ruminally dosed sodium [36Cl]chlorate in beef cattle.

Abstract: The recently recognized potential of sodium chlorate as a possible preharvest food safety tool for pathogen reduction in meat animals has spurred interest in the pharmacokinetics of intraruminally dosed chlorate. Six Loala cattle were assigned (one heifer and one steer per treatment) to one of three intraruminal doses of radiolabeled sodium [36Cl]chlorate (21, 42, or 63 mg/kg body weight) administered in four equal aliquots over a 24-h period. Blood and serum were collected (29 samples in 48 h). Total radioactive residues were measured and the radioactive moieties were speciated. Chlorate appeared rapidly in blood and serum after dosing. For animals administered a dose of 42 or 63 mg/kg, the half-life of absorption was estimated at 0.6-0.9 h. Serum chlorate concentrations progressively increased with aliquot administration until peaking at 6-21 parts per million at 26 h. Between aliquot administrations, serum chlorate levels typically peaked in 3.5 h or less. The half-life of chlorate elimination ranged between 6.9 and 11 h, depending on the dose. Ultimately, absorption of chlorate removes it from its desired site of action, the lower gastrointestinal tract, thereby reducing its efficacy. Further research is needed to develop a chlorate formulation that will allow passage to the lower gastrointestinal tract.

Stable activation-state javelle water and preparation method thereof

Abstract: The invention relates to a javelle water and a preparation method thereof. The stable activation-state javelle water comprises the following components (wt percent): 4-7 sodium hypochlorite, 0.5-1sodium chlorate, 0.25-1.5 sodium chloride, 1-3 dodecyl dimethyl tertiary amine, 0.1-0.5 metal ion complexing agent, 0.1-0.5 organic phosphonic acid, 0.5-1.5 phosphonic acid, and water of rest percent. The preparation method comprises the following steps: according to the content and components, adding sodium chlorate and sodium chloride in the water and then stirring; adding the metal ion complexing agent and stirring the solution; adding the sodium chlorate and stirring the solution; adding the organic phosphonic acid and stirring solution; adding the dodecyl dimethyl tertiary amine and stirring solution; adding the phosphonic acid and stirring; and uniformly stirring the solution so as to obtain the javelle water. The javelle water provided by the invention has the advantages of stable quality, good sterilizing effect and convenience in use.

Enantiomorphism in sodium chlorate crystals

Abstract: Creation of enantiomorphous forms in sodium chlorate and enantiomorphous nature of surface micromorphology were studied by optical microscopy. It was shown that when the small number of crystals nucleates spontaneously in unstirred, unseeded solutions then exclusively left- (L) or right-handed (D) crystals can be formed. At the large number of nucleated crystals the probability of the creation of L and D form is nearly the same. L and D crystals can be distinguished by the shape of growth or dissolution centers.
