TL;DR: In this paper , a model was developed for predicting a locked signal under a series of refocusing pulses for Nuclear Quadrupole Resonance (NQR) of spin I=32 and tested with a powder of KClO3.
Abstract: A model was developed for predicting a locked signal under a series of refocusing pulses for Nuclear Quadrupole Resonance (NQR) of spin I=32 and tested with a powder of KClO3. This work represents the first direct NQR detection of the 39K line of potassium chlorate. The characteristic time constants, T1,T2e and T2∗, were measured to determine the detectability of potassium chlorate via 39K-NQR. The echo train T2e was found to be strongly dependent on the refocusing pulse-spacing and weakly dependent on the refocusing pulse strength. The optimal angles of the excitation and echo pulse for a pulse train were also determined, as well as, the resonance-frequency dependence on sample temperature.

TL;DR: In this paper, the basic experimental study of two kinds of sodium chlorate process technique proved that the SCLP technique shows outstanding superiority in conversion rate, purity of product etc.
Abstract: As a new type of disinfectant- Chlorine dioxide (ClO_2) has been generally accepted . And the sodium chlorate process due to its cost is much cheaper than that of sodium chlorite process is concerned with great interest. In this paper, the basic experimental study of two kinds of sodium chlorate process technique proved that the sodium chlorate, hydrogen peroxide, and sulfuric acid technique shows outstanding superiority in conversion rate, purity of product etc. It posesses good economic and social benlfit.

TL;DR: Sodium chlorate is prepared with increased Faraday yield using electrolysis in a tank equipped with metal electrodes coated with electrochemical activating agents, such as platinum-iridium or ruthenium oxide, in the presence of hydrochloric acid for pH control as mentioned in this paper.
Abstract: Sodium chlorate is prepared with increased Faraday yield using electrolysis in a tank equipped with metal electrodes coated with electrochemical activating agents, such as platinum-iridium or ruthenium oxide, in the presence of hydrochloric acid for pH control Phosphoric acid, in the required amount per 1 ton NaClO3 is 0.85-1.7 kg, is added into the electrolyte to increase the Faraday yield due to reduction of oxygen-gas generation.

TL;DR: In this paper, a comprehensive treatment method for 1, 4-diamino-2-anthraquinonesulfonic acid wastewater was proposed, which includes the steps of: adding industrial 1.4-Diamino, 2.5-anthrquinones sulfonic acid (A2A) wastewater into a container, calculating the content of sodium 3, 4dichlorobenzenesulfonate therein, according to a sodium 3.4:0.34-0.40, adding all the hydrochloric acid into the container, and
Abstract: The invention discloses a comprehensive treatment method for 1, 4-diamino-2-anthraquinonesulfonic acid wastewater. The method includes the steps of: adding industrial 1, 4-diamino-2-anthraquinonesulfonic acid wastewater into a container, calculating the content of sodium 3, 4-dichlorobenzenesulfonate therein, according to a sodium 3, 4-dichlorobenzenesulfonate, hydrochloric acid and sodium chlorate mole ratio of 1:0.34-0.4:0.34-0.40, adding all the hydrochloric acid into the container, and performing stirring till reflux; adding a sodium chlorate solution dropwise, maintaining a dripping speed of 20-30 drops per minute, at the same time maintaining a reflux oil separation state; at the end of dripping, maintaining the reflux oil separation state for 30-90min till no oil slick in condensate liquid, and separating trichlorobenzene. The method provided by the invention adopts chemical reaction, converts sodium 3, 4-dichlorobenzenesulfonate in wastewater into 1, 3, 4-trichlorobenzene, and separates 1, 3, 4-trichlorobenzene from wastewater by distillation, greatly reduces the COD of wastewater and reaches the emission standard. The small amount of recovered trichlorobenzene can be used or sold as a by-product, also the strong oxidizing properties of sodium chlorate can be utilized for complete oxidation decomposition of other unknown organic matters in wastewater, and the chroma of wastewater is reduced.

16 Apr 1998TL;DR: A method of purifying metal halides from organic and carbonaceous impurities involves heating a mixture of the solid halide with a solid additive which includes a halogen-oxygen bond and which dissociates at below the metal halide melting temperature.
Abstract: A method of purifying metal halides from organic and carbonaceous impurities involves heating a mixture of the solid halide with a solid additive which includes a halogen-oxygen bond and which dissociates at below the metal halide melting temperature. Preferably, the additive is a halogen-oxygen acid (or its alkali metal salt or anhydride) or a halogen oxide of the halide in the metal halide. Chlorides and bromides may also be purified using easily decomposable alkali salts of chlorine-oxygen acids and bromine-oxygen acids, e.g. caesium chloride may be purified using caesium perchlorate (CsClO4) at 250 deg C and sodium chloride may be purified using sodium chlorate (NaClO3) or sodium perchlorate (NaClO4) at 482 deg C. The amount of additive is unimportant. The purified metal halide may be transferred directly, without cooling, into a melting crucible for production of large crystals by the Bridgeman-Stockbarger or Czochralski process.
