Calorimétrie
Peroxyde d'hydrogèneLe peroxyde d'hydrogène (H2O2), communément appelé eau oxygénée ou encore perhydrol (appellation industrielle), est un composé chimique liquide et visqueux, aux puissantes propriétés oxydantes (il est aussi réducteur). C'est donc un agent blanchissant efficace qui sert de désinfectant et (à haute concentration) d'oxydant ou monergol dans les fusées spatiales.

ZéolitesTags : Sodium percarbonate 15630-89-4 Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Heat flow calorimetry has been evaluated as an alternative technique to conventional stability testing of sodium percarbonate [15630-89-4] (SPC) based on analysis of the hydrogen peroxide content. Stability tests were performed with different SPC samples as well as under various experimental conditions. In general, stable samples exhibiting high concentration of hydrogen peroxide were accompanied by low heat flow values. It was found that the results obtained by heat flow calorimetry and conventional stability testing were in agreement. It was also demonstrated that the long-term stability could be predicted from heat flow data obtained during the initial stage of decomposition. Furthermore, different manufacturing and experimental conditions were manifested as a change of the heat flow curve. The results indicate that the rate of heat production is closely associated with the stability of sodium percarbonate, i.e. the rate of decomposition of sodium percarbonate. In presence of zeolite the stability of sodium percarbonate was reduced, particularly under humid conditions.

The interaction samples were characterized by XRD and TG. The experimental results showed that a-Na2Si2O5 and B-Na2Si2O5 sustained their phases after interacted with surfactants. The relative crystallinity of a-Na2Si2O5 had little change after interacting with surfactants exception of AOS because it had better adsorbable effect on the surface of a-Na2Si2O5 than LAS, K12 and AEO-9. At the same conditions, the amount of H2O and surfactants were both important factors on the relative crystallinity of béta-Na2Si2O5. It also was proved that the temperature had little influence on the relative crystallinity of both alpha-Na2Si2O5 and béta-Na2Si2O5. Compared with Al-d-Na2Si2O5, a-Na2Si2O5 and B-Na2Si2O5 were more stable than Al-d-Na2Si2O5 after interacted with surfactants.

The adsorbance could be calculated from the potential and concentration response characteristics of surfactant ion-selective electrode to get surfactant adsorption isotherm. Further experiment results show that the adsorbance was greatly influenced by pH of the solution. It is demonstrated that surfactant ion-selective electrode could be utilized to measure surfactant concentrations in solution after adsorption equilibrium without solid-liquid separation.

Li, Auteur Année de publication : 2010 Article en page(s) : p. 35-39 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Sodium salts fatty alcohol polyoxyethylene ether sulfonate isethionate Temperature tolerance Salt Interfacial tension Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Sodium salts of fatty alcohol polyoxyethylene ether sulfonates with different length of hydrophobic chain (CnE3SO3, n = 14, 16, 18) were synthesized from sodium isethionate, then the structure was verified by IR. The temperature resistance, calcium-tolerant stability and salt tolerance were evaluated by pyrogenetic decomposition, phase separation and middle phase emulsion respectively. In addition the mixture of CnE3SO3 and heavy alkylbenzene sulfonate (HABS) was studied. The results showed that : (1) CnE3SO3 was very stable at 150°C especially in neutral, weak acid and weak alkaline conditions ; (2) CnE3SO3 performed a good salt tolerance and have a rank of C18E3SO3 > C16 E3SO3 > C14E3SO3 ; (3) the calcium-tolerant stability of CnE3SO3 reached 8700 mg/L, 9500 mg/L and 10000 mg/L respectively ; (4) CnE3SO3 was very good for improving the salt tolerance of mixture of CnE3SO3 and HABS. C18E3SO3 was the best in mixtures of Daqing crude oil/water containing C18E3SO3 and HABS in a ratio of omega C18E3SO3):omega(HABS) = 3:7 and showed the strongest synergistic effect. The interfacial tension in the system Daqing crude oil/water reached a minimum in the order of 10–3 mN/m and was always below 10–2 mN/m for cNaCl from 0 to 15000 mg/L.

B-Na2Si2O5 changed to kanemite in distilled water. In water with Ca2+ or Mg2+, B-Na2Si2O5 transformed to a mixture of kanemite, Ca(OH)2 and amorphous silicate or a mixture of kanemite (NaHSi2O5 ·3H2O), Mg(OH)2 and amorphous silicate. a-Na2Si2O5 changed to an unknown phase in distilled water. In water with Ca2+ or Mg2+, a-Na2Si2O5 transformed to a mixture of unknown phase, Ca(OH)2 and amorphous silicate or a mixture of unknown phase, Mg(OH)2 and amorphous silicate. The experimental data showed that the divalent cation binding process of a, B-Na2Si2O5 belongs to a mixture process with divalent cations exchange with Na+ cation and precipitation in form of insoluble amorphous solid.
