Regulatory process names 3 IUPAC names 1 Other identifiers 1 . https://doi.org/10.1016/j.apcata.2007.01.044. The latter led to the synthesis of a ceramics acid, calcined at >1000 °C, whose catalytic activity and acidity were intermediate between mordenite and silica–alumina. If a substance is classified under multiple CLH entries, a link to the C&L Inventory is provided to allow users to view CLH information associated with the substance and no text is automatically generated for the InfoCard. Substances listed in the EINECS, ELINCS, or NLP inventories. REACH registration dossiers have greater data requirements (such as supporting studies) than do notifications under CLP. This section is based on three sources for information (harmonised classification and labelling (CLH), REACH registrations and CLP notifications). However, substance notifications in the InfoCard are aggregated independently of the impurities and additives. Molar Mass: 168.7241 metastanato rūgštis statusas T sritis chemija formulė H₂SnO₃ atitikmenys: angl. Please upgrade your Internet Explorer to a newer version. If at least one company has indicated that the substance classification is affected by impurities or additives, this will be indicated by an informative sentence. For example, monoprotic acids (a compound that is capable of donating one proton per molecule) are compounds that are capable of donating a single proton per molecule. More information about the EC Inventory can be found here. Tungstated stannia (WO3/SnO2) was obtained by impregnating meta-stannic acid (Koujundo Kagaku Ltd.) with aqueous ammonium metatungstate (1–80 wt.% W) followed by calcining in air; the materials were examined in the dehydrations of methanol and ethanol and the isomerization of cycloheptane to methylcyclohexane. The Support section provides tools and practical guidance to companies which have responsibilities under the EU chemicals legislation. The type of uses and classifications may vary between different submissions to ECHA and for a full understanding it is recommended to consult the source data. The material finds application as a specialised grade for the production of ceramic pigments and for catalysis. Metastannic Acid H2SnO3 Molar Mass, Molecular Weight. We apologise for the inconvenience in the meantime. Lactic acid formation and removal rates increase as you run, bike or swim faster. The CLP Regulation ensures that the hazards presented by chemicals are clearly communicated to workers and consumers in the European Union through classification and labelling of chemicals. Harmonisation is based on the substance’s physical, toxicological and eco-toxicological hazard assessment. The substance identifiers displayed in the InfoCard are the best available substance name, EC number, CAS number and/or the molecular and structural formulas. Alfa Chemistry is the world's leading provider for special chemicals. The materials with small quantities of W gave their highest activities in the high temperature range of calcination, indicating the following tendency; the lower the quantity, the higher was the temperature showing the highest activity: 900, 1000, 1100, 1150, and 1250 °C for the materials with 20, 10, 5, 2, and 1 wt.% W, respectively. The CAS number is the substance numerical identifier assigned by the Chemical Abstracts Service, a division of the American Chemical Society, to substances registered in the CAS registry database. InfoCards are generated automatically based on the data available at the time of generation. метаоловянная кислота ryšiai: sinonimas – vandenilio trioksostanatas (2–) Skip navigation Sign in. Information on applicable regulatory frameworks is also automatically generated and may not be complete or up to date. This website uses cookies to ensure you get the best experience on our websites. The highest activity for the reactions of methanol and butane was brought out by the sulfation with 3–9 M H2SO4. Interpretation Translation metastannic acid rus. It covers their hazardous properties, classification and labelling, and information on how to use them safely. Those quantities of S were coincident with their catalytic activities for the reactions of methanol and butane. metastannic acid — metastanato rūgštis statusas T sritis chemija formulė H₂SnO₃ atitikmenys: angl. If the substance is covered by more than one CLH entry (e.g. Compare Products: Select up to 4 products. When you incinerate metastannic acid, SnO2 is produced. 6.Analysis of upstream raw materials, downstream demand, and current market dynamics is also carried out 7.The report makes some important proposals for a new project of Metastannic Acid … Registration, Evaluation, Authorisation and Restriction of Chemicals, Chemical Agents Directive and Carcinogens or Mutagens Directive, EC Inventory, Pre-Registration process, Other, Substances of very high concern identification, Recommendation for the Authorisation List, Getting started with EU chemicals legislation, Classification of substances and mixtures, Harmonised classification and labelling (CLH).
