ECHA maintains the C&L Inventory, but does not review or verify the accuracy of the information. Substances indicated, in 2009, as being intended to be registered by at least one company in the EEA. English-Tamil dictionary. The ‘Substance identity’ section is calculated from substance identification information from all ECHA databases. Note that for readability purposes, only the pictograms, signal words and hazard statements referred in more than 5% of the notifications under CLP are displayed. The purpose of the information provided under this section is to highlight the substance hazardousness in a readable format. If no EU harmonised classification and labelling exists and the substance was not registered under REACH, information derived from classification and labelling (C&L) notifications to ECHA under CLP Regulation is displayed under this section. Metastannic acid is a hydrated tin oxide, which exhibits high specific surface area and nano-particulate primary particle size. This information is only displayed if the substance is well–defined, its identity is not claimed confidential and there is sufficient information available in ECHA’s databases for ECHA’s algorithms to generate a molecular structure. It is possible that a harmonisation is introduced through an amendment to the CLP Regulation. The quality and correctness of the information submitted to ECHA remains the responsibility of the data submitter. Molar Mass: 168.7241 Metastannic acid. This is unique source of information on the chemicals manufactured and imported in Europe. 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 catalytic activities were much higher than those of sulfated zirconias. [], and was also used for the initial development of high-accuracy ANLn composite electronic structure methods []. Metastannic acid precipitation? ECHA organises consultations to get feedback from all interested parties and to gather the widest possible range of scientific information for the regulatory processes. According to the reading, metastannic tin can be precipitated with the addition of sulfuric acid. disodium tetraborate EC no. The ‘Substance identity’ section is calculated from substance identification information from all ECHA databases. metastannic acid rus. However, substance notifications in the InfoCard are aggregated independently of the impurities and additives. Watch Queue Queue. InfoCards are generated automatically based on the data available at the time of generation. Metastannic Acid on heating gives. Some substance identifiers may have been claimed confidential, or may not have been provided, and therefore not be displayed. 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. Metastannic-acid sentence examples (I) Commercially pure tin is treated with nitric acid, which converts the tin proper into the insoluble metastannic acid, while the copper, iron, &c., become nitrates; the metastannic acid is washed first with dilute nitric acid, then with water, and is lastly dried and reduced by fusion with black flux or potassium cyanide. InfoCards are updated when new information is available. *Please select more than one item to compare The InfoCard summarises the non-confidential data of a substance held in the databases of the European Chemicals Agency (ECHA). metastannic acid rus. the electronic edition of the Official Journal of the European Union. BPR regulation aims to improve the functioning of the biocidal products market in the EU, while ensuring a high level of protection for humans and the environment.

Search. Acids differ in the number of protons they can donate. This information is only displayed if the substance is well-defined, its identity is not claimed confidential and there is sufficient information available in ECHA’s databases for ECHA’s algorithms to generate a molecular structure. This section is based on three sources for information (harmonised classification and labelling (CLH), REACH registrations and CLP notifications). 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. Sulfated and tungstated stannias were prepared from commercial Sn-gels of meta-stannic acids; the former showed catalytic activities higher than those of the materials obtained from conventional gels and of sulfated zirconias. More information about the EC Inventory can be found here. 5.The report estimates 2019-2024 market development trends of Metastannic Acid industry. метаоловянная кислота ryšiai: sinonimas – vandenilio trioksostanatas (2–)rūgštis statusas T sritis chemija formulė H₂SnO₃ atitikmenys: angl. Regulatory process names 3 IUPAC names 1 Other identifiers 1 . 215–540–4, is covered by three harmonisations: 005–011–00–4; 005–011–01–1 and 005–011–02–9), CLH information cannot be displayed in the InfoCard as the difference between the CLH classifications requires manual interpretation or verification.

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. Sodium acetate is usually produced as a salt when ethanoic acid reacts with sodium bicarbonate as shown in the reaction below: CH 3 COOH + NaHCO 3 CH 3 COONa + H 2 O + CO 2. Print infocard. It covers their hazardous properties, classification and labelling, and information on how to use them safely. A substance identified primarily by an EC or list number may be linked with more than one CAS number, or with CAS numbers that have been deleted. metastannic acid.
