- Aufreinigung
- Reinigung
Application
- Erschließung der Hochleistungs-HCl-Adsorption bei erhöhten Temperaturen: Diese Forschung demonstriert die Verwendung von Salzsäurelösung zur Synthese robuster Ca-Mg-Al-Mischoxide. Diese Materialien sind in Umweltanwendungen zur Adsorption saurer Gase von entscheidender Bedeutung, wobei die Arbeit die Rolle von Salzsäure bei der Entwicklung von Lösungen zur Bekämpfung der Luftverschmutzung veranschaulicht (Cao et al., 2024).
- Nachhaltige und umweltfreundliche Hemmung der Korrosion von Weichstahl: Hier wird Salzsäure verwendet, um neue, umweltfreundliche Korrosionsinhibitoren zu testen. Dies ist wichtig in Branchen, in denen die Aufrechterhaltung der Materialintegrität gegen chemische Angriffe von entscheidender Bedeutung ist, sodass die Arbeit die Rolle von Salzsäure in innovativen Materialwissenschaftsanwendungen unterstreicht (Rizi et al., 2023).
- Synthese von Zinkoxid-Nanostäben aus Zinkborat-Vorläufer: In dieser Studie wird Salzsäure bei der Synthese von Zinkoxid-Nanostäben verwendet, die für Superkondensatoranwendungen wichtig sind. Sie unterstreicht die entscheidende Rolle von Salzsäure in der Nanomaterialforschung und erweitert die Grenzen der Energiespeichertechnologie (Lefdhil et al., 2023).
- An improved digestion and analysis procedure for silicon in plant tissue: Salzsäure wird zum Aufschluss von Pflanzengewebe für die Analyse des Siliziumgehalts verwendet, was landwirtschaftliche und biologische Forschungsmethoden verbessert. die Bedeutung von Salzsäure in wissenschaftlichen Studien, die eine präzise chemische Verarbeitung erfordern, widerspiegelt (Langenfeld und Bugbee, 2023).
- N-N(+) Bond-Forming Intramolecular Cyclization of O-Tosyloxy β-Aminopropioamidoximes and Ion Exchange Reaction: In dieser Forschungsarbeit spielt Salzsäure eine wichtige Rolle bei der organischen Synthese, was ihre Vielseitigkeit bei der Entwicklung pharmazeutischer Verbindungen aufzeigt. Die Studie liefert Einblicke in die Synthese komplexer organischer Verbindungen, die in der medizinischen Chemie von entscheidender Bedeutung sind (Kayukova et al., 2023).
Packaging
Einzelne 2,5-l-Einheiten erfordern Dosenöffner für das Öffnen des Versandbehälters aus Metall.

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

How can the outer metal shipping container be safely removed to access the 2.5L container of Hydrochloric acid inside?
1 answer-
The packaging used for the Hydrochloric acid is described as an "8" CS OVERPACK CAN (802), SEAMED." There are two types of overpack cans: one resembling a paint can and the other resembling a large can of corn. For the paint can-style, a flat-bladed screwdriver can be used to pry off the lid, while the can of corn-style may require a can opener. Inside the can, there should be packaging material such as a side panel and absorbent sheet. The bottle itself is a PVC-coated glass bottle designed to prevent shattering if it is accidentally dropped.
