Allgemeine Beschreibung

Wir verpflichten uns, Ihnen umweltfreundlichere Alternativprodukte anzubieten, die mit einem oder mehreren der „12 Prinzipien der Grünen Chemie“ im Einklang stehen. Dieses Produkt ist bioerneuerbar und steht im Einklang mit den Prinzipien ″Sicherere Lösungsmittel und Hilfsmittel″ sowie ″Nutzung nachwachsender Rohstoffe″. Weitere Informationen finden Sie hier.

Cyren ist ein dipolares, für die End-of-Life-Entsorgung sicheres Lösungsmittel auf biologischer Basis, das zu CO2 und H2O zerfällt. Es ist eine aprotische Alternative zu gängigen Lösungsmitteln, die bedenklich in Hinblick auf den Umweltschutz sind. Cyren™ ist eine Alternative für viele Lösungsmittel, die von REACH als besonders besorgniserregender Stoff (SVHC) eingestuft wurden, z. B. N-Methylpyrrolidon (NMP) und N,N-Dimethylformamid (DMF).

Anwendung

Cyren wird in einigen Anwendung als Ersatz für NMP und/oder DMS eingesetzt. Zum Beispiel hat sich gezeigt, dass es die Dispergierfähigkeit von NMP für Graphenlösungen aufgrund seiner optimalen Polarität und hohen Viskosität übertrifft und größere und weniger fehlerhafte Graphenflocken bildet. Nachstehend finden Sie weitere Verwendungszwecke für Cyren™.

1. Dispergierfähigkeit für Graphenlösungen.[1]
2. Alternative zu DMF bei der Synthese von metallorganischen Gerüsten.[2]
3. Organische Synthese:

Leistungsmerkmale und Vorteile

Greener Alternatives Evaluation Matrix

Green chemicals evaluation aligns with the 12 Principles of Green Chemistry, emphasizing resource efficiency and hazard reduction.

Biorenewable Solvents

Why should you have to choose between solvents that are ecological and those that are reliable? Enjoy both at once with our biorenewable and greener solutions. Cyrene™ solvent is a new dipolar aprotic alternative to common REACH restricted solvents, such as N methyl-2-pyrrolidone (NMP) and Dimethylformamide (DMF).

Biobasierte Lösungsmittel

Warum sollten Sie sich zwischen ökologischen und zuverlässigen Lösungsmitteln entscheiden müssen? Entscheiden Sie sich für beides – mit unseren biobasierten und umweltverträglicheren Lösungen. Lösungsmittel der Marke Cyrene™ sind eine neue dipolare, aprotische Alternative zu gängigen Lösungsmitteln, die unter die REACH-Verordnung fallen, wie N-Methyl-2-Pyrrolidon (NMP) und Dimethylformamid (DMF).

Questions

1–7 of 7 Questions  

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. 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

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  4. What is the recommended operating temperature for stripping photoresist on Silicon or GaAs semiconductor wafers when using Cyrene?

    1 answer

    1. It is known that research is currently underway in this area and Cyrene™ has shown promise. However, due to the confidential nature of these processes, a specific recommended operating temperature cannot be provided. Nevertheless, it's worth noting that the safe operating temperature of neat Cyrene™ is below 140 °C. It is advisable for the user to conduct additional safety checks and tests for their specific application.

  6. Why should you use BioRenewable solvents?

    1 answer

    1. You will contribute to create a sustainable world, significantly lowering environmental impact. Biorenewable solvents also decrease petroleum sources dependency, have higher recovery rates, and/or are safer for handling and disposal.

      Helpful?

  7. Do BioRenewable solvents have a similar quality to petroleum-based solvents?

    1 answer

    1. BioRenewable solvents can have the same or higher purity level compared to traditional solvents. These solvents are free of the many byproducts of petroleum manufacturing, such as benzene, aldehydes, and ethers.

    Cyrene as a polar solvent

    We have used Cyrene as a replacement solvent to DMSO and it has worked very good. It dissolves all of the reagents very well, and the resulting product is very similar. There is some odor to it, but as long as you work in a fume hood it is not a problem.
