General description

Titan(IV)isopropoxid ist eine Koordinationsverbindung auf Titan-Basis, die häufig in der asymmetrischen Sharpless-Epoxidierung von Allylalkoholen verwendet wird. Außerdem kommt sie in der Kulinkovich-Reaktion zur Herstellung von Cyclopropanol-Derivaten als Katalysator zum Einsatz.

Application

Bei der Zubereitung von Titandioxid (TiO2) häufig als Präkursor verwendet
In einem zweistufigen Sol-Gel-Verfahren wurden neuartige Metalloxid-/Phosphonat-Hybride aus Titan(IV)isopropoxid gebildet. Ausgangsmaterial für dünne Barium-Strontium-Titanat-Beschichtungen. Zur Herstellung poröser Titanosilikate; dabei handelt es sich um potenzielle Ionenaustausch-Materialien für die Beseitigung von radioaktiven Abfällen. Angewendet bei der Bildung eines Heterosupermoleküls, das aus einem TiO2 Nanokristallit-Viologen-Elektronenakzeptorkomplex besteht, dessen lichtinduzierter Elektronentransfer belegt ist.

Packaging

Die 25-ml-Sure/Seal™ Flasche wird für den Einmalgebrauch empfohlen. Wiederholte Einstiche führen höchstwahrscheinlich zu einer Leistungsminderung des Produkts.

Questions

1–9 of 9 Questions  
  1. 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/418/501/product-dating-information-06-25-mk.pdf

  2. 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

  3. Buongiorno, utilizziamo questo reagente per determinare la presenza di acqua nei solventi acquistati. Sapreste dirmi qual è la quantità minima di acqua che è possibile rilevare?

    1 answer
    1. While this material will react with water to form TiO2, the product is not specifically tested or used as a water scavenger. Unfortunately, there is no internal method or information available regarding this reaction. A brief search of the literature did not reveal any additional information.

  4. What is the equivalent weight of ttip

    1 answer
    1. The equivalent weight of this product can be calculated by dividing the molecular weight by the net positive valence. It has 284.22 grams of Titanium(IV) isopropoxide per mole of titanium, and 71.055 grams of Titanium(IV) isopropoxide per mole of isopropoxide. The equivalent weight would depend on the source. That is, if you are looking at the material as a source of Titanium(IV), you would use 284.22 grams. But if they are looking at it as a source of the strong base (isopropoxide ion), you would use 71.055 grams. When looking at the Titanium(IV) isopropoxide per mole of titanium, there are +4 positively charged valence electrons which resulted 71.055 for the equivalent weight.
