This article provides a comprehensive overview of Dabco® 33-LV, a versatile tertiary amine catalyst widely used in various industrial and laboratory settings. We will explore its specifications, applications, handling, safety precautions, and relevant regulatory information, addressing the user queries regarding "Dabco 33 Lv specs," "Dabco 33 Lv 280 57," and "Evonik Dabco 33 Lv."
1. Dabco® 33-LV Specs (Technical Data Sheet Information):
Dabco® 33-LV, also known as 1,4-Diazabicyclo[2.2.2]octane (DABCO) in a low viscosity form, is a colorless to slightly yellow liquid. Its low viscosity is a key differentiator from other DABCO formulations, making it easier to handle and dispense in various applications. While the exact specifications can vary slightly depending on the batch and supplier, typical properties include:
* Chemical Name: 1,4-Diazabicyclo[2.2.2]octane (DABCO)
* CAS Number: 280-57-9 (This addresses the query "Dabco 33 Lv 280 57")
* Molecular Formula: C₆H₁₂N₂
* Molecular Weight: 112.17 g/mol
* Appearance: Colorless to slightly yellow liquid
* Viscosity: Significantly lower than standard DABCO powder or high-viscosity solutions. The exact viscosity value will be specified on the individual product's TDS.
* Density: Typically around 0.95 - 1.0 g/cm³ (will vary depending on temperature). Consult the specific TDS for accurate values.
* Boiling Point: Typically above 240°C (specific value will be in the TDS).
* Melting Point: Typically around 156-160°C (specific value will be in the TDS).
* Solubility: Soluble in water, alcohols, and many organic solvents. Solubility data should be found on the specific TDS.
* Purity: Typically high purity, usually exceeding 98%, although this will be explicitly stated on the TDS.
2. Evonik Dabco® 33-LV:
Evonik Industries is a major manufacturer and supplier of DABCO catalysts. While Aldrich (Merck) distributes Dabco® 33-LV, the underlying technology and chemical composition are essentially the same as those produced by Evonik. The difference lies primarily in the distribution channels and potentially minor variations in packaging or specific product labeling. Both companies' products should adhere to the same high-quality standards and meet the same chemical specifications.
The information presented here is generally applicable to Dabco® 33-LV regardless of the specific supplier (Aldrich or Evonik). However, it's crucial to always consult the TDS from your specific supplier for the most accurate and up-to-date information on the exact specifications of the batch you are using.
