Product Name – Titanium(IV) chloride, 1M solution in dichloromethane, AcroSeal® Quantity/Pack Size – 100ML, 800ML Form – Liquid solution Grade – AcroSeal® (high-purity, moisture-controlled) Application – Catalyst in organic synthesis, Lewis acid reactions, polymer production
Product Overview
This 1M Titanium(IV) chloride solution in dichloromethane (DCM) is a high-purity reagent designed for demanding laboratory applications where moisture sensitivity is a critical concern. The AcroSeal® packaging ensures an airtight seal, preventing degradation from atmospheric exposure and maintaining the reagent’s reactivity over extended storage periods. Titanium(IV) chloride, also known as titanium tetrachloride, serves as a potent Lewis acid and is widely utilized in organic synthesis for catalyzing Friedel-Crafts reactions, polymerizations, and other transformation processes requiring strong electrophilic activation. The dichloromethane solvent provides an inert, low-polarity environment, making this solution ideal for reactions where solvent compatibility is essential. The 1M concentration offers a balanced trade-off between reactivity and ease of handling, reducing the need for dilution while still allowing precise stoichiometric control. This product is particularly suited for applications where trace metal impurities or moisture contamination could compromise experimental outcomes, thanks to its rigorous purification and packaging standards.
FAQs
1. What precautions should be taken when handling this Titanium(IV) chloride solution?
This solution is highly moisture-sensitive and corrosive. Always handle it under an inert atmosphere, such as nitrogen or argon, using airtight syringes or cannula transfer techniques. Wear appropriate personal protective equipment, including gloves, goggles, and a lab coat, as it can cause severe skin and eye irritation. Avoid exposure to air or humidity, as it reacts violently with water to produce hydrogen chloride fumes.
2. Is this solution compatible with glassware, or should I use specific materials?
The solution can be stored and used in standard borosilicate glassware, but ensure the glass is thoroughly dried and free of moisture before use. For prolonged storage or highly sensitive applications, consider using PTFE-lined or polymer-coated containers to minimize potential reactions with residual moisture on glass surfaces. Avoid using plastic containers unless they are specifically rated for resistance to dichloromethane and titanium tetrachloride.
3. Can this solution be diluted further for lower concentration reactions?
Yes, the 1M solution can be diluted with anhydrous dichloromethane or other compatible solvents to achieve lower concentrations. However, ensure the solvent and dilution process are conducted under inert conditions to prevent hydrolysis. Use volumetric techniques with dry, calibrated glassware, and verify the final concentration via titration or other analytical methods if precision is critical.
4. How should this product be stored to maintain its stability?
Store the unopened AcroSeal® bottle in a cool, dry place, away from direct sunlight and heat sources. Once opened, reseal the container immediately after use and store it under an inert atmosphere, such as in a desiccator or glove box. Avoid storing near water, alcohols, or other protic solvents, as even trace vapors can initiate decomposition. For long-term storage, keep the temperature between 2°C and 8°C, but allow the solution to reach room temperature before opening to prevent condensation.
5. What are the signs that this solution has degraded or been contaminated?
Degradation or contamination is often indicated by a cloudy or particulate appearance in the solution, which suggests hydrolysis or precipitation. A yellowish or brownish discoloration may also occur if the solution has reacted with moisture or impurities. Additionally, the presence of hydrogen chloride fumes upon opening the container is a strong indicator of decomposition. If any of these signs are observed, the solution should not be used, as its reactivity and purity are likely compromised.
