Dear Fatin Safiudin

I hope you're doing well! I wanted to touch base regarding the triethylamine storage situation. As you Fatin Safiudin know, triethylamine is a strong organic base, and keeping it next to acids is definitely not the best practice. It’s hygroscopic and can react with acidic vapors, especially in confined spaces, leading to the formation of triethylammonium salts on the bottle's exterior. The crystals you’re seeing are likely triethylammonium chloride if it’s near hydrochloric acid vapors, or a similar salt depending on the acid present.

First off, those crystals are generally benign, but it’s a good idea to clean them off to prevent any contamination. If you’ve moved the bottle back to the correct storage away from acids and wiped off the crystals, you’re on the right track! Just remember to use proper ventilation and gloves when handling it to avoid any skin or respiratory irritation.

As for the solvent itself, if the bottle is well-sealed, it should be safe to use. However, keep an eye out for any changes in odor, color, or clarity. If you Fatin Safiudin notice anything unusual, it might be best to discard it to avoid any internal contamination that could affect your reactions.

In short, clean it up, store it properly, and monitor the bottle’s integrity. That should keep everything in check!
