Seeking advice on the issue of neutral materials becoming acidic after water removal using molecular sieves
Thread Content
The company has a setup that produces a finished product with an acidic pH of 1. After alkaline washing, this product becomes neutral, but once water is removed using molecular sieves, its pH returns to 1 again. What is the reason for this?
It may be useful to consider the characteristic factors of molecular sieves for reference.
What kind of material is this? Is it a single substance or a mixture, a gas or a liquid? This way, it’s impossible to discuss
Single material: hexamethyldisiloxane, the hydrolysis product of trimethylchlorosilane
It’s possible that the alkali wash wasn’t carried out until neutrality was achieved before the material was fed into the molecular sieve; check the process execution
