Introduction

Molecular Sieve 3A Zeolite Powder is a synthetic aluminosilicate material with a uniform pore size of about 3A(0.3 nm). It is made by replacing sodium ions in 4A zeolite with potassium ions.

FAQ

Q: What does 3A molecular sieve powder mainly adsorb?

A: It mainly adsorbs water molecules and small polar molecules smaller than 3Å, while excluding larger molecules.

Q: Can it be regenerated?

A: Yes, it can be regenerated by heating (typically 200–230°C) or by pressure swing processes.

Q: What is the difference between 3A and 4A molecular sieve?

A: 3A molecular sieve is produced by potassium ion exchange of 4A, resulting in a smaller pore size and higher selectivity for water.

Q: How should it be stored?

A: It should be stored in a sealed container in a dry and ventilated environment to prevent moisture absorption.

Q: Is it suitable for drying organic solvents?

A: Yes, it is especially effective for drying polar solvents such as ethanol and methanol.
